2.4 Input Connections
The baseband audio input connects to
(A12) the A/V input and remote interface
assembly. The baseband audio connects
to TB1 for balanced audio or to jack J6
for composite, stereo, audio. The
baseband video input connects to jack
J2. NOTE: If another transmitter is
using the same composite audio and
video inputs, the loop through
connections on the rear of the VHF
exciter can be used. The video can be
connected to J2 and the composite audio
to J13.
NOTE: If your transmitter contains a
precise frequency kit, a 5/10 MHz
reference input must be connected to the
BNC jack J19 on the remote interface
assembly.
NOTE: If your transmitter contains a
receiver tray the RF input connects to the
“N” connector J1 or the “F” connector J18
on the remote interface assembly.
If the (A12) A/V input and remote
interface panel is not present in your
system, the baseband video and audio
inputs connect directly to the rear of the
VHF exciter.
NOTE: If your transmitter does not
contain the 4.5 MHz composite input kit,
the following description does not pertain
to your transmitter. The baseband video
input or the 4.5-MHz composite input
connects to jacks J1 or J2, which are
loop-through connected. The baseband
audio input connects to TB1 for balanced
audio or to jacks J3 or J13, which are
loop-thru connected, for composite,
stereo, audio. To use the (Optional) 4.5-
MHz composite input kit, the baseband
audio can remain connected to the VHF
exciter even if the 4.5-MHz composite
input kit is used, but the baseband video
must be removed from J1 or J2 and the
4.5-MHz composite input must be
connected to J1 or J2. The baseband
select command must be removed from
J7-6 and J7-7.
2.5 Remote Connections
The remote connections listed in Table 2-
10 are made to the (A12) A/V input and
remote interface assembly. The remote
connections are made to the 37 pos “D”
connector J9 or the 25 pos “D” connector
J10 on the assembly. Refer to the
interconnect drawing (1304391) to
confirm the remote pin connections.
