Congratulations on purchasing the Gemini UMX-7 VCA mixer. This state
of the art mixer is backed by a three year warranty, excluding crossfader
and channel slides. Prior to use, we suggest that you carefully read all the
instructions.
With VCA technology, audio is processed in a voltage-controlled amplifier
(VCA) removing it from the crossfader and channel slides giving them
extended life and reducing travel noise. The crossfader and channel slides
regulate the DC voltage that controls the VCA circuit. Additional
advantages of VCA technology include the ability to provide precise curve
adjustments for the crossfader and channel slides without sacrificing audio
quality. For additional information, refer to the diagrams on Page 3 for
crossfader adjustment and channel slide curve.

When using a UMX mixer with professional turntables, such
as the Gemini PT Series, you can make the mixer level with
the turntable by removing the mixer's feet.
1 . Place a small screw driver under the foot's center anchor.
2 . Gently pry the center anchor up and the foot will come off.
To replace the foot:
1 . Place the foot on the mixer without the center anchor.
2 . Replace the center anchor and push down on it to anchor the foot to
the mixer.
