(B)-Effects Loop
Using the Loop:
When inserting a device like an equalizer, or perhaps a Sonic Maximizer (or similar
processor), the loop should be set in series mode. The mix controls on the outboard
device can be used to control all effects and the balance between clean and dirty
effects.
Side-Chaining Effects:
For maximum signal purity and sound quality, when using effects like digital reverbs
and/or effects like an echo or tape delay, the loop can be used in parallel mode. In
this case, the effects should be run fully “wet” (no non-processed signals sent
through the effect). The send and returns of the loop are set for proper balance of
clean/effect and the controls on the effect can be used to trim the tone. This
method assures the clean (dry) non processed signal will remain in the amplifier, and
not be degraded by the outboard effect.
