GAIN and VOLUME controls.
1 – PEAK LED
The L1200 and L2000’s MIC/LINE pre-amp also
includes a PEAK LED which, when illuminated,
indicates that the input signal is near overload.
2 - GAIN Control Knob
Each of the L1200 and L2000 channel’s pre-amp
stage has a variable GAIN control to help set a clean
level. The Mic/Line inputs’GAIN control has a range
of -6 to -50dB on the MIC input and +14 to -30dB on
the LINE input. The Stereo inputs’GAIN control has a
range of -10 to -50dB on the MIC input and +20 to
-20dB on the LINE input.

The L Series include several auxiliary signal paths,
or buses, that can be used to create independent
mixes for sending to the internal or external effects
processors, or to an external monitor system.
These buses start by sending the signal from each
individual channel, which is set with one of the
auxiliary control knobs. Then, the mix of all the
channels auxiliary level is ultimately sent to either
an internal effects processor, or to an output jack to
connect to an external effect or monitor system. To
help you control your effects and monitor mixes, the
L series has four auxiliary buses, with switching to
give you a possibility of 2 monitor mixes with two
effects sends, or 3 monitor mixes and one effects
send.

PRE….? POST….? What’s That?
In order to operate your mixer correctly, it is
important to understand the concept of PRE and
POST fader sends. An auxiliary bus that is set up
as PRE Fader routes, or sends, the signal to its
output from a point in the channels’circuit that is
electronically before the channel Fader. That means
the channel Fader has no effect on the PRE aux
level. A Pre Fader send is what you want to use for
a monitor mix, so when the level is changed for the
mix in the main PA speakers using the channel Fader,
the level in the monitor set by the aux control

INPUT CHANNEL SECTION - continued
7 – EFX- Post Fader Send
knob remains the same. An auxiliary bus that is set
up as POST Fader routes, or sends, the signal to its
output from a point in the channels’circuit that is
electronically after the channel Fader. That means
that the channel Fader also affects the level of a
POST aux send. A POST Auxiliary bus is what you
want to use (almost always) for sending to an effects
processor, either internal or external. When using
the POST aux sends, (while turning the channel
Fader up or down) the level of effects will track the
channel level correctly.
The L series provide high quality, 24 Bit digital
effects, and the level of effects can be set
independently on each channel. The channel’s
EFX knob controls the amount of signal that is
sent to the EFX bus feeding the internal DSP effect
processors.
8 - Channel Equalizer - Mono Channels
The L1200 and L2000 mic/line input channels
incorporate a 3-band, swept-mid equalizer
allowing you to adjust the high, mid-range, and
low frequencies independently on each channel.
The frequency centers, range of boost or cut, and
equalizer type for each band are described in the
following section:
4 – AUX 1-2 Pre Fader Send
Each of the L series’input channels include a pair
of Pre Fader Auxiliary sends; AUX 1-2 and their
control knobs adjust the amount of that channel’s
signal that is sent to the AUX 1-2 Output. The signal
feeding AUX 1-2 is sent before, or pre, the channel
Fader, so the channel Fader has no effect on the
AUX 1-2 output levels. The AUX 1-2 buses are usually
used to create a separate mix for a floor monitor
system.
HF (HIGH FREQUENCY) 12kHz +/- 15dB Shelving
type
The channel’s HIGH frequency response is flat when
the knob is in the “12:00”position. Rotating the
knob towards the right will boost the channel's high
frequency response at 12 kHz by 15dB, and rotating
it towards the left will cut the high frequency by
15dB.
5 – AUX 3 Pre/Post Fader
Each of the L series’input channels include an
Auxiliary send (AUX3) which can switch from Pre to
Post sends; AUX 3 and their control knobs adjust the
amount of that channel’s signal that is sent to the
AUX 3 Output. Aux 3 can be configured for pre or
post fader send using the PRE/POST switch (6). The
AUX 3 bus is usually used to create a separate mix for
a floor monitor system, but you can set the Pre/Post
switch to Post to use the send as en effects bus to an
external processor.
MF (MID FREQUENCY) CUT & BOOST
The MF knob is used in conjunction with the
FREQ knob to create the tonal shape in the mid-
range frequency when using the mono channel’s
equalizers. You can adjust the frequency on the
mid-range control with the FREQ knob, and use the
MF control to either boost or cut that frequency by
plus or minus 15dB. The channel’s MID frequency
response is flat when the MF knob is in the “12:00”
position.
6- PRE/POST switch
FREQ (MID FREQUENCY) Variable 100Hz – 8K
The FREQ is a control enabling you enhanced
capabilities in the tonal shaping of the input channel
signal. Thanks to the FREQ control, you have a
variable mid-range equalizer, allowing you to pin
point the exact frequency you want to boost or cut.
The MID SWEEP has a “fixed Q”of two octaves (the
amount, or width, of frequencies
The PRE/POST switch is used to select the point that
the AUX 3 bus uses to send the signal. When the
PRE/POST switch is set to PRE, the signal feeding
AUX 3 is sent before the fader, so the channel Fader
has no effect on that level. This is the normal setting
when using AUX 3 as a monitor send. When the PRE/
POST switch is set to POST, the signal feeding AUX
3 is sent after the fader, so the channel Fader has an
effect on that level, meaning the Aux level tracks up
and down with the channel Fader. This is the normal
setting for using AUX 3 as an effects send, since in
most applications when you set the channel louder
you want the effect to get louder too. When you
move the Channel Fader up or down the level of
effects will track the channel level correctly.

11 - SOLO/PFL (Pre Fader Listen) switch
The Mono Input channel’s PFL, or Pre Fader Listen
switch allows you to listen, or “solo”a channel or
group of channels in the headphones. When the
SOLO/PFL switch is pressed down, either mono PFL
or stereo SOLO is sent to the headphones. To listen
to the PFL, press the Meter Select switch, located
below the VU meter, down to select PFL. To hear the
stereo SOLO, the meter switch must be in the up

CUT & BOOST control) and can be set in a range from
100Hz to 8Khz.
LF (LOW FREQUENCY) 80Hz +/- 15dB shelving
type
The channel’s LOW frequency response is flat when
the knob is in the “12:00”position. Rotating the
knob towards the right will boost the channel's low
frequency response at 80 Hertz by 15dB, and rotating
it towards the left will cut the frequency by 15dB.
12 - 1-2 Group Assign switch
The 1-2 Group assign switch is used to assign the
input channel to the 1-2 Group output bus.
8 - Channel Equalizer - Stereo Channels
The L1200 and L2000 Stereo input channels feature
a 4-band equalizer allowing you to adjust the high,
mid, and low frequencies independently on each
channel. The stereo channel equalizer is laid out like
a mono input on the control panel input strip, but
internally, the equalizer is affecting a stereo signal
path. The channel’s frequency response is flat when
the knobs are in the “12:00”position. Rotating the
knob towards the right will boost the corresponding
frequency band by 15dB, and rotating it towards the
left will cut the frequency by 15dB. The frequency
centers, range of boost or cut, and equalizer type for
each band are as follows:
Note: The Group output follows the channel’s PAN
control, so if a channel is panned all the way to the
left it will only feed Group Output 1. Conversely, if a
channel is panned all the way to the right, it will only
feed Group Output 2.
13 – 3-4 Group Assign switch
The 3-4 Group assign switch is used to assign the
input channel to the 3-4 Group output bus.
Note: The Group output follows the channel’s PAN
control so if a channel is panned all the way to the
left, it will only feed Group Output 3. Conversely, if a
channel is panned all the way to the right, it will only
feed Group Output 4.
High: 12kHz +/- 15dB shelving type
High Mid: 3kHz +/- 15dB peaking type
Lo Mid: 500 kHz +/- 15dB peaking type
Low: 80Hz +/- 15dB shelving type
14 –MAIN Assign switch
The MAIN assign switch is used to assign the input
channel to the left and right stereo bus outputs.
15- VOLUME - Fader Level Control
The VOLUME Fader control adjusts the level of each
mono input channel.
9 - PAN Control
The L1200 and L2000’s PAN control is used to place
or position the mono signal into the stereo main Left
and Right MIX bus. You can create a stereo image by
panning some input signals to the left and others
to the right. The L1200 and L2000’s PAN control is a
Power-Pan circuit, which includes a 3dB dip in the
center position. This is desirable since there’s a 3dB
increase in gain when the mono input signal is heard
in both the Left and Right MIX bus.
10 - MUTE switch
The Mono Input channels feature a large, backlit
MUTE switch allowing you to easily turn that channel
on or off. When MUTE switch is illuminated, the
channel is off. Conversely, when the backlight is off,
the channel is on.

Controls and Functions
31 - MAIN 2 – control knob
USB I/O Section
The L Series mixers provide a second set of output
connectors carrying a duplicate of the MAIN MIX
signal for the purpose of feeding another speaker
zone or recorder. The MAIN 2 control knob is used to
set the volume of the MAIN 2 output.
The L series consoles incorporate a sophisticated
USB I/O with on board AD and DA converters
providing a digital audio path for connecting to a
PC running most any recording and/or playback
software. The INPUT and ASSIGN switch give you
added flexibility in routing the digital audio signal to
and from the PC.

The USB INPUT switch allows you to select one of
two stereo (or two channel) signal paths to feed the
USB output to send to the connected PC. When the
INPUT switch is in the up position, the USB signal will
feed from the MAIN left right mix. When the INPUT
switch is in the down position, the USB signal will
feed from the AUX 1 and AUX 2 buses which enables
you to create a unique mix to send to the PC.
35 – RETURN – USB return switch
The USB RETURN switch allows you to select one of
two stereo return paths to receive USB audio from
the connected PC. When the ASSIGN switch is in the
up position, the USB signal will return to the MAIN
mix bus. When the ASSIGN switch is in the down
position, the USB signal will return to the last pair
of stereo channels which enables you to playback a
recorded track in the MAIN mix, and you can use the
channels AUX sends to feed any of the AUX buses.
This will let you hear the USB playback tracks in the
monitor mixes.
The L Series 9-band stereo Graphic Equalizer allows you
to contour the frequency response of the MAIN mix bus
signal, providing a maximum of 12dB of cut/boost for
each frequency band. This is an especially useful tool for
cutting frequencies that cause annoying feedback. The
frequency response is flat when the sliders are in the cen-
ter position. Moving a slider in the positive direction will
boost that frequency by as much as 12dB, and moving
the slider in the negative direction will cut that frequency
by up to 12dB.

45– GROUP SOLO - switch
The left and right CLIP LED’s illuminate when the
signal from the selected bus is beginning to reach
a level where distortion occurs. If the CLIP lights
stay on, your mix is too hot and you need to lower
the level control. It is okay for the PEAK light to
occasionally light, however they should go off
quickly and not stay on.
The GROUP output’s 1-4 SOLO switch, also known
as AFL or After Fader Listen, allows you to listen to,
or “solo”, a GROUP send in the headphones. When
any of the GROUP 1-4 SOLO switches are pressed
down, that GROUP’s signal is assigned to the solo
bus and can be heard in headphones plugged in to
the PHONES connector located in the top panel jack
field. This allows you to listen to a GROUP send by
itself, let’s say, to check that a signal is not distorted
before it gets to the connected power amplifier.
Since the SOLO is AFL, the fader will affect the level
you hear in the Solo bus.
41- LED VU METER
The OUTPUT LEVEL METER allows you to monitor
the level of the signal, which is being sent to the
MAIN OUT jacks when the MAIN MIX Solo button
is pressed down. Depending on the position of the

the channel GROUP assign switches. In many appli-
cations when assigning a channel to a group, you do
not want it assigned to the MAIN mix, so be sure the
MAIN assign switch is up.

Mono Group Sends - Odd Even Panning
To create one or more mono subgroup mixes, it is
important to pay attention to the PAN knob. By using
the channel PAN knobs, you can create four mono
sub mixes.
49 - SOLO (AFL MAIN MIX) – switch
The MAIN MIX output’s AFL, or After Fader Listen
switch allows you to listen to, or “solo”, the MAIN MIX
in the headphones. When the MAIN MIX Solo switch
is pressed down, the left/right mix will be heard in
headphones plugged in to the PHONES connector
located in the top panel jack field. This allows you
to listen to the stereo mix , (let’s say), to check that
a signal is not distorted before it gets to the power
amplifier. Since the signal is sent after the MAIN MIX
level fader, you hear the signal with the added gain
from the MAIN MIX Level control. This switch also
allows you to view the Main Mix levels on the VU
meters.
If you want to send a group of channels to Group 1,
press the Group 1-2 assign switch down and set the
PAN knob all the way to left on those channels.
If you want to send a group of channels to Group 2,
press the Group 1-2 assign switch down and set the
PAN knob all the way to right on those channels.
If you want to send a group of channels to Group 3,
press the Group 3-4 assign switch down and set the
PAN knob all the way to left on those channels.
50 - MAIN MIX (left and right) - Level fader
The MAIN MIX Level fader adjusts the level of MAIN
left and right stereo mix.
If you want to send a group of channels to Group 4,
press the Group 3-4 assign switch down and set the
PAN knob all the way to right on those channels.
Stereo Group Sends
You can build a stereo sub group mix using two
group outputs.To do this using Groups 1 and 2, en-
gage the TO MAIN LEFT switch on GROUP 1 for the
left channel and engage the TO MAIN RIGHT switch
on GROUP 2 for the right channel. Since the GROUP
outputs follow the channel PAN knob, the stereo mix
will present at the GROUP 1 and 2 outputs.

At this point you can begin using your L Series console
with most any audio recording software, but you need
to select it as an input and output device within the
DAW. When selecting the inputs and outputs just look
for and select the USB Audio Codec.
For playback, you can return the USB stereo signal
directly into the Main left and right mix bus so that
the playback from the PC sums with the MAIN mix
on the console.

A - SEND - switch
The USB SEND switch is used to select the mix out-
put that is sent to the internal AD (analog to digital)
converter and then out the USB socket and then on
to a PC.The switch allows you to select either the
MAIN Left and Right or AUX 1 / 2 outputs.
You can also use the USB RETURN switch TO route
the signal from the USB output to the last stereo
channel.
To hear the USB playback in the MAIN mix, be
sure that the USB SEND switch is set to MAIN (up
position).
For recording a live performance, you can send the
MAIN Left and Right mix signal to the USB out for
recording exactly the same mix as you hear in the
sound system.
For added flexibility, you can assign the USB stereo
playback signal to the last stereo channels (11/12
on the L1200 and 19/20 on the L2000). This gives
you the ability to mix the signal in the MAIN mix,
and also, you can assign to the Auxiliary sends and
Bus outputs so you can mix the playback in floor
monitors or isolate the playback to a mix zone. Press
the USB RETURN switch down to return the USB
input to the last stereo input.
Be sure that the USB SEND switch is set to MAIN (up
position) to send the MAIN Left and Right mix to the
USB input.
The USB I/O is always active and it will send a stereo
signal based on the position on the USB SEND
switch. When the USB SEND switch is set to MAIN,
the signal sent to the computer will be comprised
of the input channels that are assigned to the MAIN
Left and Right Bus. The mix level follows the channel
FADER and the stereo image set by the channel’s
PAN control. You can also assign the USB out to feed
from the AUX1 and AUX2 outputs enabling you to
build a stereo mix for recording that’s independent
from the house sound system. Press the USB SEND
