OPTIMOD-FM INTRODUCTION
1-5
• OPTIMOD-FM can increase the density and loudness of the program material by
multiband compression, limiting, and clipping — improving the consistency of the
station’s sound and increasing loudness and definition remarkably, without producing
unpleasant side effects.
• OPTIMOD-FM rides gain over an adjustable range of up to 25 dB, compressing dy-
namic range and compensating for both operator gain-riding errors and gain inconsis-
tencies in automated systems.
• OPTIMOD-FM’s Two-Band processing structure is phase-linear to maximize audi-
ble transparency.
Controllable
• OPTIMOD-FM can be remote-controlled by 5-12V pulses applied to eight pro-
grammable, optically isolated ports.
• OPTIMOD-FM is equipped with a serial port to interface to an IBM-compatible
computer running Orban’s PC Remote software. The connection can either be direct
or through an external modem.
• OPTIMOD-FM has a second serial port that allows the user to set up security and
communications parameters through a simple ASCII terminal program running on
any PC. It also permits simple ASCII strings to trigger preset recall, facilitating inter-
face to automation systems that can emit such strings through an RS232 serial port.
• OPTIMOD-FM can be connected to a TCP/IP network through an optional rear-
mounted Ethernet PC card.
• A Bypass Test Mode can be invoked locally or by remote control to permit broadcast
system test and alignment or “proof of performance” tests.
• OPTIMOD-FM's software can be upgraded remotely through its
Serial 1 port (con-
nected to an external modem) or PC-Card Port (via an optional Ethernet card), or lo-
cally (by connecting a Windows® computer to its
Serial 1 port through the supplied
null modem cable) and running Orban-supplied downloadable upgrade software.
• OPTIMOD-FM’s user presets can be saved, recalled, and archived through its PC
Remote software or to a PC-Card memory card plugged into its front PC Card port.
• OPTIMOD-FM Audio Processor contains a built-in line-up tone generator, facilitat-
ing quick and accurate level setting in any system.
• The 8400 Audio Processor contains a versatile real-time clock, which allows automa-
tion of various events (including recalling presets) at pre-programmed times.
