Powerful software for audio recording requires a powerful computer with the right
operating system software, processor, memory, and hard drive space. Most computers
currently sold already meet these requirements, or can be upgraded to be compatible
with the Lexicon Lambda Desktop Recording Studio. As with all such systems, adding
more RAM than the minimum will allow you to do more processing and improve per-
formance, and more disk space will allow you to record more tracks for a longer time.
See the Lambda Studio Software Installation Guide and the Cubase LE manual for more

The Front Panel
MONITOR MIX CONTROL
The Lambda Studio™ gives you the ability to hear your analog input signals directly
and immediately while recording, without having to adjust levels in software, and
before the delay caused by digital converters and computer recording latency. This
zero-latency analog monitoring is controlled by the Monitor Mix knob, which you
can use to adjust the blend between the Lambda Studio’s live analog inputs (called
“Direct”) and any sounds coming back from the computer via USB (“Playback”).
To adjust the playback mix coming back from the computer (previous tracks, effect
returns etc.), use the faders on the Mixer screen of the software. To hear only the live
source input signals plugged into the Lambda Studio, turn the Monitor Mix knob
fully left to Direct. To hear only the mix from the computer, turn the Monitor Mix
knob fully right to Playback. The output from the Monitor Mix control is routed
directly to the Line and Headphone outputs. This ability to easily control the relative
levels of computer audio playback and latency-free live analog inputs is very useful
when overdubbing.
OUTPUT LEVEL
This knob controls the overall output level of the Lambda Studio’s Line and Headphone
outputs.
INPUT BARGRAPH METER
This LED Meter shows the signal level going into the A/D converters. When the Input
Bargraph Meter’s Clip LEDs illuminate, input signals are clipping the A/D converter.
Adjust the gain with the Mic and Line knobs so that the -6 dB LED flashes only occa-
sionally.
USB LED
When the blue USB LED is on, it shows the Lambda Studio is powered and communi-
cating with your computer via USB, and audio and MIDI signals can pass in and out
of the system.
+48V PHANTOM POWER LED
This LED indicates that 48 volt phantom power is active on the Mic 1 and Mic 2 inputs,
providing phantom power for condenser microphones that require it to operate. Turn
phantom power on or off as needed with the switch labeled +48V on the rear panel.
1⁄8" HEADPHONE OUTPUT JACK
The high powered Headphone output accommodates stereo headphones with an 1⁄8"
stereo plug.
" INSTRUMENT INPUT JACK
This ¼" jack accepts unbalanced, low-level, high impedance instrument sources such
as electric guitar, acoustic guitar with a pickup, and electric bass. The input gain is
adjusted using the Line 1 knob on the front panel. When an instrument is plugged into
this input, it disables the Line 1 audio input on the rear panel.

The Rear Panel
THE REAR PAN EL
The Lambda Studio™ rear panel offers the following features:
LINE IN 1-2
These ¼" inputs can accept both balanced (3-conductor TRS) and unbalanced (2-
conductor TS or instrument) audio sources. Each input gain is adjusted individually
using the Line 1-2 gain knobs on the front panel.
INSERT 1-2
Each mic input is equipped with a TRS insert point. Inserts provide a send and return
of the input channel’s signal directly after the mic preamp and before the A/D convert-
er. You can insert any line level signal processor (such as a compressor or equalizer)
to pre-process the mic signal before it is recorded, using a standard “stereo splitter”
(single TRS to two TS) cable. The tip is send and the ring is return.
IMPORTANT:
Do not plug a line
output into the Mic
In jacks unless the
+48 V (phantom)
switch is turned OFF
to avoid damage.
MIC 1-2 INPUTS
These balanced XLR inputs feature high-quality mic preamps designed specifically for
low-impedance professional microphones. The input gain is adjusted using the Mic
1-2 gain knobs on the front panel respectively, with 50 dB of gain at the maximum
setting.
LEFT/ RIGHT LINE OUTPUTS
These outputs support balanced TRS or unbalanced TS ¼" connections. These
outputs can be connected to a mixing board, power amplifier, powered studio monitors,
recorder, or another line level input.
MIDI IN AND OUT
The MIDI jacks provide MIDI input and MIDI output to and from your computer.
Connect your MIDI keyboards, sound modules, and external controllers here.

Connecting to the Lambda Studio
+48V PHANTOM POWER SWITCH
IMPORTANT:
This enables the phantom power to the Mic 1 and Mic 2 inputs. Dynamic
microphones do not require phantom power to operate, but are not harmed by
it. Most condenser microphones do require phantom power to operate. If you are
unsure about the phantom power requirements for your microphone, consult your
microphone’s documentation or contact the manufacturer. This switch should be
OFF if you are connecting any line-level source to the Mic In jacks.
Do not plug a line
output into the Mic
In jacks unless the
+48 V (phantom)
switch is turned OFF
to avoid damage.
USB PORT
The USB Port is used to connect the Lambda Studio™ to your computer and pro-
vides the Lambda Studio hardware with power. A standard USB cable is included. The
Lambda Studio supports USB 2.0 full speed.
CO N N ECTIN G TO THE LAMBDA

MO N ITO RIN G CO N N ECTIO N S
The Lambda Studio allows you to monitor audio both from the hardware inputs
(Direct) and from the computer (Playback). Use the Monitor Mix control to bal-
ance between the direct audio and playback audio from your computer (For a com-
plete description of the Monitor Mix control, see page 11).
You can listen to (or monitor) the audio through either the 1⁄8" Headphone jack
on the front panel, or through studio monitors using the ¼" L/R Line Out jacks on
the rear panel, or both. The output level of both the L/R Line Out jacks and the
Headphone jack are controlled with the Output Level knob above the Headphone jack
on the front panel.
Lambda Studio’s L/R Line Outputs have a nominal output of +4dBu, and support both
balanced ( " TRS) or unbalanced ( " TS) connections.
CONNECTING HEADPHONES:
1. Connect headphones to the Headphone jack located on the front panel of the
Lambda Studio. The Headphone jack accepts an 1⁄8" TRS connector.
2. Adjust headphone volume with the Output Level knob.
CONNECTING TO MONITOR SPEAKERS:
1. Using ¼" cables, connect the L/R Line Out jacks on the rear panel of the Lambda
Studio to the appropriate inputs on your mixer, power amp, or powered monitors.

CONNECTING TO A HOME STEREO
Connect the Line Out 1-2 jacks on the rear panel of the Lambda Studio™ to the
appropriate inputs on your stereo, typically the Tape In or Aux In jacks, using a ¼"
to male phono (RCA) connector or adapter. Keep the Output Level knob on the
Lambda Studio low at first, raising it slowly to match the level of other units connected
to the stereo.
ABO UT RECO RDIN G CO N N ECTIO N S
Analog audio signals are created by microphones, synthesizers, mixers, and instru-
ments with magnetic pickups.
Of these sources, microphones and magnetic instrument pickups have the lowest
output level, and generally require the most amplification. Keyboards, preamps, and
mixers output “line level” audio, which varies with each device between the -10 dBV
and +4 dBu standards.
TO CONNECT A MICROPHONE
Plug an XLR cable directly from a microphone into the desired Mic input on the
Lambda Studio rear panel.
IMPORTANT:
Do not plug a line
output into the Mic
1-2 jacks unless the
+48 V (phantom)
switch is turned OFF
to avoid damage.
TO ACTIVATE PHANTOM POWER
If your microphone requires phantom power, first make sure the microphone is
connected, then press the Phantom Power switch (labeled +48V). The +48V
Phantom Power LED on the front panel indicates the phantom power is active. If
your mics don’t need phantom power, it is best to leave it off.
USING THE ANALOG INSERTS
The analog inserts require a ¼" TRS to 2 x ¼" TS adapter cable. The
signal from the tip should be routed to the input of your outboard processor and
the output of your processor should be routed to the ring.

CONNECTING TO AN EXTERNAL RECORDER
Connect the Line Out L-R jacks on the back of the Lambda Studio™ to the left
and right inputs, respectively, on your recorder (cassette deck, CD burner, or other
recorder with analog inputs). You may need adapter cables if your mixdown deck
has RCA input jacks. Refer to your recorder's operator's manual for more information
about setting recording levels.
If you are connecting to an analog mixdown deck (such as a cassette recorder), start
with the Output Level knob on the Lambda Studio at about the 12 o’clock (straight
up) position, and the recorder’s input level also at or near 12 o’clock. Adjust the
Output Level knob on the Lambda Studio until the meters on your recording deck
(NOT the Lambda Studio) read consistently between 0dB to +4dB, raising the input
level control on the recorder if necessary.
If you are connecting to a digital recorder such as a DAT or CD recorder, set the input
level(s) on the recording device all the way open, to their maximum setting, and
then adjust the Output Level knob on the Lambda Studio until the meters on your
recording deck device consistently peak just below the 0dBFS (Full Scale) mark with-
out causing clipping (going over the 0dBFS mark).
To hear the mix through control room speakers, connect the outputs of the recorder to

Recording Using the Microphone/Line Input
To check the input level from the microphone or Line Input:
1. If you are using a mic and have connected the Lambda Studio™ to some moni-
tors, turn them down or off to avoid feedback.
2. If you want to hear the audio source in headphones, turn up the Lambda
Studio™ Output Level knob and turn the Monitor Mix knob counter-clock-
wise (towards the Direct side), then press the Monitor Assign button between
Mic 1 and Mic 2 or Line 1 and Line 2 so it is in the Mono position. This will
let you hear output on both sides of your headphones when recording only one
microphone or line level source.
3. Speak or sing into the microphone or play the line level source while gradually
increasing the gain by turning up the Mic 1 or Line 1 knob until you see the
Peak LED light next to the Mic 1 or Line 1 knob flash occasionally. Check the
Input Bargraph Meter on the front of the Lambda Studio to make sure you are
not clipping the A/D converters (although it's okay to light the -6 LED occasion-
ally).
To start recording:
1. Click the Record button on Cubase® LE’s Transport control.
2. Speak or play an instrument into the microphone or line input.
3. When you are finished recording press the Stop button.

Recording a Guitar Using the Instrument Input
of the original track in your monitor by adjusting the controls for channel 1 within
Cubase® LE’s Mixer window.
3. Click on Record and record the second (overdubbed) track.
B. RECORDING A GUITAR USING THE INSTRUMENT INPUT
This section explains how to record using the ¼" Instrument input jack on the front
panel.
1. Plug your electric, acoustic, or bass guitar into the Instrument input jack on the
front of the Lambda Studio™ hardware.
The Instrument input uses the same recording channel as the Line 1 input;
anything plugged into the ¼" Line 1 input jack on the back of the Lambda
Studio will not be recorded when a cable is connected to the ¼" Instrument
input jack on the front panel.
NOTE: This jack is intended for electric guitar and bass, or acoustic instrument
pickups, not line-level signals such as the output of keyboards or a direct out from
a guitar amplifier. For those, use the Line 1-2 input jacks on the back of the
Lambda Studio hardware.
2. Press the Monitor Assign button between Line 1 and Line 2 knobs so that it
is in the Mono position.
3. Open Cubase LE, go to File and select New Project>Default, and a project
location. (See Section I for more information.)

Recording MIDI with the Lambda Studio
SECTION II - RECORDING MIDI WITH THE LAMBDA STUDIO™
The Lambda Studio™ also functions as a MIDI interface. This allows you to record MIDI
data into a MIDI track of Cubase® LE, and play that MIDI data back from the computer
into a keyboard, sound module or effects processor.
Here is an example of recording a MIDI track in Cubase LE using a MIDI keyboard:
1. To record MIDI data into the computer, connect the MIDI out from the keyboard
to the MIDI In on the Lambda Studio. Connect the MIDI Out from the Lambda
Studio hardware to the MIDI in on the keyboard.
2. To hear your keyboard, you either need to run the line output of the keyboard to
one (mono) or two (stereo) Line inputs on the back of the Lambda Studio, or
use the keyboard's headphone output.
3. Open Cubase LE and start a new default project. Click on the gray area (not on
the buttons) of the MIDI Track 1 window (labeled MIDI 01).
4. In the Inspector, click the IN: box and select Lexicon® USB MIDI.
5. Click the OUT: box and select Lexicon USB MIDI for the MIDI
outputs. Click the Record Enable button
on MIDI track 1.
6. Click the Record button on the Transport and play your keyboard. You are now
recording MIDI data from the keyboard. If you don’t see data in the track, check
the settings of the keyboard to make sure it’s set to transmit on the same MIDI
channel that Cubase LE is set to receive on. In some cases, you may want to set the
keyboard to “local off” and set Cubase LE to “Echo” mode. For more information,
consult the Cubase LE online manual and your keyboard’s manual.

Using Software Input Monitoring
SECTION III - USING SOFTWARE INPUT MONITORING
The previous examples have turned off Cubase® LE’s Input Monitoring software switches
while recording tracks, and used the Monitor Mix knob on the front of the Lambda
Studio™ hardware to directly monitor an input without latency. Software monitoring
lets you listen to software-based effects in real time and adjust the monitor mix indepen-
dently of the recording levels, but also introduces some latency (delay) into the input
signal. The amount of latency depends on the amount of buffers assigned in the ASIO
control panel. See page 32 for more information about adjusting buffer settings.
1. When using Cubase LE’s input software monitoring with the Lambda Studio, you
will want to set the Monitor Mix knob all the way to the Playback side.
2. Click the Input Monitoring
button on the track you are recording to. You
will now be able to hear your input. Now you can try assigning an effect on the
input. This example assigns a Pantheon™ reverb.
3. Click the Track Edit button.

Adjusting the buffer Settings
SECTION IV - ADJUSTING THE BUFFER SETTINGS
Audio latency is the minimum time required for a computer to store recorded audio
from an audio interface into the recording application memory and playback that
same recorded audio back out audio interface output.
After the audio has been converted to the digital domain, it is passed to a buffer before
it is processed by the driver and then passed to the audio application. An audio buf-
fer is a reserved segment of memory used to hold this advance portion of audio data
to compensate for momentary delays in processing. The size of an audio buffer is
the maximum number of samples the buffer can hold. For sound coming from the
computer, there is an output buffer before the digital to analog conversion. "Buffering"
introduces latency, since a buffer needs to fill up by a certain amount before the data
can continue along the chain.
The buffers in Cubase® LE were automatically set at a safe setting for your computer
when you installed the software. If you are using Input Monitoring, you may wish to
adjust the amount of buffering to reduce this latency, or perceived delay in the input
vs. output of audio. Lowering the buffers will lower the amount of latency when using
Input Monitoring. Setting the buffers too low will result in unwanted digital artifacts,
such as popping or crackling and possibly audio dropout. The faster the computer
(Hard Disk and CPU), the lower you will be able to adjust the buffer setting without
negatively impacting the audio. For more information, consult the Cubase online
documentation.
A. ADJUSTING THE BUFFERS IN WINDOWS® XP
1. Open Cubase LE and go to Devices>Device Setup.
2. Click on VST Multitrack.
3. Click the Control Panel button. You will now see the ASIO control panel. The

4. When you are finished adjusting the buffer size, click the OK button and return to
your project to test the results.
