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
