DESCRIPTION

MICROMIXER is a four-input, two-output stereo mixer/combiner for utility use. The unit has

balanced bridging inputs for four audio sources (two stereo pairs) which can be mixed to two

outputs (one stereo pair). A level control is provided for each input. Selectable 'assign'

switching permits any input to be fed to either or both outputs. DC coupled circuitry provides

excellent sonic performance.

INSTALLATION

All connections to the MicroMixer are made via plug-in connectors. Remove about 1/8” of

insulaton, insert wires into the plug, and tighten the screws. Be sure that no bare wires are

exposed.

Audio inputs to the MicroMixer should be connected to the balanced input terminals labeled 1, 2,

3, and 4. For unbalanced inputs, install a jumper between the (-) terminal and G (ground). All

inputs are bridging; it is not necessary to terminate the source unless required by the source

equipment.

Audio outputs from the MicroMixer are connected to the two outputs labeled L (Left) and

R (Right). The output circuitry will drive any load of 600 ohms or higher. It is not necessary to

terminate the outputs. For unbalanced outputs, connect to the (+) and G terminals only. DO

NOT short the (-) terminal to ground.

OPERATION

The input levels to the MicroMixer should be between -10 and +8 dBm. Adjust each input

channel using the INPUT LEVEL controls. Unity gain is achieved with these controls set to 10

o'clock; with nominal input levels of +4 dBm the Input Level controls should be run near this

setting. It is recommended that input levels be initially set with a level indicator (VU meter,

scope, VOM) temporarily connected to the MicroMixer's output to monitor output levels. The

average output level should not exceed +8 dBm to ensure adequate headroom.

Each output channel (L & R) has four ASSIGN switches that determine which of the four input

signals are fed to that output. Select the input sources desired by switching the appropriate

channels ON (down). For example, if inputs 1 and 3 should be fed to the LEFT output, set Left

output assign switches 1 and 3 ON, with 2 and 4 OFF.
