OUTPUT SECTION
1. AUX1 RETURN– 1/4" Jack Mono Socket Inputs
To inject the return signal from external effects back into the mixing
console. When a jack is inserted, the internal DSP-effects are not
used.
2. AUX2 RETURN– 1/4" Jack Mono Socket Input
Same function as Aux1 Return(1). Can also be used to connect an
extra sound source (ex. CD player) to the mixing console.
3. POWER LED
This blue led is lit when the power is switched on. (the power switch is
situated on the back of the mixing console)
4. LED VU-METER
This is a 12 segment led meter with VU calibration providing a signal
monitor range from –20dB to 6dB. with a change of colour at the
nominal 0dB position.
5. MASTER CONTROL FOR AUX1 SENDS
Used to set the general output level of the AUX1-signals, controlled
by the AUX1 FX Sends (11) and sent to the internal or external effect
processor.
6. MASTER CONTROL FOR AUX2 SENDS
Used to set the general output level of the AUX2-signals, controlled
by the AUX2 FX Sends (12) and sent to the external effect processor
(post-fade) or to stage monitors (pre-fade).
7. MASTER CONTROL FOR AUX1 RETURN
Used to mix the AUX1 return signal with the main output of the mixing
console.
8. MASTER CONTROL FOR AUX2 RETURN
Used to mix the AUX2 return signal with the main output of the mixing
console.
9. MASTER OUTPUT FADER CONTROL
Used to set the required overall output level to the power amplifier (or
other equipment). The calibration shows a suggested nominal running
level, referenced ‘0’ (10dB boost is available if required).
10. STEREO MAIN MIX OUTPUT - 3 pin Male XLR Sockets
Used to connect the master output (Main mix) of the mixer to a power
amplifier (or other equipment)
Output wiring:
11. AUX SEND OUTPUT – 1/4" Jack Mono Socket (unbalanced) output
Used to send the signal of AUX1 to external equipment or effect units.
Remark: When you insert a jack connector in the AUX1 SEND output, the internal effect unit
will automatically be deactivated.

12. AUX SEND OUTPUT – 1/4" Jack Mono Socket (unbalanced) output
Used to send the signal of AUX2 to external equipment, effect
units or stage monitors.
13. TAPE OUT – stereo RCA Socket Outputs (unbalanced)
The signal is derived from the main stereo output mix after the
output faders and can be used to record the master mix.
14. TAPE IN – stereo RCA Socket Inputs (unbalanced)
Signal is routed to the main stereo output before the faders
and the monitoring system.
15. TAPE MONITOR SWITCH
Used to select which signal is routed to the PFL-switch (16):
Switch ON (lit): signal from TAPE IN (14)
Switch OFF (not lit): signal from MAIN MIX. This is the
same signal as on the TAPE OUT (13) and the MAIN MIX
OUTPUT(10).
16. PFL SWITCH
Used to select which signal is routed to the HEADPHONE
output (19):
Switch ON (lit): PFL-signals of the input channels.
Switch OFF (not lit): signal is selected by the TAPE
MONITORswitch(15).
17. PLAYBACK SWITCH
Used to add the stereo TAPE IN(14) signal to the main stereo
output mix or not.
18. PLAYBACK LEVEL CONTROL
Used to set the playback level of the TAPE IN(14) signal.
19. HEADPHONE OUTPUT – 1/4" Stereo Jack Socket Output
Output wiring:
Minimum Load impedance: 40 Ohm
20. HEADPHONE LEVEL CONTROL
Sets the level of the HEADPHONE output (19).
21. DSP CLIP LED
This led blinks when the input signal of the internal DSP-effect
processor is too high.
22. EFFECT SELECTOR KNOB
Used to select one of the 8 available digital effects.
23. DSP TIMING KNOB
Used to adapt the selected effect to your personal taste.
24. DSP MUTE
When this button is lit, the internal effect unit is switched off. This is very usefull to compare your mix
with and without effects.
25. FOOT SWITCH connector
Here you can connect a foot switch to switch the internal effects on/off.
