qtx MM41 4 Channel Mini Microphone Mixer
OVERVIEW
Thank you for choosing the QTX mini mixer series as part of your audio system.
These convenient, compact units are designed to provide a useful solution for
combining several mics or line signals into a single sound system.
Please read and keep this guide to help get the best results and avoid damage
to your mini mixer. NThe QTX mini mixers can be powered by a 9V battery or an
optional 12Vdc power adaptor.
To insert a 9V PP3 battery, unscrew the cover on the base of the mixer,
connect the battery clip and replace the cover. Alternatively, connect a 12Vdc
200mA (min) adaptor to the rear DC input, ensuring the correct polarity. With
the power switched off at the rear and all volume controls turned down,
connect all inputs via a 6.3mm jack. MM41 and MM81 models have inputs to match
microphone level. LM41 and LM82 models require line-level inputs.
All inputs will be mixed to a single output except the LM82 mixer, which feeds
4 inputs to each of 2 outs for stereo. Connect the output jack(s) to the sound
system or recording device. Switch the power on and turn up Master Volume part
way. The power LED will illuminate. Increase each input channel volume in
turn, checking the level through the connected equipment. When all inputs are
balanced as required, adjust the Master Volume to the required level. Ensure
that the red LED beside the Master Volume control does not light other than
momentarily. If this LED stays on longer than this, reduce the Master volume.
