16. -20 dB SWITCH – When this button is engaged, the audio of that channel will be attenuated by 20 dB.
This can help increase the headroom and reduce distortion due to an overly loud input signal that
peaks frequently.
17. 2TK IN – You can use a standard stereo RCA cable to connect an additional audio source to this input.
The signal's volume can be adjusted with the 2TK IN LEVEL knob and sent to the monitor mix (CTRL
ROOM and PHONES) or main mix (MAIN OUT).
18. 2TK OUT – You can use a standard stereo RCA cable to connect this output to an external recording
device. The signal sent out these RCA outputs is the same as the MAIN OUT signal.
19. AUX OUT – You can use a 1/4" TRS cable to connect this output to the input of an external amplifier or
active monitor to create a custom monitor mix for onstage musicians. You can adjust this level with the
AUX SEND 2 knob. To use an external effects rack unit, compressor, etc. with the mixer, you can use
Y-cables to connect this output to the input of your external device, then connect the outputs of the
device to the STEREO RTN input.
20. STEREO RTN – You can connect the output of an external device to this input with a 1/4" stereo/TRS
cable. This is usually used for outboard effects devices but can also be used like an extra input channel
for synthesizers, drum machines, etc. Adjust this input's volume with the AUX/DSP RET knob. (If you
have an external device connected to the STEREO RTN jack, the internal effects processor will be
bypassed.)
21. AUX/DSP RET – Adjusts the volume of either the mixer's internal effects processor or signal being sent
into the STEREO RTN. When cables are inserted into the STEREO RTN, the internal effects processor
will be bypassed.
22. FX MUTE – Press this button to mute/unmute the effects.
23. FX CLIP/MUTE LED – The LED will flash if the mixer's internal effects processor signal is clipping. If
this happens, decrease the setting of the AUX SEND 2 knob or CHANNEL LEVEL knob.
24. EFFECTS SELECTOR – Selects the effect that the mixer's internal effects processor will apply to the
various channels. Each channel can send different levels of audio to the processor by adjusting its
AUX SEND 2 knob. See the EFFECTS section for an explanation of the available effects. (If you have
an external device connected to the STEREO RTN jack, the internal effects processor will be
bypassed.)
25. VARIATIONS SELECTOR – Selects the amount of the effect applied to the various channels.
26. FOOTSWITCH – When a latching-style footswitch is connected to this jack with a 1/4" TRS cable, it
can be pressed to allow all channels to bypass the mixer's internal effects processor.
27. 2TK IN LEVEL – Adjusts the level of audio sent into to 2TK IN jacks and routed to the main mix or
monitor mix.
28. 2TK TO – Set this switch to route the audio sent into the 2TK IN jacks to Channels 7/8 or to the main
mix.
29. GRAPHIC EQUALIZER – You can use these controls to adjust the equalization of the main mix
(MASTER) or monitor mix (MONITOR).
30. PHONES – Connect your 1/4" stereo headphones to this output. The MONITOR LEVEL knob controls
the volume.
31. MONITOR OUT – Use a standard 1/4" TRS cable to connect this output to your monitor or amplifier
system. The level of this output is controlled by the MONITOR LEVEL knob.
32. MAIN OUT – Use standard 1/4" cables to connect these outputs to the speakers. The level of these
outputs is controlled by the MASTER LEVEL knob.
33. MONITOR LEVEL – Adjusts the volume of the monitor mix (MONITOR OUT and PHONES).
34. MASTER LEVEL – Adjusts the volume of the main mix (MAIN OUT).
35. LED METERS – Shows the audio level of the main mix and monitor mix. Turn the volume down if the
+10 LED lights up excessively.
36. PHANTOM POWER – Activates/deactivates phantom power.
supplies +48V to the XLR mic inputs. Please note that most dynamic microphones do not require
phantom power, while most condenser microphones do. Consult your microphone's documentation to
find out whether it needs phantom power.
37. POWER LED – Illuminates when the mixer is on.
When activated, phantom power
