[. . . ] PHONES/STUDIO OUT SOURCE Button This button affects the stereo signal going to: · Both headphone outputs (PHONES 1 and 2) on the front panel · The PHONES AMP output on the rear panel · The STUDIO OUTS on the rear panel When INPUT SOURCE(S) is selected (up), the above outputs are fed the signal from the INPUT SOURCE SELECT buttons. In this position, the recording engineer and the talent can listen to the same mix (the MONITOR outs and STUDIO/PHONES outs have the same signal).

In this position, the recording engineer listens to the "real" mix coming from the DAW (DAW MIX INPUT), but the talent can listen to an alternate and specialized mix coming from the DAW (DAW PHONES MIX INPUT). Many DAW applications provide at least four outputs through their associated I/O hardware. Two outputs can provide the main mix, which is connected to the DAW MIX INPUTs on Big Knob and selected for monitoring with the DAW MIX INPUT SOURCE SELECT button. The engineer can create a separate headphone mix for the talent in the DAW application by using a stereo aux send routed to another pair of outputs, which is connected to the DAW PHONES MIX INPUT on Big Knob and routed to the STUDIO/ PHONES outputs with the PHONES/STUDIO OUT SOURCE button. STUDIO OUTS ON/OFF This button turns the signal path on and off going to the STUDIO OUTS jacks on the rear panel. When the button is pushed in (ON), the red LED above the button lights and the signal appears at the STUDIO OUTS. STUDIO OUTS LEVEL Control This controls the level at the STUDIO OUTS the rear panel. TALKBACK LEVEL This knob controls the level of the preamp for the internal omni-directional talkback mic, as it is routed either to the DAW and 2-TRACK A and B outputs (when the TO 2-TRACKS button is pressed) or to the PHONES/STUDIO bus (when the TO PHONES/STUDIO button is pressed). The gain of the TALKBACK LEVEL control ranges from Off () to +10 dB when turned all the way up. Internal Talkback MIC This omni-directional microphone is located right in Big Knob's front panel, just to the left of the Big VOLUME Knob. The microphone is activated when one of the two TALKBACK assign buttons is pressed. on TO 2-TRACKS Pressing this momentary button illuminates the red LED above it, activates the internal talkback MIC, and sends its signal to the: · 2-TRACK A output connectors · 2-TRACK B output connectors · DAW output connectors TO PHONES/STUDIO Pressing this momentary button illuminates the red LED above the button, activates the internal talkback MIC, and sends its signal to the: · PHONES 1 and 2 headphone outputs on the front panel · PHONES AMP outputs on the rear panel · STUDIO OUTS on the rear panel The TALKBACK TO PHONES/STUDIO button routes the talkback signal to all of these outputs no matter how the PHONES/STUDIO OUTS SOURCE selector button is set. This means that all the headphones and studio outputs will hear the talkback signal whether they are getting program material from the INPUT SOURCE(S) or the PHONES MIX INPUT . Unlike all of the other buttons, the TALKBACK TO PHONES/STUDIO and TALKBACK TO 2-TRACKS buttons are momentary, and only activate the talkback mic as long as they are physically pressed. Note: Both talkback buttons can be pressed at the same time to route the talkback mic to the 2TRACK outputs and the PHONES/STUDIO outputs. If the TALKBACK FOOTSWITCH jack on the rear panel is activated by an external footswitch, it is the equivalent of pressing both talkback buttons at once. Operation Guide RearPanel SOURCES The following section describes the connectors that are used for various sources feeding into Big Knob. 2-TRACK A Inputs These stereo 1/4-inch balanced/unbalanced inputs are fed by the outputs of the first external 2-track recorder. If a mono signal is plugged into the LEFT input only, it is automatically routed to both LEFT and RIGHT inputs.

Use the +4 dB setting for professional equipment operating at the +4 dBu standard, and use the ­10 dB setting for consumer equipment operating at the ­10 dBV standard. 2-TRACK A Trim Control This control adjusts the input sensitivity of the incoming 2-TRACK A signal by ±10 dB (unity at center detent).
