3. Connect the MONITOR A output jacks rear panel of Big Knob to a pair of active studio monitors (or the inputs of an amplifier that is powering a pair of passive studio monitors). These will be located at your mixing position. If you know whether the inputs to the active studio monitors (or amplifier) accept a –10 dBV (consumer) or +4 dBu input level, set the trim...

Big Knob Features Front Panel INPUT SOURCE SELECT Section These buttons turn on or off the four input signals connected to Big Knob. Any combination of the four inputs can be turned on at the same time, as indi- cated by the red LEDs above the buttons. When selected, these input sources are routed to the MONITOR A, B, and C stereo outputs, the 2-TRACK A and 2-TRACK B stereo outputs, the DAW stereo...
Pressing this button turns down the signal going to the MONITOR A, B, and C outputs by 20 dB. This lets you turn down the speakers to converse with- out affecting the speaker level you have set. Note: Like the Big Knob VOLUME control, the MONO, MUTE, and DIM buttons ONLY affect the MONITOR A, B, and C outputs.
When the button is down (PHONES MIX INPUT), the STUDIO/PHONES outputs are fed the signal from the DAW PHONES MIX INPUT rear panel. 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).

2-TRACK A Level Switch This two-position switch sets the input level of the 2-TRACK A inputs to either +4 dB (balanced input) or –10 dB (unbalanced input). 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.
For example, the DAW’s 1-2 outputs can send the main mix to the DAW MIX inputs on Big Knob, and the DAW’s 3-4 outputs can send a custom head- phone mix to the DAW PHONES MIX INPUT. You can then use the PHONES/STUDIO OUTS SOURCE button to select the mix for the PHONES and STUDIO OUTS DAW PHONES MIX Level Switch...

PHONES AMP and STUDIO OUT The PHONES AMP and STUDIO OUTS have the option of being fed signal by the currently selected INPUT SOURCE SELECT buttons (thus mirroring the mix being heard by the engineer) or the signal connected to the DAW PHONES MIX INPUT con- nectors (thus providing a separate unique monitor- ing mix for the talent).
