Please read the following warnings and tips before hooking up your DMA-1240/DMA-1275:
- Never connect speaker wire or line level connections with the front power button in the ON (in) position. Always make
your connections with the amplifier OFF.
- Only use the detachable power cord supplied with your DMA-1240/DMA-1275. It is a 3-prong, grounded power cord.
- Never disable the ground wire in the power cord. This is for your protection.
- Never plug the DMA-1240/DMA-1275 into the back of another electrical component.
- We highly recommend plugging the DMA-1240/DMA-1275 into a power tree with adequate surge protection.
- Dual banana plugs with industry standard 3/4” spacing (sold separately) will fit the speaker connections in each individual
channel, but will not fit across the two red posts when operating side-by-side channels in bridged mode. We offer single
banana plugs (sold separately) for this purpose.

The DMA-1240 (DMA-1275) is a 12-channel, multi-use, multi-zone power amplifier that is flexible and powerful enough to
amplify every speaker in your whole-house audio system and/or home theater system. This amplifier delivers exceptionally
accurate sound and is designed to deliver trouble-free performance for many years to come. Each channel delivers 40
watts RMS (65 watts RMS for DMA-1275) into 8 ohms and 50 watts RMS (100 watts RMS for DMA-1275) into 4 ohms
with all channels driven. In addition, you can choose to bridge adjacent channels (eg. 1 and 2) to create a single 100 watt
RMS (150 watts RMS for DMA-1275) channel. This allows for a multitude of set-up options for virtually any application that
requires multiple discreet channels of amplification.
This owner’s manual is designed to get you quickly up and running with your new system. Should you have any questions,
