OPERATION ORBAN MODEL 8700i

Preset 4: A general-purpose preset that works well with most processing presets.
When on-air processing preset is designed well, it is still possible to stay at the
limit with nearly inaudible BS412 control up to 2dB gain reduction.

Preset 5: The controller gates on nearly every power-drop so that the release
rate is almost always very slow. Designed to act only as a protection limiter to
sound nearly like no BS412 controller is working at all while still getting loud-
ness benefits from it. BS.412 gain reduction of up to 3dB is possible without ob-
jectionable side effects.

Getting the Bass Sound You Want
Probably the most frequently asked question we get regarding 8700i setup is “How
do I get a (such-and-such) bass sound?” It seems that individual preference varies in
this area more than anywhere else.
There are no magic formulas. The 8700i has extremely versatile controls affecting
bass sound and will allow you to get almost any sound you want as long as that
sound respects the laws of physics—or, in this case, the laws of psychoacoustics.
