FADER MASTER. A 60mm smooth travel fader is

fitted providing +10dB gain above the nominal 0dB

operating position. These faders control the output

level of group/aux 1-12. They are not part of the

console VCA group system.

TB ENABLE. Press these to enable talkback to

any combination of grp/aux master outputs. When

selected, pressing the TALK TO TB switch routes

the talkback mic signal, or pressing the OSC/NOISE

TO TB switch routes the oscillator/noise generator

signal to the output. When not selected, pressing

these switches does not affect the output. The

talkback and osc/noise signals are routed pre-

insert.

MUTE. This momentary action switch turns the

grp/aux master signal on or off. The master can

also be muted by the mute groups, VCA group

mutes, snapshot memories (externally controlled),

and MIDI note on/off messages. The switch

illuminates when the signal is muted.

The switch also functions as an edit key when in

EDIT GROUPS or EDIT SAFES mode. The mute

status is always displayed on the switch regardless

of mode.

SAFE / EDIT. This green LED has a different

function according to console mode:

Normal The LED lights when the master has been

made safe from the snapshot and MIDI automation.

Edit Safes Continues to indicate which masters

are automation safe while they are edited.

Edit Groups The LED lights to indicate that the

master is assigned to the MUTE group.

MIX SIGNAL METER. The 5 LED bar meter

displays the post-mute, pre-fade mix signal level.

SIG lights to display signal presence at –26dB, -6, 0

and +6 display normal signal level, and PK (peak)

lights when the signal is within 5dB of clipping. PK

senses the signal pre and post-fader to warn of

potential overload.

If the red PK LED lights check the channels feeding

the mix for correct operating level and reduce the

input level if necessary. You can use VCA groups

to simultaneously control the level of more than one

channel. Also check inserted processing for

correct operating level.

PFL/AFL Monitoring

The ML4000 intelligent P/AFL system provides the

following operating capabilities:

Mono or stereo AFL. Press a single AFL switch

to listen to that master as a mono signal fed to both

left and right channels of the headphones and local

monitor. Press two related AFL switches together

to listen to a related pair in stereo, ideal when

checking in-ear monitor mixes. The odd number

master is fed to the left channel, even to right.

Latching or momentary action. The switch

provides latching or momentary action depending

on how long it is held down. Press and hold for

longer than 1 second for momentary action.

AFL override monitor. Pressing any master AFL

automatically overrides the currently selected

monitor source. Releasing AFL restores that

selection.

PAFL override AFL. Pressing any channel PAFL

overrides the current AFL selection. Releasing

PAFL restores AFL.

AFL cancel PAFL. Pressing an AFL while one or

more PAFL is selected cancels that PAFL selection

and selects the AFL.

Auto cancel or Add mode. The master section

ADD MODE switch determines if pressing a

channel PAFL cancels or adds to any previous

selection.

Clear all. Pressing the master section CLEAR ALL

switch turns off any PAFL / AFL switches selected

and restores the monitor source.

AFL. Press this switch to listen to the master

signal in the headphones or engineers monitor

without affecting the main outputs. The signal is

monitored post-insert, post-fader, pre-mute so that

any adjustments made to the faders or inserted

processing such as EQ can be checked.

IDENT STRIP. Identifies the master numbers and

provides a write-on area. The use of low adhesion

artist or masking tape is recommended.
