2. INTRODUCTION Congratulations on your recent purchase of the Russound DPA-1.2 two-channel amplifier. The DPA-1.2 is a high-current, high-quality amplifier, which includes automatic A/B switching. The DPA-1.2 two-channel amplifier will amplify a source at the sensing line input or the sensing speaker level input. Switching between a default audio source and a local source, the DPA-1.2 is ideally suit- ed for those applications that require automatic switching and amplification. The DPA-1.2 powe

Speaker Outputs: The A and B speaker outputs are in parallel to the amplifier output. When connected to the A or B output, either 6- ohm or 8-Ohm speakers could be used. When using both A and B speaker outputs, only speakers with impedance higher than 8 Ohms can be connected. For Bridge amplifier operation, connect the + of the speaker to the R+ and - of the speaker to the L+ of the amplifier.

12-Volt Trigger In and Out: The Trigger 12V 12V TRIG TRIG output is 12 volts at a maximum of OUT 100mA INPUT 100mA. This can be used to drive a relay- operated AC outlet or other 12-volt triggered devices. The 12-volt trigger input is used to activate the DPA-1.2 independently from the auto turn on sensing circuit, in which case the delay, video and audio sensing are bypassed. Delay Time: The delay timecan be adjusted from about DELAY 5 1 0.3 minutes to 8 minutes. The DPA-1.2 amplifier will 4
