5. Next, click in the Output tab and select USB Audio
Codec (figure 11). You may notice that the Volume
slider sets itself to the full level. This will allow you
to have full range using the L Series’ hardware MAIN
Volume control.
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.
Recording from the L Series’ USB I/O
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.
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.
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

switch down to send the AUX1 and AUX2 mix to
the USB input.

B - RETURN - switch
The USB RETURN switch is used to route the signal
presented to the internal DA (digital to analog)
converter, that’s been received from a USB digital
audio connection typically from a PC. The RETURN
switch allows you to select a return either directly
to the MAIN Left and Right mix or the last stereo
channel (channels 11/12 on the L1200 and 19/20 on
the L2000).
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.
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 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.
C - MONITOR – switch
The MONITOR switch is use to assign the USB return
to the headphones. Press the USB MONITOR switch
down if you want to hear the USB playback in the
headphones.
