2-2 INSTALLATION OPTIMOD-FM 2200
Installation of 2200
Allow about 2 hours for installation.
Installation consists of: (1) unpacking and inspecting the 2200, (2) optional resetting of
jumpers for 2200 options (composite output impedance, input termination, input sensitiv-
ity), (3) checking the line voltage setting, fuses and power cord, (4) mounting the 2200 in a
rack, (5) connecting inputs, outputs and power, (6) setting the GROUND LIFT switch, (7) and
optional connecting of remote control leads.
When you have finished installing the 2200, proceed to "System Setup," on page 2-16.
1. Unpack and inspect.
A If you note obvious physical damage, contact the carrier immediately to make a
damage claim. Packed with the 2200 are:
1 Operating Manual

B Save all packing materials! If you should ever have to ship the 2200 (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.

2. Change standard factory configuration, if required.
[Skip this step if your installation does not have any special requirements.]
The 2200 is supplied from the factory with its jumpers set to the configuration correct
for most installations.
Stereo Encoder Composite Output Impedance 0
Input Impedance 10k
Input Sensitivity -10dBu or greater (+5dBu to +27dBu peak)
A To change any jumpers you must remove the top cover of the 2200 to access the main
circuit board. (Make sure power is not connected.) Remove all screws holding the
cover in place, then lift it off. (Be careful not to strip threads when opening the
cover.)
B Refer to Figure 2-1 to find the jumpers on the main circuit board and to position them
according to your application.
The following information is provided to explain each jumper and its settings in detail.
