HiZ and LoZ: When To Use HiZ-70V, HiZ-100V, and LoZ

HiZ and LoZ: When To Use HiZ-70V, HiZ-100V, and LoZ

Our smart amplifiers give users the ability to customize their HiZ/LoZ settings for each individual amplifier channel.

By visiting the settings page of our UI (gear icon), you can select HiZ-70V, HiZ-100V, or LoZ for each channel.

So, for instance, channel 1 can be set to LoZ, while channel 2 can be set to HiZ-100V.

This gives integrators the flexibility to power a variety of different types of speakers on a single amplifier, instead of having to buy one amplifier for the 70V or 100V zones and another amplifier for the low impedance zones.

But for those who may be new to configuring professional audio systems, these terms might cause some confusion.

Let’s dive into what each setting actually means and when to use them.

THE DIFFERENCES BETWEEN HIZ-70V, HIZ-100V, AND LOZ

HIZ AND LOZ: WHEN TO USE HIZ-70V, HIZ-100V, AND LOZ

Before we get into the specific differences, it’s good to talk about impedance.

Impedance is the resistance to an alternating current in a circuit. You can measure impedance in units called ohms. You’ll definitely see this show up on spec sheets and manuals whenever you’re working with audio products. Ohms are represented by the ohm symbol which looks like this – Ω.

When we’re talking about things like HiZ and LoZ, we’re referring to a specific impedance range.

HiZ is a higher impedance range. LoZ is a lower impedance range.

So, the “Z” in these terms actually represents the word impedance. 

90 + 90 + 90 + 90 + 90 + 90 = 540 Watts

In HiZ applications, you won’t have to calculate the actual impedance.  You simply add up the wattage of all the speakers tapped on each 70V or 100V Zone.  A good rule of thumb to follow is to have 20% of power above the calculated total wattage needed, this will ensure that you have sufficient headroom to achieve high-quality audio, even during high transients in the source material.

For example, if you have a 700-Watt amplifier channel at 70V or 100V, you’ll want to take 700 x 0.8 which equals 560 Watts.  If you want to follow the 20% headroom rule, you will only want to tap 560 watts worth of speakers.

In LoZ applications, if you are connecting more than one speaker you will have to do an impedance calculation using ohms law and then also add up the wattage of the speakers.  If the impedance isn’t too low and the total wattage of the multiple speakers is below the amplifier’s power rating, then the system should operate properly and safely.

Let’s look at each individually.

Total Impedance = R1 x R2 / (R1 + R2) | 4Ω = 8 x 8/(8+8)

HIZ-70V

HIZ AND LOZ: WHEN TO USE HIZ-70V, HIZ-100V, AND LOZ

70V systems are known as constant voltage systems and are most commonly used in commercial audio systems in the United States depending on local regulations and system requirements.

These systems allow for longer cable runs and more speakers per amplifier, and in many instances, smaller gauge cable can be used to save money.

This setting is ideal for commercial buildings, corporate applications, retail, educational, government, and public address systems.

HIZ-100V

HIZ AND LOZ: WHEN TO USE HIZ-70V, HIZ-100V, AND LOZ

100V systems are also constant voltage systems. However, this setting is most commonly used in European countries and other regions outside of the United States. Some systems with this setting may require cables to be run through conduits.

100V systems have the same benefits as a 70V system with a couple of advantages, because of the higher operating voltage the impedance stays high, resulting in lower current, allowing for smaller gauge wire across even longer distances and in some instances the ability to power more speakers.

This setting is ideal for commercial buildings, corporate applications, retail, educational, government, and public address systems.

LOZ

HIZ AND LOZ: WHEN TO USE HIZ-70V, HIZ-100V, AND LOZ

Low Impedance systems, also known as 8Ω systems, are ideal for high-performance applications requiring higher fidelity. These systems are commonly comprised of speaker components that require more power.

LoZ systems require shorter cable runs for optimal performance.  In some instances, depending on the power of the speaker and the length of the cable run, a higher gauge cable may be required to account for line loss over the length of the cable run. 

This setting is most commonly found in applications such as nightclubs, live performance systems, churches, and restaurants.

THE BROADBERRY UPGRADES WITH MARTIN AUDIO TORUS

Popular Richmond, VA live music venue, The Broadberry, has taken delivery of a new Martin Audio TORUS constant curvature array, supplied by locally based rental partner, Soundworks of Virginia.

Soundworks has been working with the 550-capacity venue, owned by Lucas Fritz and Matt McDonald, providing sound for their outdoor concerts since the Spring of 2021.

Explaining the rationale behind the venue upgrade, Fritz says they had been making do with the old system that was in the venue when they took over in 2014. “We were well overdue for a PA overhaul, especially given the calibre of artists we were continuously bringing to the market. We had been working with Soundworks and knew they wouldn’t lead us astray.”

The venue’s production manager Justin Lewis confirms that the previous system had been poorly deployed—and he had a firm idea in mind for its replacement.

WE ARE EXTREMELY EXCITED ABOUT OUR NEW TORUS RIG.

Lucas Fritz/The Broadberry

“Due to the shape of our room I wanted a box with a relatively narrow horizontal pattern. All the line arrays I looked at were too wide and point source didn’t provide the flexibility we wanted in vertical coverage.”

He looked at a number of systems and consulted his crew, ultimately deciding constant curvature would probably be the best for our room. “We chose TORUS mainly due to Soundworks’ existing relationship with Martin Audio, and the cardioid feature of the SXC118 was also a positive influence on our decision.”

Taking up the story, Soundworks’ CEO, Steve Payne, adds, “Their trust in the Martin Audio name, and belief that anything with that badge on it would be a quality solution, was reinforced by the [Wavefront Precision] WPL and WPC systems Soundworks had been routinely providing for their outdoor concerts.”

And while he admits the Wavefront Precision series remains his “hands down favourite,” for an installation situation he needed to look no further than TORUS. “I think this system, with its variable horizontal coverage and choice between 30° and 15° vertical angle is a better solution than a short hang of WPS,” he says, concurring with Justin Lewis.

The pair of three-box hangs comprise two T1215 and a single T1230 at the base, to eliminate the desire for front fills. The arrays are supported by TORUS fly bars hung from Unitruss, which spans the structural roof girders. Four SXC118, ground stacked in a central cluster under the stage, provide the low end, and all processing is via the onboard DSP in the Martin Audio iKon multi-channel amplifiers.

Soundworks’ project manager Bryan Hargrave masterminded the installation, in conjunction with Martin Audio US Technical Support Engineer, Joe Lima.

Summing up, Justin Lewis says, “The coverage and sound quality are just about perfect now, and the rig is a vast improvement over our old one. Our crew is pleased, and we’ve had generally good responses from guest engineers.

And Lucas Fritz is equally effusive. “We are extremely excited about our new TORUS rig. The room sounds better than it ever has,” he exclaims.

BBC RADIO 1’S BIG WEEKEND RETURNS … WITH RG JONES AND MLA

Martin Audio’s MLA system for the first time on the main stage of Radio 1’s Big Weekend that took place at Memorial Park, Coventry, with the popular music festival finally returning after the hiatus caused by Covid-19.

An audience of 40,000, and an array of premiere acts that included Harry Styles, George Ezra, Ed Sheeran and Calvin Harris, played across two nights in the city of Coventry’s beautiful, historic park. The show was new to RG Jones, who tendered successfully for the event. The production company were delighted to get the chance to flex their sonic muscles on such a high-profile project while re-connecting with long-standing clients Dick and Frankie Tee from EnTEEtainment, and reminding Festival Republic, who managed the event, what the company can do.

Being an urban site, noise management was of the highest priority, but Coventry’s status as 2022 City of Culture has also meant that throughout the year events of all shapes and sizes are taking place and the city council are keen to make the most of the opportunities that City of Culture affords. A generous offsite limit of 75dBA Leq15was relatively straightforward to achieve for MLA and its ability to control offsite noise, despite some strange acoustics surrounding the nearest houses.

Main PA hangs of 14 MLA elements were boosted by a central cardioid sub array of 22 MLX, asymmetrically steered to help with offsite C-weighted levels. In addition, MLA Mini and DD12 provided frontfills, MLA Mini and MLA Compact outfills, and there were two delay positions of 12 MLA Compact, and a single central position of eight MLA. Most impressive was the MLA Mini outfill—with a hang of 12 enclosures covering about 75m and easily keeping up with the stage right MLA.

The RG Jones crew featured a blend of seasoned A-team regulars and some newbies. “It’s so crucial to have the right team on these shows and bringing some new faces into the circle of trust is both exciting and invaluable,” believes Simon Honywill. At FOH were RG’s regular Damion Dyer, and the experienced Chris Pyne, running the twin DiGiCo SD12 A/B desk system.System tech was Matt Besford-Foster, who was fresh off MLA training and getting amongst his first MLA system, having spent many years travelling the world with Muse and Elbow.

His verdict on MLA could scarcely have been more positive. “I was very impressed with the tonal signature across the MLA range,” he said. “MLA Mini seemed to defy physics with their ability to sit alongside MLA as a side hang and hold their own.”

On stage were Mark Isbister, in his regular role as patch master and interface with the BBC, assisted by Chris Lambert and RG’s own Rosie Tarrant.Looking after monitors were Martin Dineley and Sam Manigley.

Simon Honywill was responsible for system design and used Martin Audio’s new 3D prediction software – DISPLAY 3 — to generate a series of plots for environmental sound consultants, Vanguardia. “For me it was interesting to actually deploy a system that was mapped in DISPLAY 3 for the first time. I worked hard to design a system that would deliver the best possible experience for the audience of course, but also looked into restricting coverage on the house right side of the arena, where there was a large bar and toilets, and beyond the perimeter fence was the closest noise monitoring point.

“I had some reservations about using 12 MLA Compact on the outfill that covered that area, but in fact it was the right choice as the crowds thinned out significantly there and we were able to control coverage very effectively and run the headliners at a comfortable 98dBA.”

Frankie Tee was also fulsome in her praise for the sound coverage. “It was a real pleasure to be back working with RG Jones again after so many years. We knew they would deliver a great service to the Radio 1 event, and we only had positive feedback from the clients, broadcast and artists, proving we were in safe hands.

“The site faced some challenges with nearby properties, but Simon and the team were able to very accurately not only predict offsite noise levels, but stick to them too. I very much look forward to hopefully many more events together!”

CAPITAL SOUND EXTENDS AND ENHANCES MARTIN AUDIO’S PA TO FIT BST’S ENLARGED STAGE

With artistes ranging from the Rolling Stones to Elton John and the Eagles gracing the new supercharged stage and fascia at this year’s American Express presents BST Hyde Park the quality of sound literally needed to raise the bar at AEG Live’s flagship event.

Martin Audio rental partners Capital Sound (part of the Solotech UK group) have been the exclusive suppliers of the manufacturer’s ground-breaking MLA since the event’s inception in 2013, and were able to respond by providing enhanced site coverage. This year, with its expansion across three weekends, the event broke all records, selling 530,000 tickets across the nine shows.

Taking note of the additional 5-metre height gain of Star Group’s new Titan stage (which now reaches 19 metres off the ground), Solotech extended the two main PA and sidefill hangs and streamlined the 11 delay towers, introducing their recently acquired WPL scalable line array—the largest in the Wavefront Precision family.

This resulted in no fewer than 182 Martin Audio line array elements being deployed at the event as well as 44 subwoofers.

Stated Solotech Senior Technical Advisor, Robin Conway, “Had we used the original plot, the hangs would have been out of proportion. So I looked at issues such as trim height, and both visually and performance wise, by increasing the box count we managed to achieve better results, with more energy at the front.“On top of that, we also managed to achieve the trim height we wanted, with the main hangstrimmed this year at 16.2m from the ground (as opposed to 12.5 previously, and the sides at 17.5m, compared to 14.5m.”

Aesthetically the stage design also had to work around a newly-created tree, the central focal point of the stage, while mechanically a wrap-around video screen was introduced for the first time—also masterminded by Solotech.

The main PA this year was increased by four elements, and comprised 19 MLA and a single MLD Downfill each side, with 15 MLA and an MLD Downfill as side hangs (two each side larger than previously). Arranged in a broadside cardioid array were 32 MLX subwoofers while six pairs of MLA Compact provided front fills.

The delay positions had also been extended, with longer hangs. Of the 11 masts, positions 1-5 were identically configured with seven MLA and an MLD Downfill; the Delay masts 6-9 behind the FOH mix tower comprised an extended 10 WPL and three SXH218 in a cardioid stack, while Delay points 10 and 11 were each populated with eight WPC elements.

All Wavefront Precision enclosures were driven by Martin Audio iKON multi-channel amplifiers in the optimum 1-box resolution, and the sound was again carried site wide on an Optocore fibre ring, which offered full redundancy.

The quality of the PA this year was once again exemplary, no better so than for Adele … a fact to which the many social posts attested.

Once again Solotech fielded a highly accomplished technical team, working through the event’s long-term production manager, Proper Productions’ Mark Ward, with Tim Patterson as crew chief, Johnny Buck (monitor engineer), Mike Warren (FOH engineer) and Joseph Pierce system tech. Martin Audio’s former technical director, Jason Baird, was brought in as consultant for the set-up.

Solotech senior project manager Martin Connolly, was delighted with both the onsite and offsite sound thresholds, which met the approval of acousticians / noise control consultants, Vanguardia. “Following propagation tests, we managed to achieve great level—an increase on what we have had in the past and with a bit more control,” he said.

This was particularly evident in performances by Elton John and Adele, as Connolly explained. “Elton John was 100-101dB(A) and Adele was 102dB(A) LEq (1 min) and 101dB(A) LEq 5 mins, with 75dB(A) offsite.”

He said the event had fully justified their decision back in Spring this year to invest further into Wavefront Precision—with an acquisition countenanced by Solotech. As a result, WPL and WPC now complement the WPS system they had earlier bought for the Tim Minchin tour.

Along with the two new WPs Solotech also purchased TORUS for their hire inventory—part of an order amounting to well over 100 enclosures. “Had we not done so, looking at our order book for the summer we would simply have had to sub-hire in,” stated Connolly.

As for the video displays, Solotech provided a near 1500sq.m screen measuring over 16m high for main stage including 4500 Saco tiles and 540 Roe CB5 LED panels on main stage screen. A further 300 Roe CB5 were deployed for delays, relays and for Stage 2.

Summing up the event, and the technical excellence of the sound reinforcement, production director Mark Ward said, “There were a lot of conversations about how to make the PA sound great and feel in proportion on Star’s vast new Titan stage. Solotech and Martin Audio got fully engaged in figuring out solutions and we more than achieved the result we were after—both sonically and aesthetically. It looked ‘right’ and sounded brilliant.”

SOLOTECH FIELDS MASSIVE 23 HANGS OF MLA/WAVEFRONT PRECISION FOR STEREOPHONICS

When Capital Sound, part of the Solotech UK Group, conceived the original design for Stereophonics’ homecoming concert at the Principality Stadium, for what would have been their ‘We’ll Keep A Welcome’ Christmas show, the idea of 23 Martin Audio PA hangs (covering both an A stage and 40-metre thrust to a B stage) was entirely achievable.

“The kit was already prepped and ready to go out, when the show was suddenly cancelled,” states Solotech Senior Technical Advisor, Robin Conway.

But when the gig was rescheduled for June, there was none of the luxury of pre-production time that had accompanied the original show. Not only did the B stage now need to function as a totally independent stage, with its own PA, (rather than simply as a delay stage), but Friday’s planned production/build-up day suddenly disappeared when the following night’s concert—which also featured Tom Jones—sold out; this resulted in a second date being added … on the Friday!

The support line-up also changed at the last minute (with Newport-based Feeder coming in), while back at London HQ the crew worked around the clock to deprep inventory returning to base from other festivals (in what has become a frantic summer season for all PA companies as the event industry strives to recover), before reprepping and trucking it down to Wales.

Of course, the crowd of 74,000-plus who filled the stadium under its closed roof were oblivious to this, and reveled in the kind of first-class, evenly balanced coverage for which Solotech and Martin Audio are renowned. There was no compromise to the sound despite the production company needing to make a late provision for the incoming film crew, necessitating them to provide a separate broadcast feed in addition to the sound in the bowl.

Thus there was plenty to occupy the minds of the band’s long-serving sound engineer Dave Roden, Crew Chief, Tim Patterson, and system tech Mark Cleator, working alongside production manager Dave Nelson. Not least of these was how to create 360° of coverage via the B stage system, with two hangs facing back towards the main stage, which obviously meant the audience had to turn around to see when the band performed there.

The main PA hangs from A stage comprised 18 MLA and one MLD (Downfill) enclosure per side. Behind them were two hangs of seven MLX subs in end-fire configuration, with side hangs consisting of 16 MLA per side. Front fills comprised eight XD12 and 16 WPS (set in pairs on a shelf across the front of the stage).

For the B stage Cap turned to their new Wavefront Precision (WPL). These hangs comprised 12 x SXHF218 in a single column, with 36 flown WPL—18 on either side of the subs—while outflanking these were two further hangs of 14 WPL and two hangs of WPC facing the main stage to complete the 360° coverage. The Wavefront Precisions were driven in 2-box resolution from 24 iKON iK42 multi-channel amplifiers in a flown amplifier cart directly over the B-Stage.

The ring delay system, meanwhile, comprised eight hangs of eight MLA Compact.

Robin Conway explained the processing rationale. “Without the luxury of time we used a Dante-enabled Soundweb BLU-806 to create a custom-delayed matrix. Any part of the PA system applicable to A or B stages had different delay taps (for instance the ring system had two different times programmed as the action shifted from A to B stages).” These delay taps allowed the FOH team to choose the entire system focus dependent on which, or how many, band members were performing on which stage at any given time.

“Overall, we got the result we wanted in the face of enormous challenges, and in fact this probably broke some kind of internal record. I doubt, in our history, we’ve fielded 23 separate hangs of PA for a one-off gig before.”

LEA Amps Power High School Performing Arts Center: Tumwater High School

Tumwater High School in Tumwater, Washington, has an ambitious and growing Performing Arts Center that needed a powerful and dynamic audio system to match. For that reason, when the school sought to upgrade the audio amplification system for their main theater and other support spaces, they chose LEA Professional.

Let’s dive in!

THE SPEC

THE VENUE

LEA AMPS POWER HIGH SCHOOL PERFORMING ARTS CENTER: TUMWATER HIGH SCHOOL

The school’s Performing Arts department hosts everything from plays and musicals to ensemble performances, solo instrument recitals, and vocal/choir and spoken word performances. The main theater has seating for about 200. There are also large classrooms on each side of the theater that can hold an additional 100 each. When needed, the airwalls between the theater and the classrooms can be opened up to accommodate an audience of about 400, making the Tumwater High School the largest venue in the school district.

THE INTEGRATOR

LEA AMPS POWER HIGH SCHOOL PERFORMING ARTS CENTER: TUMWATER HIGH SCHOOL

Tumwater-based CCI Solutions are experts in sound and visual technology. The company has 40 years of experience helping people be seen and be heard throughout the US. CCI Solutions has designed and implemented over 1000 projects in church, corporate, government, and public facilities.

THE INSTALL

LEA AMPS POWER HIGH SCHOOL PERFORMING ARTS CENTER: TUMWATER HIGH SCHOOL

Mark Pearson, from national AVL systems integration company, CCI Solutions, served as the Project Lead for the Tumwater installation. Pearson explained that the main space and each side classroom space has its own sound system, but they also needed to work together for larger performances. The main space also required an update of its stage monitor amplification. The high school predominantly uses passive line array elements and monitor enclosures from Martin Audio.

“Months ago, we had specified amps from a different manufacturer for this project, but they weren’t able to deliver, so our rep firm recommended LEA amps, and it has turned out to be a great experience,” said Pearson. “Van Browne from Brownestone sent us some sample LEA amps to play with, our whole team just kind of fell in love with them. It’s always great to discover a high-quality, new product line that fits well into your offerings.”

To cover the spaces adequately, Pearson and the CCI team used a mix of four different Network Connect Series amplifiers from LEA Professional. The system solution included ten individual channels of monitoring ability (a single Connect 352 and two Connect 354 amps), allowing the high school to cover the stage monitoring, but also room to place speakers off stage to support special effects or to power additional floor monitors for larger groups. They also now have a four-channel 2 unit (four zones of 70 Volt with a Connect 84 amp) handling the back of house paging and stage manager announcements. And each side classroom has its own Connect 702 amplifier.

“These amps have an impressive list of features we really like,” added Pearson. “They’re networkable and controlled via IP addresses so we can easily access them with an app, and then the ability to have internal DSP in the amp for detailed speaker tunings; and then I also like that they’re GPI controllable and the side rooms can be turned on or off depending on the users need.”

To simplify the use process, Pearson set up the amps with a series of relays. If one relay is opened up, then the GPI triggers and powers up the amps. They have four relays in use — two for each amplifier. One relay is controlled off the DSP for the main house, and then another relay is controlled from a touch panel in each classroom. If students need to turn on the system for a classroom, they can now power on the system with a single touch, which opens a relay. With a single touch, the amplifiers power-up, a projection screen is lowered, and a protector is turned on — everything is ready to go.

“Because of delivery issues, this was a spec swap, but the high school ended up with a much better amplifier and a more robust system,” added Pearson. “Which is why we as a company are basically moving away from the other company to all LEA Amp solutions for this type of application and many more.”

Potvin did need to fix one issue in the hotel after the installation but was able to use the LEA Professional Web UI so he never had to step foot in the AV room. The Web App UI is LEA Professional’s browser-based interface which allows local monitoring of every amplifier connected to the network from any phone, tablet, or PC. In addition, it will enable users to view the status of every channel on any given amp. This alongside the remote control LEA Cloud platform, ensures the integrator, in this case, Potvin is in complete control of the system at all times.

THE CONCLUSION

LEA AMPS POWER HIGH SCHOOL PERFORMING ARTS CENTER: TUMWATER HIGH SCHOOL

Because of the pandemic and the summer break, the system has not yet been used for a full performance, but the high school is very anxious to get the system in use soon. The team ran several sound tests with various configurations, and everyone is very happy with the quality and headroom of the amplifiers.

“The installation was really smooth; we didn’t have any hurdles. That’s another plus for LEA, everything is very self-explanatory, and you don’t have to be an engineer to walk through the process to program things and get things up and running; it’s all very straightforward and logical,” said Pearson. “The amps themselves have a good user interface, and the app is beneficial. We had one question about the relays and the GPI interface we weren’t sure about, so we called LEA, and we had
our answer instantly. They were great to work with. I look forward to many more installations with LEA.”

We’d like to thank Mark Pearson and his team at CCI Solutions for choosing our amps for this killer installation and we hope that the audio systems will continue to deliver reliable audio for students at Tumwater High School for years to come.
