Quick Start
1 Ensure your safety First read and understand the Important Safety Instructions printed earlier.
Make sure that all your equipment is set for your local mains supply voltage and correctly grounded to
ensure your safety. Check that the console rear panel ON/OFF switch is in its out position (off). Plug in
the mains power using the power cord supplied with the console. Do not turn anything on until you
have checked your wiring and control settings. Also make sure the ventilation slots are not obstructed
in any way.

have checked your wiring and control settings. Also make sure the ventilation slots are not obstructed
in any way.
2 Set all controls to their starting position Set the AB levels, channel FADERS, GAINS, FB, AUX
and FX sends, MONO OUT and 2TRK to LR level controls minimum (anti-clockwise). Set PAN and all
EQ controls centre. Set all switches up or out. Make sure the 48V switches next to the MIC inputs are
in the up position. Check that the recessed panel switches are up (flush with the panel). Use a pen or
pointed object to operate these. Starting with the controls set in this way prevents any unexpected
surprises when you switch the system on.

3 Configure the system Decide how you wish to use the A and B main outputs. These would
normally feed amplifiers or powered loudspeakers. Set the A and B source switches for stereo , mono
+ monitor, or 2x monitor operation. These switches are recessed to avoid accidental operation once
set. A good starting point is the default stereo operation (both switches up).

4 Connect the amplifier/speakers Check that the loudspeaker cables are correctly connected at
the speaker end. Make sure the amplifiers are turned off and their level trims are turned fully down.
Connect the A and B XLR outputs to your amplifier or powered loudspeakers.

5 Plug in a music source Plug a CD player or similar test source into the ST3 inputs on the last
stereo channel. Check that the recessed switch below its GAIN control is flush with the panel. This
routes the ST3 input to the stereo channel.
routes the ST3 input to the stereo channel.
6 Turn the system on First switch on the CD player. Then press the PA rear panel ON/OFF switch
to apply power to the console. The front panel blue power LED lights. The meters and several other
LED indicators may pulse as the power rails stabilise. This is quite normal. Finally, switch on the
amplifiers or powered speakers. Always remember to turn the amplifiers on last and off first.

7 Adjust the levels and route the signal to the outputs Press the stereo channel PFL button.
Adjust the ST3 GAIN control until the main meters read around ‘0’. Release PFL and raise the channel
and LR faders to their ‘0’ positions. Set the A and B LEV trim controls to maximum. Now gradually
raise the amplifier level trim controls. You should hear the music in the speakers. With the meters
averaging ‘0’ to ‘+6’ adjust the amplifier controls for the loudest volume you expect from the system.
That gets the gain structure about right. You can adjust the A and B controls for normal listening level.

8 Experiment with the system Use the music source to experiment with the EQ and internal
effects. Plug a microphone into one of the mono channels. Make sure the channel is muted when you
plug or unplug microphones, or when you switch 48V phantom power on or off. To find out more
about each control continue to read through the rest of this guide. HAPPY MIXING !

Important Note about Hearing :
To avoid damage to your
hearing do not operate any sound system at excessively high volume. This
also applies to any close-to-ear monitoring such as headphones and IEM.
Continued exposure to high volume sound can cause frequency selective or
