OPERATION ORBAN MODEL 8600Si
In this case, the enhancer prevents further enhancement in order to pre-
vent excess L–R energy, which can increase multipath distortion.
The stereo enhancer has the following controls:
Amount sets the maximum spatial enhancement.
Enhancer In / Out bypasses the stereo enhancer.
O
UT is equivalent to setting the
A
MOUNT to 0.
L-R / L+R Ratio Limit sets the maximum amount of enhancement to limit the
amount of multipath distortion that the stereo enhancement can add. However, if
the original program material exceeds this limit with no enhancement, the enhancer
will not reduce it.
Diffusion applies only to the
D
ELAY
enhancer. This control determines the amount
of delayed L–R added to the original signal.
Style sets one of two stereo enhancer types:
222
or
D
ELAY
.
Depth sets the delay in the delay line. It applies only to the
D
ELAY
enhancer.
AGC Controls
The AGC is common to the two-band and Five-Band structures.
These controls are available only from 8600Si PC Remote. However, if you wish to
turn off the AGC on all presets, you can use the global
AGC ON/OFF
setting avail-
able in Setup from the front panel.
These controls are explained in detail below.
Each Factory Preset has a
L
ESS
-M
ORE control that adjusts on-air loudness by altering
the amount of processing.
L
ESS
-M
ORE simultaneously adjusts all of the processing
controls to optimize the trade-offs between unwanted side effects.
