INTRODUCTION ORBAN MODEL 8600Si
Adaptability through Multiple Audio Processing Struc-
tures
•
A processing structure is a program that operates as a complete audio proc-
essing system. The 8600Si realizes its processing structures as a series of high-
speed mathematical computations made by Digital Signal Processing (DSP) chips.
•
The 8600Si features six processing structures. Four of these are the same as Op-
timod-FM 8500:
Five-Band (or “Multiband”) for a consistent, “processed” sound
with 17 ms delay (typical), free from undesirable side effects, Low-Latency
Five-Band (12 ms delay), Ultra-Low-Latency Five-Band (3.7 ms delay), and
Two-Band (17 or 22 ms delay) for a transparent sound that preserves the fre-
quency balance of the original program material. A special Two-Band preset cre-
ates a no-compromise “Protect” function that is functionally similar to the “Pro-
tect” structures in earlier Orban digital processors.
The 8600Si’s two
“MX” structures (five-band and two-band) are similar to
their 8500 counterparts except that they use the 8600Si’s new peak limiting
technology to
decrease distortion while achieving substantial improvements
in transient punch and high frequency clarity . This advanced technology re-
quires more input-to-output delay than the older structures, so it is impractical
for talent to monitor these structures off-air with headphones. The 8600Si offers
a special
low-delay monitor output for this purpose.
•
The 8600Si 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.
•
The 8600Si 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 in-
consistencies in automated systems.
•
The 8600Si’s Two-Band processing structures can be made phase-linear to max-
imize audible transparency.
Controllable
•
The 8600Si can be remote-controlled by 5-12V pulses applied to eight pro-
grammable, optically-isolated “general-purpose interface” (GPI) ports available
at the REMOTE INTERFACE connector on the rear panel.
•
8600Si PC Remote software is a graphical application that runs under Win-
dows 2000/XP/Vista/7. It communicates with a given 8600Si via TCP/IP over mo-
dem, direct serial, and Ethernet connections. You can configure PC Remote to
switch between many 8600Sis via a convenient organizer that supports giving
