1. Power Connector For the most part, the rear panel is where to connect various sources feeding IN to the Big Knob. These signals are then routed through the Big Knob and released through the OUTPUT jacks. There are a few other bells and whistles, as well, and we’ll take a look at all features, no matter how great or small. We should probably start with how to power the darn thing up first, though...! 3 USB 4 REC SRC SELECT 2-TRACK INPUTS 1/2 POWER 2 +18VDC 1.
Big Knob Studio & Studio+ Monitor Controller | Interface 4. USB Rec Src Select Switch You want options, you’ve got options! The Big Knob Studio and Big Knob Studio+ grant you the opportunity to choose between recording paths for a multitude of applications, one of which is yours! This two-position latching switch simply allows you to choose which USB source you would like to use for recording: With the switch disengaged [2-track], the signal at the 2-track and monitor outputs is recorded.
8. Aux Mix | Cue In 1/4" Inputs [Big Knob Studio+] Connect the L/R line-level signals from the source(s) to the 1/4" source input jack(s). These 1/4" inputs are extremely powerful! Our favorite way to utilize them is by connecting the L/R outputs of an analog mixer to these L/R line-level input jacks. This way, multiple inputs (from the mixer) are all dialed into a stereo pair into the L/R aux mix | cue in jacks. • The source input connectors accept balanced or unbalanced signals.
Big Knob Studio & Studio+ Monitor Controller | Interface 10. Talkback Int / Ext Switch [Big Knob Studio+] Outputs Overview If you are in a noisy environment, the built-in talkback mic may not work as well because it picks up the ambient noise as well as your voice. You will probably have better results if you use an external microphone that you can talk directly into. All Big Knob outputs are 1/4" L/R connectors that may be distributed to a variety of inputs as outlined on the right.
This two-position switch sets the level of the 2-track outputs to either +4 dB (balanced output, switch disengaged) or –10 dB (unbalanced output, switch engaged). 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.
