Signals passing through the AUX RETURN level controls will proceed directly to MAIN MIX , with one exception (see next paragraph). 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 effects 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 almost 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 connection 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 normally, 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 technician 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).

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

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.

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
).
