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 
outputs and, when the PHONES/STUDIO OUTS 
SOURCE button is out (INPUT SOURCES), to the 
PHONES AMP and STUDIO OUTS stereo outputs, and 
to the PHONES 1 and 2 outputs on the front panel.
A Cautionary Note:
 When you 
have a 2-track recording device 
connected to both the inputs and 
the outputs on Big Knob, you run 
the risk of creating a feedback 
loop. If the recording device is in record, record 
pause, or input monitor mode, the signal can go 
from the 2-TRACK outputs through the recording 
device and back into the 2-TRACK inputs, creating 
a circular loop that results in a terrible howl. 
You must remember to turn off the 2-TRACK 
INPUT SOURCE SELECT button when recording 
to your 2-track recorder!
 DAW MIX
Turns on the signals connected to the DAW MIX 
stereo inputs.
 2-TRACK A
Turns on the signals connected to the 2-TRACK A 
stereo inputs. 
 2-TRACK B
Turns on the signals connected to the 2-TRACK B 
stereo inputs. 
 PHONO
Turns on the signals connected to the PHONO ste-
reo inputs.
 INPUT METERS
These six segment meters show the signal level of 
the currently selected stereo source(es). The scale 
of the six segments of the meter is: 
–24, –8, –4, 0, +8, and OL (Overload), where “0” is 
referenced to +4 dBu.
 VOLUME
This Big Knob adjusts the volume of the selected 
input source going to the selected speaker outputs 
(MONITOR A, B, and C). The VOLUME knob ONLY 
affects the volume level of the monitor outputs (A, 
B, and C). It does not affect the volume of the signal 
going to other outputs, such as the headphone out-
puts, 2-TRACK outputs, or DAW outputs.
The VOLUME knob ranges from OFF (
∞) to +10 dB 
of gain (MAX).
 MONO
Pressing this button combines the stereo signal 
into a monophonic signal at the MONITOR A, B, 
and C outputs. The left and right input signals are 
summed and the mono signal is output at both the 
left and right outputs. This lets you check for phase 
problems in the stereo signal when played over a 
monophonic system.
 MUTE
Press this button to mute the signal going to the 
MONITOR A, B, and C outputs.
