Programmable, Controllable, Expandable - Orban OPTIMOD-FM 8200 Operating Manual

OPTIMOD-FM 8200
•
The Protection Structure is designed for stations wanting the highest possible
fidelity to the source, such as a station broadcasting concert music at night.
•
The 8200 applies to digital processing a distillation of Orban's sixteen years of
market-leading analog processing experience; the unit builds and improves on the
uniquely successful sound of the Orban analog processors.
•
All structures except the Protection Structure ride gain over a range of as much
as 25dB, reducing dynamic range and compensating for gain riding errors on the
part of operators. The amount of dynamic range reduction ordinarily produced is
adjustable.
•
The 8200 can be changed from one processing structure to another almost
instantly.
Programmable
•
The 8200 is supplied from the factory with factory-programmed presets for
virtually all program formats. Presets specify both a processing structure and its
control settings.
•
Factory Presets can be user-modified and stored in 32 user presets. They can be
recalled either locally or by remote control.
Controllable
•
The 8200 Audio Processor contains a versatile real-time clock, which permits
presets to be recalled at pre-programmed times.
•
All compression, limiting, and clipping can be defeated by remote control to
permit broadcast system test and alignment or "proof of performance" tests.
The 8200 Audio Processor is fully remote-controllable from an RS-232/RS-422
serial port (for computer or modem interface) using the optional 8200 PC Remote
Control Software, and by optically-isolated terminals that can be operated with
contact closures (to facilitate interfacing to older-technology remote controls).
Orban's optional 8200 PC Remote Control Program for IBM PC compatibles lets
you do everything from the remote computer that you can do from the 8200's
front panel.
•
The 8200 Audio Processor contains a built-in line-up tone generator, facilitating
quick and accurate level setting in any system, as well as a Bessel-null tone for
calibrating modulation.
•
The 8200 Audio Processor can produce the standard EBS (U.S. standard Emer-
gency Broadcast System) tones. It is FCC type accepted.
Expandable
•
The 8200 is expandable, so you can add more DSP processing power as needed
to accommodate future software upgrades and processing structures.
