Electro-Harmonix TRI PARALLEL MIXER Manual page 3

OUTPUT – This jack on the left of the unit is the master output for the
Tri Parallel Mixer.
MASTER VOL – This knob sets the master output level of the mixer.
DRY VOL – This knob sets how much dry signal (the signal present at
the INPUT jack) is sent to the output of the Tri Parallel Mixer.
MASTER STATUS – This LED lights when the unit is active and doesn't
light when in master bypass. Double tap any of the three footswitches
to switch from active to bypass mode. When in bypass, single tap any
footswitch to enter active mode. The Tri Parallel Mixer features buffered
bypass.
RETURN Knob – This knob sets the level of the signal received at the
RTN jack before it is sent to the output of the Tri Parallel Mixer.
PHASE – This switch, when set to 180, inverts the phase of the signal
sent out of the SEND jack. This can be useful when something in your
effects loop is causing phase issues when mixed in with either your dry
signal or other effects loops.
-CHANNEL CONTROLS / JACKS-
The majority of the controls for the Tri
Parallel Mixer are grouped into three
identical channel sections, each with a
SEND and RTN (Return) jack, a SEND and
RETURN level control, an EQ control, a
PHASE switch, and a footswitch.
SEND 1/2/3 Jack – This jack outputs the
signal inputted to the Tri Parallel Mixer (via
the INPUT jack) when its channel is
active*. Send output impedance = 220Ω.
SEND Knob – This knob sets the level
outputted to the SEND jack.
RTN 1/2/3 Jack – This jack is the input
for a given channel. The signal inputted to
this jack is sent to the OUTPUT jack (after
the EQ control) when its channel is
active*. RTN input impedance = 1MΩ.
