Signals passing through the

AUX RETURN

level

controls will proceed directly to MAIN

MIX , with one exception (see next para-
graph). The

AUX RETURNS do not have

MUTE/ALT 3-4 switches, so if you want
these signals to get to the

ALT 3-4 mix, you’ll

have to patch the effects device’s outputs
into one of the stereo channels, and

MUTE/

ALT that channel .

EFX TO MONITOR

The idea behind this great feature is simple:

If you want to add reverb or delay to the stage
monitor mixes, this is the switch for you. The
implementation leading up to the switch is the
tricky part:

With the switch up,

AUX RETURN 1 and 2

behave normally — they deliver their signals
into the

MAIN MIX. With the switch down,

AUX RETURN 1 still behaves normally, but
AUX RETURN 2’s level control will feed AUX
SEND 1 instead of the MAIN MIX.

Still with us? Good. So far, with the switch

down, we have

AUX RETURN 1 feeding the

MAIN MIX and AUX RETURN 2 feeding AUX
SEND 1. Now, suppose you only have one ef-
fects device, and you want it to feed both the
MAIN MIX and AUX SEND 1. That’s where
“jack normalling” comes in.

JACK NORMALLING

Jack normalling (not to be confused with

Jack Normalling, Chicago Cubs utility infielder,
1952-61, .267 LBA) is a feature found on al-
most every mixer, keyboard and effects device.
These jacks have special spring-loaded pins
that connect to the signal pins, but when
something is plugged into the jack, that con-
nection is broken.

These normalling pins can be used in all

sorts of ways. The ubiquitous phrase “

LEFT

(

MONO)” means that if you plug a signal into

the

LEFT side and have nothing in the RIGHT

side, that signal is also fed to the right input,
courtesy of jack normalling. As soon as you
plug something in the

RIGHT side, that

normalled connection is broken.

How does all this relate to the

EFX TO

MONITOR switch? AUX RETURN 1’s inputs
are normalled to

AUX RETURN 2. If you have

one effects device, plug it into

AUX RETURN 1.

Plug nothing into

AUX RETURN 2. Now the

signals feeding the

AUX RETURN 1 inputs will

also be sent to the

AUX RETURN 2 inputs.

Engage the

EFX TO MONITOR switch, and

now the

AUX RETURN 2 knob will become an

additional

AUX SEND 1 knob for the signal at

the

AUX RETURN 1 . Say that ten times!

Once again,

AUX RETURN 1 will behave nor-

mally, as always.

Congratulations! You’ve just read about all

the features of your 1402-VLZ

PRO. You’re

probably ready for a cold one. Go ahead. The
rest of the manual can wait.

MODIFICATIONS

For most folks, the 1402-VLZ PRO works just

fine the way it is. But for special applications,
there are three signal routing changes that can
be performed easily on the 1402-VLZ PRO. Easy
for someone with soldering experience, that is.
If you don’t know how to solder, find a techni-
cian that can. This is NOT a good place to learn!

• Modification A changes AUX SEND 2 to be

pre-fader, pre-mute instead of post-fader,
post-mute.

• Mod B changes AUX SEND 1 (in

post

mode) and AUX SEND 2 to receive signal
regardless of the channel’s MUTE/ALT
switch position, but still be

post-fader

(GAIN knob).

• Mod C changes the SOURCE matrix’s

MAIN MIX selection to tap the stereo
signal before the MAIN MIX level control
(

pre) instead of after (post).

Instructions for performing these modifications

can be found on our website at www.mackie.com
