INSTALLATION
ORBAN MODEL 9300
a)
Press
E
SC
.
b)
Press
the soft key labeled with the system preset you wish to adjust.
c)
Adjust the filter frequencies as you did in the steps above.
7.
Configure analog output(s).
[Skip this step if you will not be using the analog output(s).]

If necessary, use the
N
EXT
button to scroll horizontally.
B)
Set the
L
OAD
control to
B
RIDGING
or
600
O
HMS
. The normal setting is
B
RIDGING
.
Only set this control to
600
O
HMS
if your transmitter has been verified to have
a 600-ohm input impedance.
Functionally, the control increases the output level by 4.0 dB when the
control is changed from
B
RIDGING
to
600
OHM
. This compensates for the 4
dB loss in the 9400’s EMI filtering network when this network is loaded
by 600 ohms.
If you are using Analog Output #2, navigate to Navigate to

.
If necessary, use the
N
EXT
button to scroll horizontally.
B)
Set the
P
RE
-E
MPH
control to
J.17
or
F
LAT
.
Almost all systems will require
F
LAT
output.
J.17
is only used if you are
driving a STL employing J.17 preemphasis (like certain NICAM STLs) and
you have bypassed the J.17 emphasis filter in the STL.)
C)
Set the
DO
R
ATE
to 32, 44.1, 48, 88.2, or 96 kHz.
The 9300’s fundamental sample rate is always 32 kHz. However, the in-
ternal sample rate converter sets the rate at the 9300’s digital output.
This adjustment allows you to set the output sample rate to ensure com-
patibility with equipment requiring a fixed sample rate.
D)
Set
F
ORMAT
to
AES3
or
SPDIF.
Professional equipment usually requires
AES3
.
E)
Set the desired output
W
ORD
L
EN
(word length).
[14], [16], [18], [20], or [24], in bits
The largest available word length is 24 bits. The 9300 can truncate its
output word length to 20, 18, 16 or 14 bits. The 9300 can add dither for
input material that is insufficiently dithered for these lower word lengths
(see the next step).
F)
Adjust
D
ITHER
to
I
N
or
O
UT
, as desired.
