Initial set-up
Once you have connected up your system (see the sections on connection and wiring earlier in this manual for guidance) you are
ready to set initial positions for the controls on your mixer.
Set up individual input channel as follows:
Connect your sources (microphone, keyboard etc.) to the required inputs and release the MUTE switches. Note: Phantom
powered mics should be connected before the 48V is switched on.
Set Master faders at 0, input faders at 0, route the channels to MIX and set power amplifier level to suit the application.
Provide a typical performance level signal and press the PFL button on the first channel, monitoring the level on the
bargraph meters.
Adjust the input gain until the meter display is in the amber section, with occasional peaks to the first red LED at a typical
maximum source level. This allows sufficient headroom to accommodate peaks and establishes the maximum level for
normal operation (but see note below).
Repeat this procedure on other channels as required.
Listen carefully for the characteristic sound of `feedback’. If you cannot achieve satisfactory input level setting without
feedback, check microphone and speaker placement and repeat the exercise. If feedback persists, it may be necessary to
use a Graphic Equaliser to reduce the system response at particular resonant frequencies.
Note: The initial settings should only be regarded as a starting point for your mix. It is important to remember that many factors
affect the sound during a live performance, for instance the channel EQ settings or even the size of the audience!
You are now ready to start building the mix and this should be done progressively, listening carefully for each component in the mix
and watching the meters for any hint of overload. If this occurs, back off the appropriate Channel Fader slightly until the level is out
of the red segments, or adjust the Mix Master Faders. This procedure will ensure that the mixer is set up correctly, with adequate
headroom. If more amplification is needed, adjust the power amplifier level controls.
