The FRONT Panel

The Lambda Studio front panel offers the following features:
These knobs adjust the input gain levels of the Mic 1 and Mic 2 inputs.

Line 1-2 Gain

These knobs adjust the input gain levels of the Line 1 and Line 2 inputs.
These LEDs light when the input signal is within 5dB of analog clipping. If the Peak LEDs flicker occasionally, the signal is approaching clipping levels, but 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, youll 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 waythey will still be separate and stereo in the computer.

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 Studios 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.
This knob controls the overall output level of the Lambda Studios Line and Headphone outputs.

INput bargraph meter

This LED Meter shows the signal level going into the A/D converters. When the Input Bargraph Meters 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.
8" Headphone Output Jack
The high powered Headphone output accommodates stereo headphones with an 18" stereo plug.
" Instrument Input Jack
This " 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.

TO CONNECT A LINE LEVEL SOURCE
Plug a " TS (unbalanced) or TRS (balanced) cable directly from the line level source into the desired Line In jack on the rear panel of Lambda Studio. Line level sources include keyboards, drum machines, CD and cassette players, or external microphone preamps and effects. If the line level source has something other than " outputs, cable adapters can be used.

TO CONNECT AN INSTRUMENT

Plug a standard " 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.
After you record and mix your sessions in either Cubase LE 4 or other recording software, you may want to mix them down to a DAT, audio cassette, or other stereo 2-track recording device.
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 youll be recording. If you see the Peak LED light constantly, turn the Gain knob down until it flashes only occasionally, on the loudest part of the performance. DO NOT TURN DOWN A GAIN CONTROL TO GET THE RIGHT MIX IN YOUR HEADPHONES OR MONITORS WHILE RECORDING. USE THE MONITOR MIX CONTROL FOR THIS PURPOSE.

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 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 oclock (straight up) position, and the recorders input level also at or near 12 oclock. 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 without causing clipping (going over the 0dBFS mark). To hear the mix through control room speakers, connect the outputs of the recorder to the inputs of the control room amplifier or powered monitors. Adjust the control room

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 4, 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 4 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.

MIDI OUT goes to MIDI IN of the keyboard MIDI IN goes to MIDI OUT of 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 4 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 dont see data in the track, check the settings of the keyboard to make sure its set to transmit on the same MIDI channel that Cubase LE 4 is set to receive on. In some cases, you may want to set the keyboard to local off and set Cubase LE 4 to Echo mode. For more information, consult the Cubase LE 4 online manual and your keyboards manual.
Using Software Input Monitoring
Section III - Using software Input Monitoring
The previous examples have turned off Cubase LE 4s 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 independently 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 4s 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.
4. Left click on an Insert space and select Earlier VST Plug-ins, Lexicon, and Pantheon.
5. Select Lexicon and Pantheon.
6. Because this is an insert effect, move the Mix slider to 50% (see the Pantheon manual for more details).
7. Change the level to about -52dB. Now you will record with the Lexicon Pantheon Reverb on your track.

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 buffer 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 4 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 Vista and xp
1. Open Cubase LE 4 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. Moving the Lambda Stream Reliability slider toward More CPU will decrease any monitoring latency. If audio playback has artifacts (clicking, popping), move this slider toward Less CPU until it stabilizes. 4. When you are finished adjusting the buffer size, click the OK button and return to your project to test the results.
B. Adjusting the Buffers in MAC osX
