The Russound ADP-1.2 is a passive interface that turns a speaker-level signal into a line-level signal, letting you take the speaker output of an amplifier or receiver and feed it into the RCA inputs of a separate, more powerful amplifier. Russound designed it for the CAA66 and MCA-66 controller amplifiers, where some zones have no preamp outputs; the ADP-1.2 provides the line-level feed those zones are missing, so a zone can drive a high-power amp for larger rooms, more speakers or a subwoofer. The input side uses color-coded, detachable snap connectors that take up to 14-gauge wire without screws, which makes hookup quick in a crowded rack. Output is on RCA female jacks. The adapter applies 30 dB of attenuation and is rated to handle 250 watts per channel RMS continuous, 500 watts per channel peak. Russound advises against using it with digital amplifiers, so check the source amplifier's design before installing.
