L MIX R (Master) Faders

The

L MIX R

(master) faders set the final level of the mix L

and R outputs. Assuming input

SENS

settings have been cor-

rectly set, the

L MIX R

(master) faders should be set close to

the ‘0’ mark to provide maximum travel on the faders for
smoothest control.

RET1~RET4 (Stereo Returns)

Four balanced stereo returns,

RET1

through

RET4

, are avail-

able for use as outputs of effects units or other stereo sources
and are mixed directly to the AUX or MIX/SUB busses at a
level set by the respective controls. The left-hand control sets
the return level to a choice of

AUX1

AUX2

(

AUX3

Lexicon

in the case of

RET4

), depending on the position of

the adjacent switch. The right-hand control sends the return
level to

MIX

SUB

, depending on the position of the adja-

cent switch (i.e., it is effectively a rotary fader).

If a mono source is used, plugging it into the left jack only
will automatically feed the signal to both left and right busses.

DIGITAL EFFECTS PROCESSOR

The built-in Lexicon Digital Effects Processor provides a wide
range of echo, reverb, and acoustic treatments to add fullness
to sound, complement room acoustics, or for specific effects.

LEXICON RET (Return)

LEXICON RET

is similar in operation to the stereo returns,

RET1

through

RET4

, but instead of taking an external

source, this section is fed from the output of the internal
Lexicon Digital Effects Processor. The left-hand control
sets the return level to a choice of

AUX1

AUX2

, depend-

ing on the position of the adjacent switch. The right-hand
control sends the return level to

MIX

SUB

, depending

on the position of the adjacent switch (i.e., it is effectively a
rotary fader).

PROGRAM SELECT

is a rotary switch that provides selection

of any one of 16 factory-programmed effect combinations,
as listed on the panel legend below the controls. These fac-
tory presets have been carefully implemented for this mixer
and should be suitable for most applications.

PARAMETER ADJUST

PARAM1/PARAM2

Two pre-programmed effects may be adjusted and saved in
on-board RAM (random access memory) using the

PRO-

GRAM ADJUST

encoder knob and

PARAM1/PARAM2

stor-

age switches. The best settings for a particular application
are found by experimentation and through careful listen-
ing to the final sound.

Adjustments are made by turning

PROGRAM ADJUST

while pressing down on

PARAM1

PARAM2

, and listen-

ing to the result. As soon as you release

PARAM1

PARAM2

, the setting will be held in internal RAM. Any

alterations to the pre-programmed settings are retained,
even if the mixer is turned off, and will be recalled the next
time the particular program is selected. If a setting differs
from the original default values, the

USER

LED will illumi-

nate.

NOTE: To restore a parameter to its factory setting, press down on

both

PARAM1

and

PARAM2

until the

USER

LED goes out.

LEXICON MUTE FOOTSWITCH

Lexicon effects may be remotely turned ON or OFF
through the

LEXICON MUTE FOOTSWITCH

jack (on the

rear panel). Use a standard latching (or non-latching) gui-
tar footswitch, or similar unit that provides an isolated
switch closure, and connect it as shown below. The effect
will be muted when the switch is closed.
