HIGH-QUALITY COMMERCIAL AUDIO SYSTEMS MAKE GOOD BUSINESS SENSE

Background music systems have been shown to have a huge influence on people in just about every situation. However, an area that has been overlooked is the effect that the quality of the music has on human behaviour.

Research has highlighted the way that music can affect consumer habits in a retail environment, employee focus in a workplace and relaxation in a hospitality setting. The first studies into the effects of music on shoppers were published more than 30 years ago and these results have been confirmed and refined time and again since then. Findings by PPS PRL[1] showed that two-thirds of UK adults say that the type of music a shop or business plays influences what they buy. The same survey also found that classical music encourages restaurant diners to order expensive items on the menu and that more than two-thirds admit to leaving a venue after realising that no songs were playing.

Further research, published by JAMA Network [2], notes the implications that music can have in other hospitality settings, such as hotels and spas. This research shows that music can make a positive change in health-related quality of life, which highlights the important role that a commercial audio system plays in therapeutic settings such as spas.

A slightly more contested area is the use of audio in the workplace. This is a subject that has seen a large amount of research, with results that have often been contradictory. Some papers have found that listening to music with lyrics while reading or working can decrease concentration or cognitive performance (Shih et al., 2012 [3];Liu et al., 2021 [4]). On the other hand, a number of studies have shown oppositely that natural-occurring sounds such as white noise, or highly composed sound such as classical music, can be beneficial for increasing focus and can even improve learning outcomes (Davies, 2000 [5];Chou, 2010 [6];Angwin et al., 2017 [7];Gao et al., 2020 [8]).

Recently published research [9] seems to back both of these findings. Amongst its conclusions, the study states: “We found that while performing a self-paced task for a long period of time (such as working), personalised soundscapes increased focus the most relative to silence. Curated playlists of pre-recorded songs by Apple and Spotify also increased focus during specific time intervals, especially for the youngest audience demographic.” Looking more specifically at the effects of different types of audio, the study concluded: “We found that based on our model, engineered soundscapes and classical music are the best for increasing focus, while pop and hip-hop music are the worst.”

It’s clear then that the type of music you play over a commercial audio system will influence your audience, and that crafting the right playlist can have positive results for your business. However, there is one element that none of these studies consider, the quality of the audio your audience hears over the background music system.

There has been less research in this area, and the majority is focused on the quality of audio over consumer equipment. However, there are some useful parallels that we can take from this research and apply it to people listening to background music in over commercial audio systems.

One of the issues with studying this area is that music is very subjective, and different people can have vastly different opinions on the same piece. To overcome subjective issues such as this, researchers use Quality of Experience (QoE) as a way that allows participants to report and rate experiences in a way that can be quantitatively analysed.

The QoE methodology has been further refined with a standard measure just for audio – Overall Listening Experience (OLE). First defined in 2013 [10], the term is used to describe the degree of enjoyment whilst listening to audio. OLE and QoE are comparable in the sense that they both try to take into account all possible factors that may influence enjoyment. These elements could include technical areas such as the sound system, human factors [11] such as mood, and context influence factors such as the listening environment.

By taking all of these factors into account, OLE [12] can be used to see if what effect technical factors have in real-world environments. One of the interesting elements of this is the role that audio quality [10] plays in OLE. Research has shown that the lower the audio quality, the lower people rate their Overall Listening Experience.

There is plenty of evidence that links QoE and improved business performance, particularly in the retail space [13]. In addition to this, background music is cited [14] as one of the main factors that helps to define the QoE in retail.

With this in mind, it is logical that retailers and hospitality venues should also be looking at the quality of their background music systems as part of a wider strategy to enhance customer experiences. With research linking QoE with business performance and the parallel measure for QoE in audio, OLE, showing that higher quality audio leads to a better experience, it follows that investing in a high-quality commercial audio system will be one way to help the overall business performance.

It is widely understood that audio performance is only as good as the weakest link in the signal chain. This would suggest that to see the full benefit in OLE and QoE, sensible investment should be made throughout the signal chain. This starts with a high-quality source that plays music at the maximum possible bandwidth and ends with professional loudspeakers, such as Martin Audio’s ADORN family.

The award-winning ADORN series of on-wall and ceiling loudspeakers bring class-leading performance, reliability and cost competitiveness to a wide range of commercial sound installations — from retail outlets, bars and restaurants to corporate offices. They have been created with audio quality as a top priority and as such can help businesses improve their OLE.

Summing up, Dom Harter, Martin Audio Managing Director, remarked: “Background music systems have not always been at the top of the priority list with retail, hospitality or commercial installations. However, the overall pattern of the research points towards this being a mistake. Making sensible investment decisions in your commercial audio system will help improve the overall listening experience for your audience. This, in turn, will help you to see the full benefits that music can bring to your premises, uniting your patrons. And with ADORN in plentiful supply, you don’t have to be waiting ages to make that change.”

LEA Amps Power Performing Arts Theater in Pilsen, Czech Republic : Alfa Theater

LEA Amps Power Performing Arts Theater : Alfa Theater

Alfa Theater in Pilsen, Czech Republic is a very well known performing arts theatre that specializes in the artform of puppeteering. When they chose to upgrade, they needed an audio amplification system that was flexible, powerful, and shipped on time to accommodate their busy schedule. They chose LEA Professional.

Let’s dive in!

THE SPEC

LEA AMPS POWER PERFORMING ARTS THEATER : ALFA THEATER

🏢 Venue: Alfa Theater | Pilsen, Czech Republic

👷‍♂️ Integrator: Audio Kropik

🎶 Audio Spaces: Main Theater

🦈 Product Used: CONNECTSERIES  CS354D (2), CS704D (1)

THE VENUE

Audio Kropik based in the Czech Republic is the largest seller of AV equipment in the South Bohemia region.

THE INSTALL

LEA AMPS POWER PERFORMING ARTS THEATER : ALFA THEATER

AudioMaster CZ initially received a call from the theater’s sound engineer explaining that they were having trouble with their system and needed them to work on a complete new system design. The team then worked with Jan Zvánovec, from Audio Kropik, the largest seller of AV equipment in the South Bohemia region, to bring the design to life.

“The theater’s sound engineer was having big issues with their existing system,” said Jan Zvánovec, Project Manager, Audio Kropik. “We met him on site and discovered that they had speakers that were not working and older amplifiers that were deteriorating and beyond repair — the system had simply reached its end of life.

The team began searching for system components to fit the theater’s requirements and limited budget. A critical specification was to find high-quality, multi-channel, audio-network-ready amplifiers that were affordable but could also deliver the power needed for the theater.

“I had not used LEA amps before, but they seemed to have all the features we were looking for, at a good price, and they were available,” said Zvánovec. “The amp’s cloud technology, built-in DSP, and the preset features were also very interesting; I wanted to see what these amps could do.”

The team upgraded the theater system with a set of three Dante Connect Series amplifiers. Two LEA CS354D, 4-channel amplifiers are used to power the upper and lower, left, right, and center main speakers, and an LEA CS704D 4-channel amplifier is used to power the system’s subwoofers. The new system comprises a mix of nine JBL AE Compact Series loudspeakers. A Yamaha DM2000 digital mixing console, equipped with a Dante network card, communicates directly with the LEA amplifiers via the Dante audio network protocol.

“The amps’ built-in Dante technology made for an extremely simple connection between the mixing room and technical room; everything worked on the first connection, and we have a lot of flexibility for easy, future upgrades,” said Zvánovec. “And there is also no need for external speaker processors because everything is managed by the DSP that’s built into the LEA amps. These features alone saved the client a lot of money and time.”

Using professional audio amplifiers with built-in DSP has become the standard practice for many AV system installers. DSP-powered equipment can do more with less, and therefore installers don’t need to buy, install, or maintain dedicated DSP equipment. Integrated DSP frees up critical rack space and reduces system weight. All the input routing, room tuning, speaker tuning, and limiting are built into the amplifier, so equipment racks are smaller, lighter, and cleaner.

“All the connectors and features of the LEA amplifiers are very logically arranged and well-engineered; the manufacturer thought of everything from the installer point of view,” said Zvánovec. “Setting up the amplifiers with a web browser is great, and we created several presets and stored them in the amps so the client can easily change the settings. Finally, no complicated installation and setup of applications; it was all very quick and easy.”

THE CONCLUSION

LEA AMPS POWER PERFORMING ARTS THEATER : ALFA THEATER

With many AV manufacturers having supply chain issues and ultimately not having products available, Alfa Theater realized thy only had a small window to finish this project to maintain their busy show schedule uninterrupted.

“Upon first hearing the new system, the client was extremely impressed in that the system sounded so much clearer and better than they had expected; this is thanks not only to the new speakers but also thanks to the powerful, natural sound of the LEA amplifiers,” added Zvánovec.  “I’m glad we had this opportunity to learn about and try the LEA amps; we’re definitely adding LEA to our list as a preferred amp supplier for future projects.”

We would like to thank both Audio Master CZ and Audio Kropik for choosing our amps for this killer installation and we hope that the audio systems will continue to deliver reliable audio for the audience at the Alfa Theater for years to come.

Onehunga High School Case Study

Onehunga High School was established in 1959 on its Pleasant Street site, situated in one of Auckland’s oldest suburbs overlooking the Manukau Harbour. Many families have long histories in the area and have many second or third-generation students. This gives the school a strong sense of tradition and
continuity. In addition, Onehunga High School is committed to providing lifelong learning for the community. As the college looks forward to equipping pupils for life in the 21st century, they require transformative audio, visual and control system updates.

An audio solution for two new state of the art teaching blocks was required. The first, a two basketball court gymnasium with exercise room, locker rooms and teaching spaces. And the second a new technical block catering to the sciences, woodwork, metalwork, art and two commercial-grade kitchens. An atrium space in the technical block also hosts school functions including catered meals where guests can be seated at tables and served directly from the kitchens.

In teaching areas with suspended ceilings, HH Electronics TNi-C4 ceiling speakers were used to provide quality sound while offering a budget-friendly solution. The TNi-C4 is a 4” coaxial speaker with a fully enclosed backcan with ported enclosure extending the low- frequency response over that of a non-backcan version.

onehunga 3

To maintain audio continuity, the TNi-W4 surface-mount version of the speaker was used in areas where there was no ceiling and the services exposed. The two-piece mounting bracket ensured quick and simple installation.

ITL Technologies, a company with more than 25 years’ experience in delivering quality data and networked solutions won the AV contract, and this experience would enable Onehunga High School to deliver a top- notch learning environment for students and guests.

MLA AGAIN BOWLS OVER SOUTH FACING AUDIENCES

Following the success of the inaugural South Facing Festival at the Crystal Palace Bowl last year, Festival Director, Marcus Weedon, requested the same formula for this year’s 10-day event. And that included Martin Audio’s ground-breaking MLA loudspeaker array, supplied once again by Capital Sound (part of the Solotech UK group).

This perfectly served the requirements of a top-class bill, including London Grammar, Bombay Bicycle Club, Jungle, Becky Hill and Richard Ashcroft.

Two other key developments helped boost the quality of the sound, as Solotech Project Manager David Preston—who was working alongside production manager, Julia Bruns, and site/production specialists, LS Events—explained. Driven by the excellent feedback, and absence of complaints from neighbours last year, he noted that levels within the bowl were raised from an SPL of 96dB(A) to 98dB(A) for this year, while the tech team still managed to stay within offsite thresholds.

The second advantage for Solotech was the extended space on the floating platform which housed the stage. Last year a lack of space at the front precluded mounting a broadside MLX cardioid subwoofer array across the front.

But with no such problems this year, 10 MLX subs were arced across the front of stage, with MLA Compact enclosures deployed as frontfills. David Preston explained: “Having the extra couple of metres along the front of the pontoon meant that we were able to get to a broadside cardioid array and provide more even sub coverage across the venue, and this also gave us greater control in the lower frequencies.

“The event is in a natural amphitheatre which seems to really help us with the audio coverage; the clarity at the back was similar to that at the front—which was great. As for MLA Compact, these provided a more robust option for front fills and could throw effortlessly across the nearby pond to hit the front of the audience.”

Preston led a Solotech team comprising Rayne Ramsden (System/FOH Tech), Isabella Di Biaise (Monitor Engineer), Harry Garcia and Diego Ternivasio (Stage Techs).

Ramsden programmed the DISPLAY software so that the sound tapered off at the site perimeter, thereby ensuring minimum bleed and maximum containment.

Once again, MLA was a hit with visiting sound engineers, among them Richard Ashcroft’s sound engineer, Al Davies. He has been using the PA since shortly after its launch over a decade ago, when with girl group Neon Jungle he said it was the best sound he had ever heard in Brixton Academy.

At Crystal Palace, despite the mix position being off axis he said the sound was balanced, the coverage even throughout, and the rear rejection impressive, with no backstage bleed. The subs also sounded great and non-granular. “Some have a tendency to sound ‘notey’, but the bottom end was balanced beautifully.”

He added, “Richard likes to be loud, so I was mixing at 97.5dB, almost up to the threshold, without ever struggling. He was really impressed and congratulated me afterwards.”

In conclusion, David Preston stated that Crystal Palace is now becoming one of the favourite festival sites he looks after during the summer calendar. “It’s a great space for concerts,” he said. “Working with Julia and the LS Events team is always a pleasure, and I look forward to 2023.

“Martin Audio’s MLA proved yet again that—noise control wise—it can do things that no other box on the market is capable of. For suburban festivals, with tricky noise limits set by local councils, that’s the important factor, to ensure the license for the festival can be granted again for the following year.”

WPM LINE ARRAY TOPS EBV’S INVESTMENT IN MARTIN AUDIO

German technology service provider, EBV Veranstaltungstechnik, has invested in Martin Audio’s Wavefront Precision technology, with the purchase of a WPM line array from territorial distributors, Audio Technica Deutschland.

Based in Hettenleidelheim in the Rheinland-Palatinate, EBV is a family business with a long tradition. Elmar Breitwieser founded the company over 40 years ago and focused primarily on regional musical events, which he initially equipped with sound and lighting systems before adding stage technology.

In 2018 Christian Breitwieser, son of the founder, took over the company and expanded the business from concert and festival events to corporate functions, conferences and more.

THE OPTIMISATION OPTIONS MAKE THE SYSTEM FEEL AT HOME ANYWHERE—WHETHER IN A ROCK CONCERT OR AS A SPEECH REINFORCEMENT SYSTEM.

Christian Breitwieser, EBV Veranstaltungstechnik

Needing to adapt and upgrade the audio equipment to the new requirement he opted for Martin Audio, stating, “I had already been familiar with the brand for a long time.”

His interest was rekindled, first when he became aware of the DD6 and CDD-LIVE series, and he initially expanded the company’s hire inventory by adding these two series, complete with a combination of SXP118 and SX118 subwoofers.

Justifying the purchasing decision, he said, “Both series have an asynchronously radiating horn—even as a self-powered coaxial system in the CDD-LIVE. The resulting performance is outstanding, the systems work very homogeneously and still sound extremely pleasant even at higher levels.

At the same time, he had also planned an investment in a line array, but this had to take a back seat due to COVID. “Fortunately, we now have a large number of events once again where a line array is needed. And for that reason we made an immediate decision to go with the WPM.”

Like the other members of the Wavefront Precision family, the smaller 6.5″ WPM system offers scalable resolution and very precise control capabilities thanks to the DISPLAY optimisation software. “The WPM fits perfectly into our portfolio due to its flexibility, EBV’s managing director continues. “The optimisation options make the system feel at home anywhere—whether in a rock concert or as a speech reinforcement system.”

An additional benefit of investing in Wavefront Precision had been its immediate availability, he confirmed. “We decided to make this investment at short notice in April and were pleasantly surprised that Martin Audio were able to deliver within a few weeks. This meant that the` system was already in use by the beginning of June.”

SWG EVENTS UPGRADE TO MARTIN AUDIO WPL

Long-standing Martin Audio rental partner, SWG Events, has upgraded its pro audio inventory with the acquisition of 24 of the large format Wavefront Precision WPL enclosures.

These form part of a Martin Audio package, along with 12 SXH218 subs and 24 XE500 floor monitors. Powering the WPL in 2-box resolution are Martin Audio iKON iK42 process-controlled, multi-channel amplifiers, part of an order for 17 iK42’s, which will also be assigned to the XE500.

Stated SWG Events’ Head of Audio, Simon Purse, “Everything came along at the right time, with me joining the company [from Martin Audio]. This coincided with SWG looking to buy a bigger, state-of-the-art system as an upgrade for their trusty W8LC, to put us back at the top end of the touring market, with higher tier acts.”

The acquisition was sanctioned by SWG managing director, Alister Pook, in light of the fact the company had been forced to cross-hire during this summer’s crowded outdoor season. “SWG has always been a Martin Audio house, and the fact that they were able to supply immediately from stock, plus our familiarity with the system, were major selling points,” stated Purse.

On arrival the new system was deployed within 48 hours, enabling their sub-hired MLA to return to base. This was at the Rhyl Event Arena for a package show that featured James, Tom Grennan and Jack Savoretti. It then moved onto CarFest North on the Bolesworth Castle in Chester.

Purse said that the choice of system size ticked a number of boxes. “A 12-box hang per side generally fits where we are at, giving us coverage for 5,000 up to 10,000-cap venue sizes.

“The Southwest has now got to the point where there is local availability to cross-hire so that we can scale up to a full arena system.”

He said he was particularly pleased with the XE500. “I believe we are one of the largest stockists of the XE500 and I’d be happy to put these in front of anyone.”

In conclusion, Martin Audio UK sales manager, Peter Codron added, “SWG has been a loyal, and long-serving customer of Martin Audio for many years. Their ongoing support is further reflected in this latest investment in our new technology, and being part of the ever-increasing UK Wavefront Partner Network. It is also gratifying to know that they already have a number of events earmarked for WPL.”

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.
