[. . . ] Owner's Manual Complete reCording solution IMPORTANT SAFETY INSTRUCTIONS WARNING FOR YOUR PROTECTION READ THESE INSTRUCTIONS: KEEP THESE INSTRUCTIONS HEED ALL WARNINGS FOLLOW ALL INSTRUCTIONS The symbols shown above are internationally accepted symbols that warn of potential hazards with electrical products. The lightning flash with arrowpoint in an equilateral triangle means that there are dangerous voltages present within the unit. The exclamation point in an equilateral triangle indicates that it is necessary for the user to refer to the owner's manual. These symbols warn that there are no user serviceable parts inside the unit. [. . . ] 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. 12 Connecting to the Lambda Studio +48v PHANTOM POWER SWITCH IMPORTANT: Do not plug a line output into the Mic In jacks unless the +48 V (phantom) switch is turned OFF to avoid damage. 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. USB PORT The USB Port is used to connect the Lambda StudioTM to your computer and provides the Lambda Studio hardware with power. The Lambda Studio supports USB 2. 0 full speed. CONNECTINg TO ThE lAMbdA STUdIOTM 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 setups. This section describes how to make basic connections for the following applications: · 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 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 (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. 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. Adjust the Lambda Studio's output volume with the Output Level knob. If using 13 About Recording Connections 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 StudioTM 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. AbOUT 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. TO CONNECT A MICROPHONE 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. 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. [. . . ] 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. [. . . ]
