The DAA2 series amplifiers are multi-featured digital audio amplifiers capable of playing up to two of 8 channels of digital audio; can play up to two different messages simultaneously with the optional BDA amplifier. Each DAA2 amplifier includes a firefighter/emergency telephone riser circuit and remote paging microphone circuit. The backup digital amplifiers provide an economical means of backing up DAA2 and DAX amplifiers in a one-to-one primary/backup configuration. A BDA can also provide a second audio channel for a DAA2 when programmed as a primary amplifier in VeriFire Tools. A BDA is not addressable it is considered a part of the digital amplifier to which it is attached. The BDA may be programmed and wired for backup or for providing a second audio channel.
