When finished, reset
E
XT
AGC
to
Y
ES
, if required (e.g., if that was its setting
prior to setting
AI
R
EF
(VU or PPM) level).
Refer to step 1 on page 2-24.
4.
Adjust Right Channel Balance.
[Skip this step if the channels are already satisfactorily balanced.]
[
3 dB to +3 dB] on right channel only, 0.1 dB steps
Adjust the
R
C
H
B
AL
control to achieve correct left/right channel balance.
This is not a balance control like those found in consumer audio prod-
ucts. This control changes gain of the right channel only. Use this control
if the right analog input to the 8300 is not at exactly the same level as
the left input. Be certain that the imbalance is not caused by one pro-
gram source, but is instead introduced through distribution between the
console output and 8300 input. This adjustment is best accomplished by
playing program material that is known to be monophonic or by setting
the mixing console into mono mode (if available).
5.
Adjust the Digital Input Reference Level and Right Balance controls.
[Skip this step if you will not be using the digital input.]
A)
Navigate to
S
ETUP
/
IO
C
ALIB
/
D
IG
I
N
C
ALIB
/
I
NPUT
and set the input to Digital.
B)
Repeat steps 1 through 4 (starting on page 2-24), but use the
DI
R
EF
(VU
OR
PPM)
and
R
CH
BAL
controls for the digital section.
6.
Configure Composite Outputs
A)
Navigate to
S
ETUP
/
S
TEREO
E
NCODER
/
N
EXT
/
P
RE
-E
MPH
. Set the pre-emphasis
to 50
µ
s or 75
µ
s, depending on your country’s standard.
B)
Set
PILOT
LVL
to
9%
.
If you have to reduce the setting of the
C
OMPOSITE
L
EVEL
control to ac-
commodate overshoots in the transmission path following the 8300 (in-
cluding the transmitter), you may have to increase the setting of the
P
ILOT
L
EVEL
so that the pilot is still at 9% modulation.
C)
Press the
N
EXT
button. Be sure that
M
ODE
is set to
S
TEREO
and
X
TALK
T
EST
is set
to
O
PERATE
.
Reset these parameters if necessary.
D)
Using the
C
OMP
1
L
VL
and
C
OMP
2
L
VL
controls, adjust the level for each com-
posite output to produce 100% modulation of the FM carrier on modulation
peaks.
Alternately, you can use the 8300’s built-in calibration tone oscillator. To
do this:
a)
Navigate to
S
ETUP
/
T
EST
.
b)
Set the
M
ODE
to
T
ONE
.
c)
Set
T

F
REQ
to
400
