7.
Set external AGC mode.
Most of the processing structures in the 8300 control level with a preliminary
AGC (Automatic Gain Control). If you are using a suitable Automatic Gain Con-
trol at the studio (such as an Orban 8200ST OPTIMOD-Studio or 464A Co-
Operator), the AGC in the 8300 should be defeated. This is so that the two AGCs
do not “fight” each other, and so they do not simultaneously increase gain, re-
sulting in increased noise.
A)
Press the
N
EXT
button.
B)
Set external AGC mode by turning the knob.
Set the field to Yes if you have an external AGC (such as an Orban 1100,
1101, 6300, 8200ST OPTIMOD-Studio, Orban 464A Co-Operator, or similar
AGC) installed at your studio feeding the studio-to-transmitter link. This
setting appropriately defeats the 8300’s AGC for all presets.
Set the field to No If you do not have a external AGC installed; this setting
enables the 8300 AGC status to be determined by the selected preset.
If you are using an Orban 4000 Transmission Limiter, set field to
N
O
(so
that the AGC function in the 8300 continues to work). The Orban 4000 is
a transmission system overload protection device; it is normally operated
