2. INTRODUCTION
Congratulations on your recent purchase of the Russound DPA-6.12 12-channel amplifier. The DPA-6.12 high-
current, high-quality amplifier is the heart of the home theater or multi-zone system. The DPA-6.12 12-channel
amplifier is capable of amplifying six stereo line level sources (CD players, tape decks, preamplifiers, tuners, etc.)
simultaneously in multi-zone, multi-source installations. The twelve amplifiers are arranged in pairs to provide six
stereo amplifiers. With separate gain controls for each channel, sound levels can be preset to accommodate most
rooms. The Main Bus Input allows for two or more stereo amplifiers to share the same audio source. With the
stereo/mono selector in the mono position, two amplifiers can serve as mono outputs. In the mono position the
six stereo pairs can be bridged to three stereo pairs for higher output power. The DPA-6.12 power output is 50
watts per channel into 8 ohms, and 75 watts into 4-ohms. Bridged adjacent outputs provide 100 watts of power
into 8-ohms and 150 watts of power into 4-ohms. All this power is backed by two high output toroidal transform-
ers. Each amplifier output channel incorporates thermal, short circuit protection and Russound’s unique Dynamic
Clipping Sensor that allows for better headroom and volume without clipping or distortion that is normally heard
in most amplifiers.
The Russound DPA-6.12 amplifier is built with pride. Fidelity, reliability and quality are the primary objective.
Russound products are guaranteed to provide years of enjoyment.
3. POSSIBLE SYSTEM CONFIGURATIONS
The DPA-6.12 can be configured as an audio distribution system, or used as the main amplifier for a home the-
ater system. As an audio distribution amplifier each zone can independently drive several different sources by
using each of the individual line audio inputs for each of the zones. As a home theater amplifier the DPA-6.12
output can be bridged to provide high power out for the front channel while the remaining channels are used to
drive the surround effects.

This is a sensing input that will activate the zone when an audio signal is present. When there is
no audio the zone will go into standby.
LINE
Bus / Line Switch: Selects the Line audio input or the Main bus input for each

Bus input. When line is selected the zone will amplify the audio at the line
input for that zone.

Speaker Outputs: The A and B speaker outputs are in parallel to the amplifier output. When connected to the A or
B output either 4-ohm or 8-ohm speakers could be connected. When using both A and B speaker outputs, only 8-
ohm speakers can be connected, and this will result in a 4-ohm load at the amplifier. For Bridge amplifier opera-
tion, connect the + of the speaker to the R+ of the amplifier and - of the speaker to the L+ of the amplifer.

12 Volt Trigger In and Out: The Trigger output is 12 volts at a maximum of 150ma.
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 a zone independent from the
auto turn on sensing circuit. The delay and audio sensing are bypassed when the
12 volt trigger input is used.
