Using the Effects loop
The AC75 and AC150 Acoustic Ribbon amplifiers feature rear panel PREAMP OUT and
AMP IN connectors that access the preamp section and power amp section sepa-
rately. They can be individual, for example the PREAMP OUT can be used to send the
signal to a recorder or AMP IN can be accessed for using the amp as a powered moni-
tor. But, a more common use is as an effects loop for an external processor. If you are
using the AC150, the effects can be returned in stereo since the left and right pairs of
5-inch full range speakers are powered by separate 50 watt amplifiers. Therefore, the
left side of the effects will be heard in the left pair of 5-inch full range speakers and
the right side of the effects will be heard in the right pair of 5-inch full range speak-
ers.
• Using a standard shielded instrument cable, connect the AC series rear panel PRE-
AMP OUT to the input of your signal processor.
• Now use a standard shielded instrument cable to connect the output of the signal
processor to the AC series AMP IN connector located on the rear panel.
• If you are using the AC150 with a stereo effect, you can return both the left and
right outputs from the signal processors to the AC150's LEFT and RIGHT AMP IN.
Note: If you are using a delay line effect like a reverb, flanger chorus, digital delay or multi-
effects, be sure to pay attention to the effect unit's MIX control so that you have both wet
and dry signal. Check the manual of your effects unit to learn how to set the MIX control.
