48V PHANTOM
Some professional-quality microphones require an external (phantom) 48-volt DC power source for proper operation, so this
switch makes it possible to deliver that power to any microphone plugged into the Aux/Mic In jack. If you are not sure whether
your microphone requires phantom powering, check with your mic's user's manual or consult its manufacturer.
AUX/MIC IN
The Aux/Mic In is an electrically balanced input designed to accept low-impedance microphones or pro-level sound sources.
GND LIFT
When connecting the Channel 1 Send to other gear, it's possible that it can create a secondary path to ground, introducing hum
to the sound. Using the Gnd Lift (Ground Lift) switch disconnects the secondary ground path, removing the ground loop and the
hum that comes from it.
SEND (PRE-EQ)
This balanced XLR jack passes the signal entering Channel 1's input on to other gear, such as P.A. systems or recording mix-
ers. It is pre-EQ, meaning that it has not passed through the Bass, Mid, or Treble controls.
NOTE: The signal from the Send jack is electronically buffered, meaning that it is designed to drive other gear without a degra-
dation in the tone and overall signal quality. Its output strength is not affected by the Level control, but it is affected by the Trim
control.
EFFECTS SEND
The Effects Send is an electronically buffered output that sends part of Channel 1's signal to a signal processor (or effect
pedal). The sound sent from this jack is post-EQ, meaning that it is affected by any changes made via the Bass, Mid, or Treble
controls.
NOTE: The Effects Send can be used as a post-EQ output to drive other amplifiers or to send to mixers. It is not necessary to
have a plug in the corresponding Effects Return jack.
EFFECTS RETURN
The Effects Return jack accepts the return signal from a signal processor placed in the Effects Loop of Channel 1.
NOTE: If you are using another signal processor in the Channel 2 effects loop (or the second channel of a dual-channel signal
processor), make sure that the correct output jacks from the processor are connected to Channel 1's and Channel 2's Effects
Return jacks.
