Description
This amplifier kit is designed to feed a single audio zone and provide a 24 Vdc visual notification appliance circuit. The amplifier provides four Class B audio output circuits that are compatible with 25 or 70 Vrms speakers. An optional Class A card can be installed where redundant speaker circuit wiring is required. Each amplifier is equipped with a backup amplifier circuit, which automatically switches on if the amp circuit fails. Customers with larger systems may want to consider installing separate cabinets to house the kits throughout their buildings to reduce the wiring required for installation, and to lessen the chances of audio signal degradation.
