The installation and servicing instructions in this manual are for
use by qualified personnel only. To avoid electric shock, do not
perform any servicing other than that contained in the Operating
Instructions unless you are qualified to do so. Refer all servicing
to qualified service personnel.

Installation of 8200
Allow about 2 hours for installation.
Installation consists of: (1) unpacking and inspecting the 8200, (2) optional resetting of
jumpers for 8200 options (composite output impedance, input termination, input sensitiv-
ity), (3) checking the line voltage setting, fuses and power cord, (4) mounting the 8200 in a
rack, (5) connecting inputs, outputs and power, (6) setting the GROUND LIFT switch, (7)
optional connecting of remote control leads and (8) optional connecting of computer
interface control leads.
When you have finished installing the 8200, proceed to "System Setup," on page 2-41.
1. Unpack and inspect. (includes resetting option jumpers)
If you note obvious physical damage, contact the carrier immediately to make a damage
claim. Packed with the 8200 are:
1 Operating Manual
1 Line Cord
2 Fuses (F1 = 1/2A or 250mA
F2 = 4A or 2A, depending upon
specified mains voltage)
1 Extender Card
4 Rack-mounting screws, 10-32 x 1/2
-- with washers, #10
1 Hex wrench -- 1/8
1 BNC Cable -- 24 (60.96cm)
1 Orban green screwdriver (Xcelite R3323)
1 Booklet: Audio Quality in the FM Plant
A Save all packing materials! If you should ever have to ship the 8200 (e.g., for
servicing), it is best to ship it in the original carton with its packing materials because
both the carton and packing material have been carefully designed to protect the unit.
Re-package the unit according to Fig 2-1.
B Complete the Registration Card and return it to Orban. (please)
The Registration Card enables us to inform you of new applications,
performance improvements, and service aids that may be developed, and it
helps us respond promptly to claims under warranty without our having to
request a copy of your bill of sale or other proof of purchase. Please fill in
the Registration Card and send it to us today. (The Registration Card is
located after the cover page).
We do not sell our customer's names to anyone.

2. Change standard factory configuration, if required.
The 8200 is supplied from the factory with its jumpers set to the configuration correct
for most installations.
[Skip this step if your installation does not have any special requirements.]
A Set stereo encoder composite output impedance.
[Skip this step if your installation does not need 75 source impedance.]
The stereo encoder is shipped from the factory with 0 source impedance.
This is correct for virtually all installations. However, the 8200 stereo
encoder can be changed to 75 source impedance if desired.

The frequencies in the stereo baseband are low by comparison to RF or
video, and the characteristic impedance of coaxial cable is not 75 at lower
frequencies, so the transmission system will have more accurate amplitude
and phase response (and thus, better stereo separation) if the cable is driven
by a very low source impedance (0) and is terminated with greater than
1k at the exciter.
However, a few broadcast organizations require that FM composite be
transmitted in impedance-matched coaxial cable with 75 source and load
impedances.
2-6 INSTALLATION OPTIMOD-FM 8200
To change the source impedance of one or both of the composite
outputs:
Make sure that power is off before removing or inserting circuit cards.
Remove the stereo encoder board (the second card from the left) from the
chassis.
To change the source impedance of composite output #1 (the upper BNC
connector on the 8200's rear panel), move jumper JC to the "75" position
(Fig 2-3). To change the source impedance of composite output #2 (the
lower BNC connector on the 8200's rear panel), move jumper JD to the
"75" position (Fig 2-3). Then replace the card and close the chassis.
B Set analog left/right input termination.
[Skip this step if your installation does not require 600 termination on
the analog left/right inputs.]
The analog left/right inputs are shipped from the factory with balanced
bridging (10k) input impedance. However, the 8200 analog inputs can be
changed to 600 input impedance.
To change the input impedance of the analog left/right inputs:
Make sure that power is off before removing or inserting circuit cards.
Remove analog I/O board (the first card from the left) and move jumpers
JA and JB according to Figure 2-4. Jumper JA sets the right channel and
jumper JB sets the left channel.
