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.
