OPERATION ORBAN MODEL 8600Si
To accommodate the FM pre-emphasis curve, Band 5 of the Five-Band
Structure is capable of 30 dB of gain reduction.
Further, be aware of the different peak factors on voice and music — if voice and
music are peaked identically on a VU meter, voice may cause up to 10 dB more peak
gain reduction than does music! (A PPM will indicate relative peak levels much more
accurately.)
The AGC meter can be switched (within the Full Control screens) so that it either
reads the gain reduction of the Master (above-200 Hz) band, or the difference be-
tween the gain reduction in the Master and Bass bands.
The latter reading is useful for assessing the dynamic bass equalization
that the AGC produces and it helps you set the
AGC BASS COUPLING
control.

You cannot give a user preset the same name as a factory preset. If the name
that you have selected duplicates the name of a factory preset, the 8600Si will
suggest an alternate name.
•
If the name you have selected duplicates the name of an existing user preset, the
8600Si warns you that you are about to overwrite that preset. Answer Y

wish to overwrite the preset and N
