Introduction
The MicroMixer 18 is an expansion of MIDIMAN’s MiniMixer
and FineLine concept of “mixing at the source.” This new
concept offers many advantages over the traditional mixing
console such as smaller size, lower cost, greater headroom
and less noise.

Mechanical Assembly
In the small plastic bag in the MicroMixer box, you will find
four rubber feet, two threaded knurled knobs, two 1/4”
8/32 machine screws and two 1/2” 4/40 machine
screws.
The MicroMixer can be configured as either a tabletop or
rack mount mixer. For tabletop use, simply attach the rubber
feet to the bottom corners of the unit.
For rack mount use, replace the two outside screws on the
very front of the unit with the two 4/40 knurled knobs and
use the 1/4” 8/32 screws to attach the unit to a standard
rack tray (if you can’t find one, contact MIDIMAN). You can
then use the knobs to slide the mixer in and out of the rack
when you need to change settings.
WARNING!!! USING A
LONGER SCREW WILL CRACK THE CIRCUIT BOARD AND
VOID YOUR WARRANTY!
If you are rack mounting the unit and need to lock the
MicroMixer securely in place (preventing it from sliding forward) you can use the 4/40 machine screws provided to
screw through the back of the rack pan and into the
MicroMixer itself.
Overview
While reading the following description of how the
MicroMixer works, it may be helpful to refer to the Front &
Rear Panels - Figure 1 on the preceding page, or the Block
Diagram - Figure 3 located in the back of this manual.
Inputs
The MicroMixer has 12 inputs with gain control, pan control,
two sends per channel and an LED clipping indicator. These
inputs provide up to 20dB of gain. The remaining six channels (numbered 13 through 18) are configured as three unity
gain stereo pairs with inputs 14, 16 and 18 going to the
