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 suited for those applications that require automatic switching and amplification. The DPA-1.

4. FRONT PANEL Power Switch: Turns on the main power for the amplifier. When the power is on, the LED will be illuminated. 5. BACK PANEL CONNECTIONS LINE INPUT SENSING Line Input: This line input is a sensing input that will activate the DPA-1.2 L when an audio signal is present. When there is no audio, the amplifier will go into standby or default back to the R whole-house amplified signal if playing. Speaker Level Input: The speaker level input is a sensing input that will automatically switch the DPA1.
Speaker Outputs: The A and B speaker outputs are in parallel to the amplifier output. When connected to the A or B output, either 6ohm 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.
6. SPECIFICATIONS Audio power output: Continuous 35W @ 8 Ohms, 45W @ 6 Ohms. Frequency response: 20HZ to 20KHZ -0.3dB. Total harmonic distortion: 0.05% 8 Ohm .075% 6 Ohm Input sensitivity: 400mV line Input impedance: 22k Line Input Signal to noise ratio: 85dB Input trigger: 12VDC 10k Output trigger: 12VDC 100mA Auto off delay time: 2 to 10 minutes Primary fuse: T2.0A /250V Power requirements: Factory set for 120 VAC 60Hz or 230 VAC 50Hz.
7. WARRANTY The Russound DPA-1.2 is fully guaranteed for two (2) years from the date of purchase against all defects in materials and workmanship. During this period Russound will replace any defective parts and correct any defect in workmanship without charge for either parts or labor. For this warranty to apply, the unit must be installed and used according to its written instructions. If service is necessary, it must be performed by Russound.
