Connection
Before connecting to amplifier, speakers or other equipment, turn down all volume controls to avoid loud noises which may
cause damage to other equipment. Always switch amplifier power on last in line with volume levels down.
Using good quality 6.3mm jack or XLR leads (balanced or unbalanced), connect L + R MASTER outputs from the mixer to the
amplifier, recorder or whichever equipment is to receive the main mix output.
If phantom power is to be used, switch in the PHANTOM on the rear panel
Connect microphones, DI boxes and other balanced low impedance audio inputs to the mono channels using a quality XLR lead.
Connect high impedance and line level signals to the mono inputs using a 6.3mm jack lead.
For stereo channels, connect left and right line level signals via 6.3mm jack – use left only for mono signals.
An additional 2 TRACK input is provided for playback devices on stereo RCA connectors and recording equipment can be
connected via the “REC” outputs using a twin RCA lead
The 6.3mm jack AUX SEND can be connected to monitoring or external processing equipment if required and the output of
external processing equipment can be brought back into the mix by connecting it to AUX RETURN.
For monitoring, headphones can be connected to the 6.3mm stereo HEADPHONES jack.
For CLP models, connect speakers via the LEFT and RIGHT Speaker Outputs on the rear panel, ensuring that the combined
load on each channel is no lower than 4Ω and the speakers are capable of the amplifier’s rated output.
With all faders down, connect the supplied mains lead to the mains supply and IEC inlet (ensure correct supply voltage). Switch
POWER on and the power LED will illuminate (if phantom power is selected, this LED should light also)

Set all HIGH, MID, LOW and PAN controls to the mid position (12o’clock) and AUX/DSP controls fully left (-∞)
Test each channel’s gain level by pressing in the PFL (Pre-Fade Listen) switch. If any PFL switches are on, the VU meters will
display the output of the PFL channel(s) instead of the overall output.
Make the loudest expected sound through that channel and increase the GAIN control until the signal reaches the 0dB mark.
Dynamic attacks, like the strike of a drum or pluck of a string, may be allowed to go into the amber coloured LEDs (up to +7dB)
but the red LEDs (+10dB) represent clipping, which should be avoided.
Once the GAIN is set, switch off the PFL for that channel and repeat the process for all other input channels.
Test the main mix output by gradually increasing the MASTER faders and selected channel faders whilst making sound through
the channel(s) – the L + R output LED ladders should begin to show the output as it varies up and down. Output will be heard
through any connected headphones or speakers.
Operation
Each channel has a 3-band EQ (LOW/MID/HIGH), which can be used to balance the mix of frequencies and emphasise certain
aural characteristics in the signal. Adjust these as required, noting that and overall increase may require an equivalent reduction
of the GAIN control to compensate (otherwise clipping may occur from EQ boost).
An individual PEAK LED on each channel helps to show if any channel input is clipping.
Use the PAN control to position the channel input either to the left or right side of the stereo field. This can be useful to help
separate and define sounds within a mix but be aware that extreme settings can be counter-productive by removing the channel
from certain listening positions.
Use the AUX control to feed the correct amount of the channel signal to the AUX SEND. The combined AUX SEND level from all
channels is governed by the AUX SEND rotary control. Likewise, the AUX RETURN rotary control determines the level fed back
into the mixer via the AUX RETURN jack. Adjust AUX SEND so that its output does not overload connected equipment and
match the level brought back with the AUX RETURN control.
Each channel has a DSP control which feeds a portion of the signal to the internal DSP (Digital Signal Processor)
The internal DSP section can provide one of 16 internal effect types, as listed below…
Each effect has a particular adjustable setting which can be altered, changing the nature of the chosen effect program. These
are listed in the table above and the best setting can be found for each by experimentation with the DSP PARAMETER control.
Overall DSP effect level fed to the mix is controlled via the DSP fader.
There is also a 2-TRACK fader to adjust the level of the signal fed in via the 2-TRACK RCA inputs.
Channel faders should be used to adjust the individual levels in the mix and the MAIN fader is for overall level.
Turn down MASTER levels when changing any connections or powering down the mixer to avoid speaker damage
Troubleshooting
No power LED on control panel
Ensure power lead is in good condition and connected properly
Ensure mains outlet voltage is as stated on adapter
Check internal fuse – if blowing fuses, refer to service personnel
Power LED is on but no other LEDs and no output
Check input signals and condition of connection leads
Check GAIN is not too low on channel input
Check channel fader, GAIN and EQ controls are not turned fully down
Check MASTER faders are not fully down
For condenser mics, turn down MASTER faders and check phantom is on
Check that PFL buttons are all switched out
Check that all Graphic EQ sliders are not fully down
Power light and VU LEDs lighting but no output
Check output connections to amplifier, recorder or speakers
Check amplifier or recorder levels are not turned fully down
Check that PFL buttons are all switched out
No output from stereo channels
Check that mono input is connected to L/MONO jack
VU LEDs do not show MASTER output level
Check that PFL buttons are all switched out
Output is very loud or distorted
Check level of input signal is not too high
Reduce channel GAIN and EQ settings
Reduce channel and MAIN faders levels
Ensure Hi-Z line level input(s) not connected via XLR
Check output levels of equipment connected via channel inserts
Check AUX and DSP level controls and reduce if necessary
Check input gain level on recorder or recording software
Output is working but at very low level
Check input audio source level is not too low
Ensure low impedance line or mic signal is not connected via jack
Increase channel GAIN control and EQ settings if turned down
Increase channel and MAIN faders levels
Check input gain level on recorder or recording software
Feedback (loud squealing or howling from mics)
Face microphone away from speakers and monitors
Reduce channel GAIN level and EQ level(s)
Reduce AUX and/or EFFECT levels
Reduce channel and/or MAIN fader levels
Note: for further troubleshooting, refer equipment to qualified service personnel for testing
