The Basics
operation
1. Set POWER to ON to turn on the mixer. To avoid popping sounds,
always turn on the mixer before you turn on the amplifier.
2. Turn on the output amplifier and leave its volume set to
minimum.
3. Set the audio input source’s volume to minimum. Turn on
the source, and set it to play (or continuously talk into the
microphone).
4. Adjust the mixer’s corresponding CHANNEL 1, CHANNEL 2, CHANNEL 3,
or CHANNEL 4 to
6-10. When mixing more than one audio input,
adjust each input’s volume to about the same listening level.
5. Adjust the output amplifier’s volume as desired.
6. When you are finished mixing, turn off the mixer, the output
amplifier, and all audio input sources.
mixing mono or stereo
To mix mono signals with stereo signals, set STEREO/MONO to STEREO.
When STEREO/MONO is set to MONO:
• The mixer routes monaural input signals of devices connected
(separately) to the mixer’s AUX 1 L, AUX 1 R, AUX 2 L, AUX 2 R jacks to
both outputs (AUX 1 L and R, AUX 2 L and R).
• The mixer changes stereo input signals of devices connected to
the mixer’s AUX 1 L/R and AUX 2 L/R jacks to monaural signals.
For mono amplifiers (found in some PA systems), it is best to set
MODE STEREO/MONO to MONO.
