3.Connect the MONITOR A output jacks on the 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

control above the MONITOR A output jacks to the appropriate position. Otherwise, leave it at the –10 dBV position for now. You can con-

nect additional speakers to the MONITOR B and MONITOR C output jacks so you can hear your mix through different types of speakers.

4.If you have a separate studio for recording,

connect the STUDIO OUTS 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 in studio for the talent.

Set the trim control above the STUDIO OUTS output jacks to the appropriate position, or leave it at the –10 dBV position if you’re not sure.

5.If you have a headphone distribution amplifier for monitoring while recording, connect the

PHONES AMP output jacks to the inputs of the headphone amp. Set the +4/–10 level

switch above the PHONES AMP output jacks to the appropriate position, or leave it at the –10 position (pushed in) if you’re not sure.

For Recording

6.Connect the 2-TRACK A outputs to the line- level inputs of any recording device, like a DAT or cassette recorder. This allows you to record from your DAW to the recorder. Set the +4/–10

level switch above the 2-TRACK A output jacks to the appropriate position, or leave it at the –10 position (pushed in) if you’re not sure.

7.Connect the line-level outputs from the DAT or cassette recorder to the 2-TRACK A inputs.

8.Connect the DAW output jacks on the rear panel of Big Knob to the stereo inputs of your DAW’s audio interface. This allows you to record from the 2-TRACK recorder back to your

DAW. Set the +4/–10 level switch above the DAW output jacks to the appropriate position, or leave it at the –10 position (pushed in) if you’re not sure.

Set the Levels

1.With everything off, turn on Big Knob’s POWER

switch first.

2.Turn on all other external power amplifiers, active speakers, and headphone amplifiers.

3.Start playback on your DAW and play some- thing you’ve already recorded (or a demo track). You want to be able to listen to it over the moni- tor speakers connected to Big Knob.

4.Press the DAW MIXbutton in the INPUT SOURCE SELECT section on the front panel. The LED above the DAW MIX button should light.

5.Press the MONITOR A button in the MONITOR SELECT section on the front panel. The LED above the MONITOR A button should light.

6.If you know whether your DAW’s audio inter- face output is at a –10 dBV level (consumer) or a +4 dBu level (pro), set the +4/–10 level switch

for the DAW MIX inputs to the appropri- ate position. If you don’t know, leave it out (in the +4 dBu position). We can change it later if we need to.

7.Slowly turn up the trim control for the DAW MIX input until you see the meters on the front panel lighting and dancing happily. Adjust the control until the meters are lighting the “0” LED regularly. You want the “+8” LED to light only occasionally, and the “OL” LED to not light at all.

8.If you can’t adjust the trim control far enough to get the signal level up to the 0 and +5 LEDs on the meter, turn the trim control all the way down, push in the +4/–10 level switch for the DAW MIX input, and slowly turn up the trim control again. Now the signal should be strong enough to get the 0 and +5 LEDs to light.

9.Slowly turn up the Big Knob VOLUME control. You should begin to hear playback from your DAW through your studio monitor speak- ers. Adjust the VOLUME control to a comfort- able listening level. If it seems like you have to turn up the VOLUME control all the way to hear the monitor speakers, turn down the VOLUME control and check to see if the trim control
