B)
Feed normal program material to the 9300.
C)
Play program material from your studio, peaking at normal program levels
(typically 0 VU if your console or mixing desk uses VU meters).
D)
[Skip this step if you are not using the analog input.]
Hold down the
A
NALOG
soft button and adjust the knob so that the
AGC
meter indicates an average of 10 dB gain reduction.
E)
[Skip this step if you are not using the digital input.]
Hold down the
D
IGITAL
soft button and adjust the knob so that the
AGC
meter indicates an average of 10 dB gain reduction.
12.
Set the digital output sample rate.
A)
Press the
N
EXT
button.
B)
[Skip this step if you will not be using the digital output(s).]
Turn the knob to set the Digital

to 32, 44.1, 48, 88.2,
or 96 kHz.
The internal sample rate converter sets the rate at the 9300’s digital out-
puts. This adjustment allows you to set the output sample rate to ensure
compatibility with equipment requiring a fixed sample rate. In all cases,
the 9300’s sample rate is 32 kHz and multiples thereof up to 128 kHz.
13.
Prepare to set output levels.
A)
Press the
N
EXT
button.
The positive peak threshold for all outputs is now set to 100%.
You can set asymmetry as desired after you have completed Quick Setup.
The
P

control in the active system preset determines asymme-
try. For Quick Setup, the active system preset is
TX1/D
AY
.
You can use either program material or tone to set the output level (and
thus, the on-air modulation).
To use tone, press the
Y
ES
button.
To use program material, press the
N
O
button.
We recommend using program material because it automatically takes
into account any bounce, overshoot, and ringing in the transmission
plant. A tone setup can cause overmodulation with program material un-
less the modulation control in your facility is “textbook perfect.”
14.
Set the digital output level.
A)
Press the
N
EXT
button.
B)
[Skip this step if you are not using the digital output.]
Turn the knob to set the desired digital output level corresponding to
100% modulation, in units of dB below full-scale.
