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
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
that the AGC function in the 8300 continues to work). The Orban 4000 is
