MASTER SECTION

11. STEREO GRAPHIC EQ: There are two graphic EQs each with 9 adjustable bands; one is for the MAIN mix

and the other is for the MONITOR mix. With the faders you can boost or cut the selected frequency by +/-15 dB

at the indicated frequencies. When all faders are at the center position, the equalizer is disabled.

12. FEEDBACK TERMINATOR Button (MONITOR mix)- This button activates the feedback detection in the

monitor signal path. Feedback will be identified at a certain frequency when the corresponding fader LED lights

up. Feedback produces an unpleasant speaker "howling" or "whistling". In order to eliminate feedback, turn

down the corresponding fader until feedback

disappears.

13. MONITOR LEVEL LED Display- This LED display

will show you the monitor 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 doesn't come on, your

S/N ratio will be degraded.

14. FEEDBACK TERMINATOR Button (MAIN mix)-

This button activates the feedback detection function

in the Main mix signal path. Feedback will be

identified at a certain frequency when the

corresponding fader LED lights up. Feedback

produces an unpleasant speaker "howling" or

"whistling". In order to eliminate feedback, turn down

the corresponding fader until feedback disappears.

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 doesn't not come on your S/N ratio will

be degraded.

16. MONITOR LEVEL – This adjusts the volume of the Monitor output.

17. MASTER LEVEL- This adjusts the overall volume of the MAIN output and HEADPHONE out.

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

balanced output is used to connect the

input of an external amplifier or 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.
