Rear Panel Description
The rear panel is where to connect various sources
feeding IN to the Big Knob Passive. These signals are
then routed through the Big Knob Passive and released
through the monitor OUT jacks.
1. 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 connectors are wired as follows (per the AES/IEC
standard):
Balanced 1/4" TRS
Hot (+) Tip
Cold (–) Ring
Shield (Ground) Sleeve
Unbalanced 1/4

2. 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.
The Source Input B 1/4" and 1/8" line-
level connections may be connected
simultaneously. If both inputs are
connected simultaneously, the 1/8" stereo
line input will take priority over the 1/4" connection.
3. 1/4" Mon Outputs
Connect the L/R mon outputs to the inputs of powered
studio monitors or to a power amplifier driving passive
speakers.
The mon outputs are fed by the “control room bus.”
This is the signal path fed from the source input
currently selected with the source select button and
routed through the volume knob.
• The mon output 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 connectors are wired per the AES/IEC standard
as seen in the illustrations to the left.
