Operation
Ensure that amplifier(s) or active speaker(s) are switched off before powering up the ML432 mixer.
Switch on the power and the Power and Normal LED indicators should light (7)
Now switch on power to the amplifier or active speaker(s) and turn the volume(s) up part way.
Turn up the Left and Right output controls (4) half-way.
If connected, speak into a microphone whilst gradually turning up its channel level control (1)
If no microphones are connected, play a line level signal into a channel whilst gradually turning up its level.
The L+R output meters (5) should light up and the sound should be heard through the connected speakers.
Increase the Left & Right output levels if required and set the channel level control to the required volume.
Repeat the above steps for all connected inputs whilst balancing levels between channels as required.
For the AUX inputs, a single rotary control for each (2) adjusts the level of both left and right RCA inputs.
Sensible use of the output meters (5) will help to avoid overdriving the outputs and/or connected amplifiers.
The +6dB LED should only light briefly on percussive or transient parts of the sound (i.e. bass drum)
If the +6dB LED is lit for any longer than short bursts, the level controls will need to be turned down.
This will avoid signal clipping and overdrive, which can be damaging to equipment connected to the outputs.
For overall tone adjustment, moving the Tone controls (3) up or down can help improve the sound quality.
If the sound is too thin sounding, turn up the BASS rotary. If it is too deep sounding, reduce the BASS level.
If the sound is not very clear, turn up the TREBLE rotary. If it is too harsh sounding, reduce the TREBLE level.
A CH.1 override function can be set to suppress all other channel inputs when a signal is present on CH.1.
Speaking into the CH.1 mic will suppress the output of MIC 2-4 and AUX 1-3 and the Priority LED will light (7)
When CH.1 is silent, the other channels will resume normal volume level and the Normal LED will light (7)
The amount by which this function mutes the other channels is set by a rotary control (15) on the rear panel.
This same function is active for the priority line and 100V inputs (13, 11).
Turn up the priority input level control to enable these inputs and adjust to the required volume level.
Turn down amplifiers or active speakers before powering down the ML432 mixer to avoid loud noises.
