MiniMix II features better than 0.004% total harmonic distortion and noise floor
along with an extremely flat frequency response covering 20Hz to 20 KHz. The
MiniMix II assures that your amp signal is not degraded by ADA converter in your
processor. Now you can play with the peace of mind that the pure guitar-amp
signal that you've worked so hard to attain is not compromised by suspicious
circuits in various effects units.
The MiniMix II adds new features to the original MiniMix with its ability to receive
signals from two separate processors in parallel, a control jack that allows you to
mute the dry signal for those effects patches (like compressor, chorus, tremolo or
EQ, etc.) that are better suited for series operation, and an isolated transformer
to eliminate ground loops. The MiniMix II now accepts both high-impedance
instrument level signal or low-impedance line level signal, making this an
invaluable addition to your rig.

Description:
The MiniMix II is an FX loop mixer that sums the amplifier dry signal to two
effects devices (via TRS jack). It utilizes a stereo control jack to turn on and off
the dry signal path as well as the FX path. It can also act mute the amplifier. FX
signals are transformer-coupled to eliminate ground loops.
The MiniMix II is powered by 9Vdc (preferable) or 9Vac. The plug used is a
2.1mm x 5.5mm plug. The plug polarity is irrelevant as the MiniMix II utilizes a
full-wave bridge for power input protection.

Connections for one processor or processor chain:

Feature Switch:
The feature switch re-routes the signal on the FX return jack. When the switch is
in the down position, the MiniMix II accepts one balanced input on the TRS jack.
When the switch is in the up position, 2 inputs, one on the TIP and the other on
the RING, are summed. Note that the shield is common between both inputs. A
standard insert cable can be used for this mode of operation. The insert cable
consists of 2 mono jacks tied to a stereo jack.
