Usage diagram
Passive circuit design, no need for power supply, convenient to use, just connect all input and output audio devices to the interface of MC102,
just as the following picture shows:
MC102 is a 2-IN-1-OUT / 1-IN-2-OUT audio selector designed
for customers who have several audio sources and outputs,
2-IN-1-OUT suitable for debugging equipment and do audio
source contrast, 1-IN-2-OUT for headphone, power amplifier
and active speakers contrast. With A/B selector, volume control
and one key mute, very convenient to use.

1. MC102 is not compatible with turntables.
PHONO signal is to low so that the output sound will be low
and sound distortion will be generated, you can have a try but
we can't guarantee it will work normally with turntables.
2. MC102 cannot be connected to passive speakers directly.
For example, these connections are correct: audio source --
(preamplifier) -- MC102 -- active speakers, or audio source-
MC102-- amplifier --passive speakers.
3. We designed a new 3.5mm AUX interface on the right of the
other four 3.5mm AUX interfaces for some customers who
want to connect all cables at one side. But the input and output
of 3.5mm AUX interface on the opposite side is prior than the
new 3.5mm AUX interface.
4. The volume potentiometer only can work normally in
2-IN-1-OUT mode, the volume can be adjusted very smoothly.
While in 1-IN-2-OUT mode, the volume cannot be adjusted
smoothly by the potentiometer, especially when connected to
active speakers. But if you connect MC102 to headphones,
there is no such problem in both modes.
5. If there is static noise, it is usually caused by common ground
or empty load, just need to add an audio isolation module to one
of the active speakers/amplifier/preamp. For example,
MC102--isolation module--active speaker(1-IN-2-OUT mode),
or audio source--isolation module--MC102(2-IN-1-OUT mode).
