Notifier BDA-70V is a backup digital amplifier with a 70 VRMS output and switch settings for 50 W or 35 W operation. It mounts on a DAA2-50 or DAA2-75 series digital audio amplifier, where it can provide one-to-one backup for that amplifier or, when programmed as a primary amplifier, a second audio channel.
Notifier lists three configurations for an optional BDA: a backup amplifier for one-to-one backup on all DAA2 models, a primary amplifier for two-channel operation on all DAA2 models, and a primary amplifier that raises output to 100 W for one- or two-channel operation on the DAA2-50 series only, where configuration rules apply. The 70 V BDA-70V pairs with 70 VRMS DAA2 amplifiers; the BDA-25V is the 25 VRMS version.
