UNPACKING THE LAMBDA STUDIO
Thoroughly inspect the Lambda Studio and packing materials for signs of damage.
Report any shipping damage to the carrier that delivered the product or dealer from
whom you purchased the product at once.
COMPUTER MINIMUM REQUIREMENTS
The Lexicon Lambda doesn't require an extremely powerful computer to use. However,
once you start playing multiple tracks, applying processing to these tracks with plug-
ins, and utilizing the other processing features available in your recording software,
more computing resources are required.
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 meet these
requirements. As with all such systems, adding more RAM than the minimum will
allow you to do more processing and improve performance, and more disk space will
give you more storage for your audio files.

LINE 1-2 GAIN
These knobs adjust the input gain levels of the Line 1 and Line 2 inputs.
PEAK LEDS
These LEDs light when the input signal is within 5 dB of analog clipping. If the Peak
LEDs flicker occasionally, the signal is approaching clipping levels, but this does not
necessarily indicate distortion or actual clipping.
MONITOR ASSIGN
These buttons select whether a pair of analog audio sources will be heard in stereo
or mono in the Direct Monitor Mix. In Stereo mode, the left inputs (Mic 1, Line 1)
are routed to the left monitor and right (Mic 2, Line 2) inputs are routed to the right
monitor.
In Mono mode, you’ll hear the selected inputs in the center of the Direct Monitor Mix
through the Headphone or Line outputs.
When a Monitor switch is in Mono, it does not change the signals going to the
computer in any way — they will still be separate and stereo in the computer.
For the cleanest
recording,
adjust the Gain
so the level
reaches at least
-6 on the Input
Bargraph Meter,
but never lights
the Clip LED

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 recording 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
occasionally.
USB LED
When the blue USB LED is on, it shows the Lambda Studio is powered and
communicating 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.
¼" INSTRUMENT INPUT JACK
This ¼" jack accepts unbalanced, low-level, high-impedance instrument sources such
as electric guitar, acoustic guitar with a pickup, or 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.

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
converter. 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 insert
cable (single TRS plug to two TS plugs). The tip is send and the ring is return.
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 44 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.
The Rear Panel

+48V PHANTOM POWER SWITCH
This switch 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.
USB PORT
The USB Port is used to connect the Lambda Studio to your computer and provides the
Lambda Studio hardware with power. A standard USB cable is included. The Lambda
Studio supports USB 2.0 full speed.

IMPORTANT:
To avoid damage,
do not plug a line
output into the Mic
In jacks unless the
+48V switch is
turned off.

CONNECTING TO THE LAMBDA STUDIO
The Lambda Studio is both a 4 x 2 x 2 mixer and a USB audio/MIDI interface that can
be used in a variety of audio applications. This section describes how to make basic
connections for the following functionality:
• Monitoring Audio
• Recording Audio
• Connecting a Recorder for Mixdown
MONITORING CONNECTIONS
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 balance
between the direct audio and playback audio from your computer (For a complete
description of the Monitor Mix control, see "Monitor Mix Control" on page 4).
You can monitor the audio through the 1⁄8" Headphone jack on the front panel,
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.
The Lambda Studio’s L/R Line Outputs have a nominal output of +4 dBu, and support
both balanced (¼" TRS) or unbalanced (¼" 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 (balanced TRS cables are recommended), 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 speakers.
2. Adjust the Lambda Studio's output volume with the Output Level knob. If using
both headphones and monitor speakers, adjust the level of the external power
amp or speakers using their gain controls after you’ve set the desired level in your
headphones.
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.
Connecting to the Lambda Studio – Monitoring Connections

8
RECORDING CONNECTIONS
Analog audio signals are created by microphones, synthesizers, mixers, and
instruments 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.
CONNECTING A MICROPHONE
Plug an XLR cable directly from a microphone into the desired Mic input on the
Lambda Studio rear panel.
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 an insert cable (¼" TRS to 2 x ¼" TS). 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 A LINE-LEVEL SOURCE
Plug a ¼" TS (unbalanced) or TRS (balanced) cable directly from the line-level
source into the desired Line In jack on the rear panel of the Lambda Studio. Line-level
sources include keyboards, drum machines, CD and cassette players, and external
microphone preamps and effects. If the line-level source has something other than ¼"
outputs, cable adapters can be used.
NOTE: When using the Line In 1 input, DO NOT plug a cable into the
Instrument input. Inserting a cable into the Instrument input disconnects the
Line In 1 input internally.
CONNECTING AN INSTRUMENT
Plug a standard ¼" TS (instrument) cable directly from the instrument into the
Instrument input jack on the front panel of Lambda Studio. Note that this will disable
the Line In 1 jack on the back panel.
IMPORTANT:
To avoid damage,
do not plug a line
output into the Mic
1-2 jacks unless the
+48V (phantom)
switch is turned OFF.
For the cleanest
recording, adjust
the Gain so the level
reaches at least
-6 on the input
bargraph meter,
but never lights the
“Clip” LED on the
loudest sound you’ll
be recording. If you
see the Peak LED
light constantly, turn
the Gain knob down
until it flashes only

MIXDOWN CONNECTIONS
After you record and mix your sessions in either Cubase®LE or other recording
software, you may want to mix them down to a DAT, tape recorder, CD recorder, or
other stereo 2-track recording device.
Mixdown Deck
Headphones
CONNECTING TO AN EXTERNAL RECORDER
Connect the Line Out L-R jacks on the back of the Lambda Studio to the left and
right recorder inputs respectively. 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 tape machine), start with
the Output Level knob on the Lambda Studio at about the 12 o’clock 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 read consistently between 0
dB to +4 dB, 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 0 dBFS (Full Scale)
mark without causing clipping (going over the 0 dBFS mark). As a general rule of
thumb, the loudest peaks in the audio material should peak at around -6 dBFS on the
recorder's input meter(s).
To hear the mix through studio monitor speakers, connect the outputs of the
2-track recording deck to the inputs of the amplifier or powered speakers. Adjust the
monitoring level using the output level of the recording deck or the input level of the
amplifier or powered speakers.
MIXING WITHIN CUBASE®LE
You can mixdown directly within Cubase LE or other recording software, and burn
an audio CD from that mix (provided your computer has a CD-R drive). Consult
the Cubase LE manual or documentation for your recording software for a complete
description of mixing within the software.
