Factory Test Presets

Factory Test Presets include TO USER TONE and BY BYPASS. But unlike Factory
Processing Presets, the settings of Factory Test Presets can be changed, and these changes
are remembered in the Factory Test Preset. For example, you use the TO USER TONE
preset in the same way that you use any normal oscillator. Set the frequency and level, and
they remain that way until you change them.

User Presets

User Presets permit you to change a Factory Processing Preset or a Factory Test Preset to
suit your requirements, and store those changes. You may store up to 32 User Presets. They
are indicated on the RECALL PRESET list by a number designation from 01 to 32, followed
by a description. You may enter in any description you wish, up to 16 characters.
User Presets cannot be created from "scratch." You must always start by recalling a Factory
Preset. You can then immediately store this in a User Preset, give it whatever name you
wish, then make changes to the settings. Or you can recall a Factory Preset, make the
changes, then store this in a User Preset.
Either way, the Factory Preset remains for you to return to if you wish.

Input/Output Configurations

The OPTIMOD-FM 8200 DIGITAL is designed to simultaneously accommodate:
•
analog left/right inputs and outputs
•
stereo analog baseband composite output
•
Digital AES/EBU left/right inputs and outputs.
Each of these is accomplished with a plug-in card. The standard configuration includes
analog in/out and stereo composite out. AES/EBU in/out is accommodated by a separate
optional, user-installed card, available from your dealer.

Analog Left/Right Input/Output

The left and right analog inputs are on XLR-type female connectors on the rear panel. Input
impedance is greater than 10kΩ; balanced and floating. Inputs can accommodate up to
+27dBu (0dBu = 0.775Vrms). The left and right analog outputs are on XLR-type male
connectors on the rear panel. Output impedance is 30Ω; balanced and floating. Outputs can
drive up to +24dBm into 600Ω.
Level control of the analog inputs and outputs is via software control through SYSTEM
SETUP. (See page 2-41 and 2-55.)
Provided that the Analog I/O Card is installed, the left and right analog outputs are always
available regardless of whether the Stereo Encoder Card and/or Digital I/O Card is installed.
