The SPA amplifiers are primarily designed for integration into Voice Alarm systems, but thanks to its flexibility, it can also be used for any Public Address or Commercial application. SPA amplifiers are certified to the EN54-16 standard.\nThe SPA are 2U high 19 rack mountable, 2-channel power amplifiers. Transformer isolated for 100 V, 70 V and 8 Ohm low-impedance distributed loudspeaker systems.\nThe SPA can be powered by either a 220 VAC mains supply or 24 VDC supply able to support a battery back-up system for use in the event of mains failure and emergency evacuation systems.\nSPA amplifiers have short-to-ground, short-circuit, overload and temperature overheat protection including line-impedance surveillance with a maximum of 5% deviation using the DIVA8 or IDA8 systems for loudspeaker-line surveillance. They support both single spur and redundant loop (A/B) cabling. |
