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 headphone 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

This two-position switch sets the input level of the DAW PHONES MIX inputs to either +4 dB (bal- anced input) or –10 dB (unbalanced input). Use the +4 dB setting for professional equipment or sound- cards operating at the +4 dBu standard, and use the

–10 dB setting for consumer equipment or sound- cards operating at the –10 dBV standard.

TALKBACK FOOTSWITCH

This 1/4-inch TS connector accepts a standard momentary footswitch (normally open), or a momentary handheld switch such as the Switchcraft ED900. This allows a producer standing at a remote location to activate the talkback circuit and communicate with recording talent.

When an external switch is connected and goes from its “normally open” position to its “momentary closed” position, the front panel TALKBACK TO 2-TRACKS

and TO PHONES/STUDIO buttons both activate, their LEDs illuminate, and the talkback circuit is activated just as if someone had physically pressed these two buttons. See “Appendix B: Connections” for a wiring diagram of the footswitch connection.

OUTPUTS

The following outputs are fed by the “control room bus.” This is the signal path fed from the inputs currently selected with the INPUT SOURCE SELECT buttons and routed through the Big VOLUMEKnob.

MONITOR A OUTPUTS

These stereo 1/4-inch balanced/unbalanced outputs connect to the first set of external speakers. You can connect these outputs to self-powered speakers, or to a power amplifier driving passive speakers.

MONITOR A Trim Control

This trim control adjusts the sensitivity of the MONITOR A output signal. Use the +4 dB setting when connecting to balanced inputs on professional equipment operating at the +4 dBu standard, and use the –10 dB setting when connecting to unbalanced inputs on consumer equipment operating

at the –10 dBV standard. The trim control can be adjusted to any setting between the +4 and –10 positions if necessary to precisely match the levels among the MONITOR A, B, and C outputs.

MONITOR B OUTPUTS

Works as described above for the Monitor A path.

MONITOR B Trim Control

Works as described above for the Monitor A path.

MONITOR C OUTPUTS

Works as described above for the Monitor A path.

MONITOR C Trim Control

Works as described above for the Monitor A path.

Note: The overall level of the MONITOR A, B, and C OUTPUTS is controlled by the Big VOLUMEKnob on the front panel.

2-TRACK A OUTPUTS

These stereo 1/4-inch balanced/unbalanced outputs connect to the inputs of the first external 2-track recorder. This could be a DAT deck, cassette deck, reel-to-reel recorder, etc. The signal at these outputs is whatever source is selected with the INPUT SOURCE SELECT buttons on the front panel.

2-TRACK A Level Switch

This two-position switch sets the level of the 2-TRACK A outputs to either +4 dB (out) or –10 dB (pushed in). Use the +4 dB setting when connecting to balanced inputs on professional equipment operating at the

+4 dBu standard, and use the –10 dB setting when connecting to unbalanced inputs on consumer equipment operating at the –10 dBV standard.

2-TRACK B OUTPUTS

Works as described above for the 2-TRACK A OUTPUTS.

2-TRACK B Level Switch

Works as described above for the 2-TRACK A level switch.

DAW OUTPUTS

These stereo 1/4-inch balanced/unbalanced outputs connect to a pair of inputs on the DAW audio interface.

DAW Level Switch

This two-position switch sets the level of the DAW outputs to either +4 dB (out) or –10 dB (pushed in). Use the +4 dB setting when connecting to balanced inputs on professional equipment or soundcards operating at the +4 dBu standard, and use the –10 dB setting when connecting to unbalanced inputs on consumer equipment or soundcards operating at the –10 dBV standard.

By allowing balanced or unbalanced operation, as well as –10 or +4 operation, on an individual basis, you can connect any combination of professional or consumer

2-track recorders and DAW soundcards that you have available in your arsenal of audio recording equipment.

Note: All three of the above out-

puts (2-TRACK A, 2-TRACK B, and

DAW) produce the signal selected by the INPUT SOURCE SELECT buttons on the front panel. These

outputs require no variable level output controls (aside from the +4/–10 switches), since the connected 2-track recorders and DAW inputs typically have their own variable input level controls.
