Preamp - Boss BR-1180 Owner's Manual

Insert effect parameter functions
Pitch
Adjusts the amount of pitch shift (the amount of pitch
change) in semitone steps. By selecting "DETUNE," you can
add a slightly pitch-shifted sound to the input sound,
producing a detune effect.
* This effect can be used when the "P.Shift Type" parameter is
set to "MANUAL."
D:E Balance
This adjusts the volume balance of the direct and effect
sounds.
Separation
Adjusts the diffusion. The panning of the direct sound and
effect sound can be spread to left and right. This will be
effective when stereo output is used.

* When all Bass, Middle and Treble are set to "0," no sound
may be produced depending on the "Amp Type" setting.
