CONTROL ELEMENTS

29- SUBGROUPS Fader

These faders are used to control the levels of the signal send to the SUB-
GROUPS OUT, the adjustable range goes from -

to +10 dB. Any channel

that is assigned to the subgroups, not muted and not turned down will be
assigned to the SUB OUTS.

30- 2TK LEVEL & TO MIX Button

By rotate the knobs, you can adjust the stereo signals level of 2TK input and
engaging the switch allows you to combine the 2-Track output with the Main
Mix. In other words, feeds the 2-Track In signals into Main L/R output.

31- Control Room Source

signals, and also be sent to the Control Room, Phones and Meters.

32- PHONES/CTRL ROOM Controls

Rotate these knobs to adjust the stereo level of CTRL ROOM and PHONES
outputs separately, which can be varied from -

to MAX.

You can choose to monitor any combination of MAIN MIX, SUB1-2, SUB 3-4
and 2TK IN via these Matrix switches. Engaging these switches, the stereo
signals will be delivered to the Phones, Control Room and Meters display.

NOTE: The SOLO function can never affect the mix at main recording output,

and also can't be affected by channel's MUTE switch.

33- SOLO MODE Button

This button provides two modes: up for PFL (Pre-Fader-Listen) mode, down
for AFL (After-Fader-Listen) mode. Engage the button, the soloed signal will
output after the Level control, otherwise, release the button will output the
soloed signal before the Level control.

34- POWER LED

The LED indicates when the power is ON.

35- PHANTOM LED

This LED indicates when the phantom power is switched on.

CONTROL ELEMENTS

These 1/4" phone jacks will be used to send the Control Room signal to the
studio monitor speakers or a second set of PA.

51- CTRL OUT Jacks

This 1/4" phone jack is balanced/unbalanced mono mix output connector, it
can be regarded as a sum output of the left and right of MAIN MIX.

50- MONO OUTPUT Jack

This knob sets the level of mono mix output signal, which can be varied from
-

to +15 dB.

49- MONO Level Control

These 1/4" phone jacks are used to send out the signal from the AUX Bus to
external devices such as effect units and/or stage monitors.

54- AUX SENDS Jacks

Use these stereo 1/4" phone jacks to return the stereo signal of an effect unit
to the Main Mix. Alternatively you can also use them as an extra auxiliary input
via using the AUX RETURN level control as volume control. The signal will be
sent directly to MAIN MIX control.

55 AUX RETURNS Jacks

56- DIRECT OUTS

These 1/4" phone jacks are used to connect the inputs of deck or secondary
in a complicated PA live sound system. You will find it is the best tool when
you operate the SUBGROUPS OUT.

53- SUBGROUPS OUT Jacks

Each Mono MIC/LINE Channel is equipped with the 1/4" phone jack for
directing output. These jacks are used to send the signal from the channel
path to external device for recording function etc..

52- SUBGROUPS INSERT

These 1/4" phone jacks are insert points. They are used to connect process-
ors, such as compressor, limiter, EQ etc.. When insert external processor
into these jacks, the subgroup stereo signal will be taken out, then returned
to before subgroups fader. Of course, these

jacks must be stereo (Tip

Send/Ring Return).
