The Sonance Professional Series PS-60XF Transformer matches the impedance of any 8 Ohm Sonance speaker (or other 8 Ohm or 4 Ohm speaker) for 70V/100V system configurations. The PS-60XF has multiple input taps for different wattage requirements. 

Use this product in projects where a Sonance 8 Ohm speaker is desired but the system is comprised of other 70V/100V speakers on a 70V/100V amplifier. These system configurations are typical of applications where many speakers are connected to a single amplifier for coverage in large areas or where speaker placement is over a great distance, requiring long speaker wire runs. 70 volt systems are great for commercial applications such as restaurants, hospitality, and amusement parks but are also frequently used in residential outdoor applications. They are ideal for covering large areas and maintaining a consistent volume level.
