This section describes how to make basic connections for the following applications: · Monitoring Audio · Recording Audio · Connecting a Recorder for Mixdown MONITORINg CONNECTIONS The Alpha Studio allows you to monitor audio from both 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 10). You can listen to (monitor) the audio through either the 1/8" Headphone jack on the front panel, through studio monitors using the ¼" or RCA 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 on the front panel. Alpha Studio's ¼" 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 Alpha Studio. 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 Alpha Studio to the appropriate inputs on your mixer, power amp, or powered monitors. Adjust the Alpha 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 RCA OUTPUTS FOR MONITORING TO A HOME STEREO Connect the RCA Line Out 1-2 jacks on the rear panel of the Alpha Studio to the appropriate inputs on your stereo, typically the Tape In or Aux In jacks, using standard RCA cables. Keep the Output Level knob on the Alpha Studio low at first, raising it slowly to match the level of other units connected to the stereo. 13 About Recording Connections 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 Plug an XLR cable directly from a microphone into the Mic input on the Alpha StudioTM rear panel. [. . . ] When using Cubase LE's input software monitoring with the Alpha Studio, you will want to set the Monitor Mix knob all the way to the Playback side.
