6. 1/4" Source Inputs
Connect the L/R line-level signals from the source(s)
to the 1/4" source input jack(s).
• The source input connectors accept balanced
or unbalanced signals.
• Unbalanced TS (tip-sleeve) lines can be accommodated
via the TRS jack. Make sure the cable terminates with a
TS plug (like a guitar plug), or if it’s a TRS plug (such
as a headphone plug), make sure the ring is tied to the
sleeve and that the plug is fully inserted into the jack.
The left TRS inputs are mono-summing (to both
busses), but stereo when cables are connected to the
left and right inputs.
These 1/4" connectors are wired the same as the
combo input connectors as seen on the previous page.
There is an 1/8" stereo line input on the
front panel of both the Big Knob Studio
and Big Knob . 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 ].
The Big Knob Studio has one pair of 1/4"
source input jacks while the Big Knob
possesses an additional pair.
7. +4 dB / –10 dB Level Switch
This two-position switch sets the level of the source
inputs to 4 dB (balanced input, switch
disengaged) or –10 dB (unbalanced input, 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.
This switch sets the level for source inputs
3/4 on the Big Knob Studio and source
inputs 5/6 on the Big Knob .

8. Aux Mix | Cue In 1/4" Inputs [Big Knob ]
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.
Another possibility is connecting the outputs of a
soundcard to these inputs. Basically, any alternate mix
in from an external source is possible! This provides the
artist with a separate mix and may be thought of as USB
channels 3/4.
• The aux mix | cue in input connectors accept balanced
or unbalanced signals.
• Unbalanced TS (tip-sleeve) lines can be accommodated
via the TRS jack. Make sure the cable terminates with
a TS plug (like a guitar plug), or if it’s a TRS plug (such
as a headphone plug), make sure the ring is tied to
the sleeve and that the plug is fully inserted into the
jack. The left TRS inputs are mono-summing (to both
busses), but stereo when cables are connected to the
left and right inputs.
These 1/4" connectors are wired the same as
the 1/4" and combo input connectors seen previously.
Internal Talkback Mic (on Top Panel)
The built-in talkback microphone
is located on the Big Knob’s top panel
between the trim knobs and input
meters. It is an omni-directional dynamic
microphone, and will pick up your voice
from anywhere in front of the Big Knob.
It’s activated when a talkback assign
button is pressed [To 2-Track, To Cue].
9. Talkback Mic XLR Input [Big Knob ]
This XLR connector may accept a balanced external
dynamic mic for talkback. It is wired as follows,
according to standards specified by the AES (Audio
Engineering Society).
Balanced XLR Wiring:
Shield (Ground)
Pin 1
Hot (+)
Pin 2
Cold (–)
Pin 3
The talkback level is controlled by the
Talkback knob. Because the talkback knob
is located on the top panel of the Big Knob
, it will be described in more detail
in that section.
