Channel Faders

This adjusts the levels of both the post-EQ channel

signal headed directly for the

LEFT and RIGHT MAIN

master bus (via the

PAN/BAL pot), and the EFX send

signal headed for the master

EFX bus. The channel fader

does not control the

MONitor send level.

Clip LED

The channel

CLIP LED watches all the active electronic

stages in the channel circuit. Whenever any stage’s

signal peak approaches clipping to within

6 dB, the

CLIP LED circuitry captures and displays this event. See

under

GAIN control for more about this feature.

Monitor Master & Clip LED

This control regulates the overall level of the master

MONitor bus. The CLIP LED, like the others, fires at 6 dB

below the onset of actual clipping so that a small amount

of activity is quite acceptable. If the

LED flashes frequent-

ly, reduce the

MON MASTER setting, or possibly one or

more of the channel

MON send settings. The output of

the

MON MASTER bus goes to the MON OUT jack. It

also goes to

the EQ/AMP ASSIGN button where it can

be directed to the

EQ2 equalizer and then to the RIGHT-

channel of the built-in stereo power amplifier. Regardless

of the

EQ/AMP ASSIGN button’s operation, the MONitor

signal remains available at the

MON OUT jack so that it

can be used to drive an additional amp/speaker system.

Mon Out Jack

Located in the upper right area beside the

PHONES

jack,

MON OUT is the output of the monitor bus. It

is at line level (do not connect speakers to it directly)

and unbalanced. Connect your monitor power amp

or powered monitors here.

User tip: If another monitor system is in use, perhaps

full-range enclosures running off the main PA mix

as side-fills, you could connect a tape deck here

to record live performances. Plug a single

1/4-inch

male-to-dual 1/4-inch female Y adapter into the

MON OUT jack. Now simply run two of the appro-

priate patch cables

(probably 1/4-inch male-to-RCA

male) into the tape deck’s L & R line level inputs.

You will now have the advantage of being able to

mix for recording, independent of the PA mix.

Left & Right Main Masters

EQ/Amp Assign Button

The

MAIN master faders receive signals from the chan-

nel

PAN/BAL controls and determine the output signal

levels at the

L & R PRE-EQ LINE OUTPUT jacks.

User tip: Regardless of the ASSIGN button’s func-

tion, the

PRE-EQ LINE OUTPUT jacks will always

carry the unequalized

L & R stereo mix. This can be

useful if you are recording the live performance.

The

MAIN faders also determine the signal levels

destined for

the EQ/AMP ASSIGN button where they

are directed as follows:
