Product Description: The MPSS-4 is a multi-purpose source switching device that can be used for switching between two 4-channel RCA (stereo front/rear) sources. For example, you can switch between a cassette receiver and a CD receiver. You can also use the MPSS-4 to add an auxiliary source when there is no auxiliary input on the existing head unit. Note: Use of the MPSS-4 requires an audio system with a 4-channel amp or two 2-channel amps.

Application 1: The MPSS-4 allows you to connect two source units, each with their own amplifier trigger lead (example: cassette head unit and CD head unit). When properly connected, Source 1 will automatically turn off when Source 2 is turned on. Conversely, when Source 2 is turned off, Source 1 is automatically turned on. Line-level audio from each source is input to the switcher, and the audio output from the selected source goes to a single 4-channel amplifier (or two 2-channel amps). You can also output the audio through an EQ or crossover before the amplifier.

Application 2: You can connect two source units to the MPSS-4, even if only one source has an amplifier trigger lead (example: head unit and auxiliary source such as DVD, VCP, MP3, Game, etc.). When connected, Source 1 audio and/or power will turn off when Source 2 is turned on. Line-level audio from each source is input to the switcher, and the audio output from the selected source goes to a single 4-channel amplifier (or two 2-channel amps). You can also output the audio through an EQ or crossover before the amplifier.

Connections: The input side of the switcher features four pairs of gold-plated RCA jacks: Source 1 Front L-R/Rear L-R and Source 2 Front L-R/Rear L-R. There are also 5 wires for power, ground and switching (red, black, orange, gray, yellow). The output side of the switcher has 2 pairs of gold-plated RCA jacks: Front L-R output/Rear L-R output. There is also a blue amplifier trigger lead on the output side.
