13. +4 dB / –10 dB Level Switch
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.
14. 1/4" Studio/Phones Amp Outputs [Big Knob Studio
+
]
Connect the L/R studio / phones amp outputs to
EITHER...
...(1) the inputs of powered studio monitors
(or to a power amplifier driving passive speakers)
in the studio performance space. This allows the
performers to hear playback without having to use
headphones and allows the control room engineer
to communicate to the performers through the talkback
system. The studio outs level is controlled by the studio
outs level control on the front panel...
...OR (2) the inputs of an external multi-headphone
amplifier. This allows you to connect multiple sets
of headphones for the talent. The phones amp
output level is not affected by the volume knob
or the headphone level controls on the top panel.
The headphone amplifier should have its own
individual volume controls for the headphones.
15. 1/4" Monitor Outputs
Connect the L/R monitor outputs to the inputs
of powered studio monitors or to a power amplifier
driving passive speakers. These outputs deliver
the main balanced stereo signal (as determined
by the enagaged input selections)
.
The Big Knob Studio has two pairs of 1/4"
monitor output jacks while the Big Knob
Studio
+
possesses an additional pair.

Front Panel Description
The front panel may not have a ton of features – there
are only two – but we’re confident that the features
provided will be used often for years to come. That said,
we better take a look!
16. 1/8" Stereo Line Input
The stereo line input may accept an 1/8" line-level
signal from a smartphone, MP3 player, or other signal
source.
There are 1/4" inputs on the rear panel
of both the Big Knob Studio and Big Knob
Studio
+
. The 1/4" and 1/8" line-level
connections may be connected
simultaneously, but not used simultaneously. If they
are connected simultaneously, the 1/8" stereo line input
will take priority over the listed 1/4" connection [3/4
on the Big Knob Studio, 5/6 on the Big Knob Studio
+]
.
17. 1/4" Phones Jacks
These 1/4" TRS connectors supply the output to stereo
headphones. The volume is controlled with the phones
knobs located on the top panel. The signal sent to these
jacks is dependent on the position of the 2TR / CUE
switch as described on the following page.
The phones output follows standard conventions:
Left channel Tip
Right channel Ring
Ground Sleeve
The headphone amp is loud and could
cause permanent hearing damage. Even
intermediate levels may be painfully loud
with some headphones. BE CAREFUL!
Always turn the phones knob all the way down before
connecting headphones or doing anything new that may
affect the headphone volume. Then turn it up slowly as
you listen carefully.
