FX LOOP:
SERIES Operation:
The SEND jack plugs into the effects unit's input jack. The SERIES
RETURN jack plugs into the effects unit's output jack. The audio path of
the amplifier is interrupted and 100% of the signal is being sent to the
SEND jack. The S.LEVEL control is used to adjust the amount of signal
being sent to an effects unit. With stomp box pedals there are usually no
input level indicators. In this case you will have to use your ears to set the
S.LEVEL. Set the S.LEVEL up to the maximum setting just before you
start to hear the undesirable front end clipping of your effects pedal. This
setting of the S.LEVEL will usually be quite low for pedals. Setting the
S.LEVEL for rack units is easier since they have input indicators.
PARALLEL Operation:
Your original, dry tone is unaffected allowing you to mix in the amount of
effects. The SEND jack plugs into the effects unit's input jack. The
PARALLEL RETURN jack plugs into the effects unit's output jack. The
S.LEVEL control is used to adjust the amount of signal being sent to an
effects unit. With stomp box pedals there are usually no input level
indicators. In this case, again, you will have to use your ears to set the
S.LEVEL. Set the S.LEVEL up to the maximum setting just before you
start to hear the undesirable front end clipping of your effects pedal. This
setting of the S.LEVEL will usually be quite low for pedals. Setting the
S.LEVEL for rack units is easier since they have input indicators.
NOTE: When using effect units in the FX LOOP in PARALLEL mode, you
must set the effects unit's mix control to 100%. By not doing so will cause
phasing issues. Using the FX LOOP in SERIES mode will send 100% of
the amp's signal out of the SEND jack. Please use caution as to the
quality of the effects unit you want to put your entire tone through. This is
a non "tone sucking" loop. If transparency is not achieved, then it is most
likely caused by improper setting or application of the FX LOOP.
Rear Panel Controls
RAW: Unfiltered raw signal tapped off the
loudspeakers jacks while amp is in operation
mode (off standby with speaker load
attached)This output can be fed to the slave
input/power amp in/Effects loop return of
another guitar amp or into the input of a power
amp.
EMULATED: Transformer isolated Emulation of a Randall speaker 4x12
cabinet. Prefixed output is dependent on the channel volumes and is post
fx loop and functions regardless of standby switch position.
GROUND LIFT: Lifts pin 1 on the EMULATED OUTPUT for ground loop
issues while interfacing with external equipment such as mixers, recording
interfaces or monitors.
