Notifier DS-AMP is the 120 VAC Digital Series amplifier used with the DS-DB distribution board to add bulk audio amplification to a Notifier Digital Voice Command (DVC) system. It delivers 125 W at 25 VRMS, or 100 W at 70 VRMS with the DS-XF70V step-up transformer. Up to four DS-AMP amplifiers can be connected to one DS-DB.

Compatibility and installation notes
- Ships already installed on its chassis; mounts in one row of any EQ or CAB-4 Series cabinet. A DP-1B dress panel (ordered separately) can cover the CAB-4 row.
- The DS-XF70V step-up transformer mounts on the front of the amplifier for 70 VRMS operation and is ordered separately.
- Backup audio: add a DS-BDA or a dedicated DS-AMP. A DS-BDA backing up a 70 VRMS DS-AMP also needs a DS-XF70V.
