15. MAIN MIX LEVEL LED Display- This LED display will show you the Main mix output level. Make sure that the
+10 LED only lights up occasionally. The optimal level is between -10 and 0 on the LED. If only the -30 LED
lights up or does not come on your S/N ratio will be degraded.
16. MONITOR LEVEL – This adjusts the volume of the Monitor output.
17. MASTER LEVEL-
18. PHANTOM POWER – This switch activates and deactivates phantom power. When activated, phantom power
supplies +48V to the XLR mic inputs and the LED above the switch will be lit. 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.
MASTER I/O (INPUT/OUTPUT)
19. AMPLIFIER Mode Switch-
This switch provides three
modes: MAIN/MAIN,
MAIN/MONITOR and
BRIDGE. Select any one of
these modes to route the
signals to the
corresponding jacks
according to the speaker
panel connection. This
switch only affects the rear panel outputs. The front panels outputs are unaffected by this switch.
• MAIN/MAIN- When the switch is set to this, the amp will send the main mix to the rear panel Speakon*
jacks or the rear panel ¼" jacks.
• MAIN/MON- When the switch is set to this, the amp will send the main mix to the OUTPUT 1 Speakon
jack and 1/4'"jack. The monitor mix will be sent to the OUTPUT 2 Speakon jack.
• BRIDGE- When the switch is set to this, the amp will send the main mix to the rear panel OUTPUT 2
Speakon jack.
20. MAIN OUTPUTS – These 1/4" line level outputs can be connected to powered speakers or an amplifier
system. The level of these outputs is controlled by the Main Level knob.
21. MONITOR OUTPUT- This line level
powered speaker.
22. PHONES – Connect your 1/4" stereo headphones to this output.
23. 2-TRACK INPUTS – Connect these to the outputs of an external sound source using standard stereo RCA
cables (sold separately). You can send this to channels 9/10 (using the 2-TRACK to 9/10 switch) or to the
main outputs (using the 2-TRACK TO MAIN switch).
24. 2-TRACK OUTPUTS – You may connect these outputs to the inputs of an external recording device using a
standard stereo RCA cable (sold separately).
25. AUX OUT- This outputs the line level signal sent from a channel's AUX1 Pre knob to the Monitor Output. You
can use it to feed the inputs of another stereo multi-effects unit (using a Y-type cable sold separately).
26. STEREO RETURN- This stereo jack is used to route a stereo signal to the Main, Monitor and Phones outputs
by adjusting the FX TO MAIN and FX TO MON knobs.
27. 2-TRACK TO– If you position this switch to the left you will route the signal fed into the TAPE IN sockets into
CH9~10 path, and the signal will be affected by channel level control, channel EQ, DSP send, and MAIN level
control. Positioning this switch to the right will route the TAPE IN signal into Main mix bus. In this case signal
will be affected only by Main level control.
