Controllable - Orban OPTIMOD 6300 Operating Manual

OPTIMOD 6300 DIGITAL

A special 2-band preset creates a no-compromise "Protect" function that is func-
tionally similar to the "Protect" structures in earlier Orban digital processors.
The 5-band and the 2-band structures can be switched via a mute-free crossfade.

The 6300 includes third-generation CBS Loudness Controllers™ for DTV appli-
cations. Separate loudness controllers are available for the two channels
in dual-mono mode. The CBS algorithm has proven its effectiveness by
processing millions of hours of on-air programming since the early 1980s. It
smoothly limits subjectively perceived loudness to a broadcaster-set threshold,
preventing audience irritation. The controller measures subjective loudness
(as perceived by an average listener) and then closes a feedback loop to limit
loudness to a preset level. It effectively controls loud commercials, which are the
primary irritant in sound-for-picture applications. Third generation improve-
ments reduce annoyance more than simple loudness control alone, doing
so without audible gain pumping. Attack time is adjustable to trade off
short-term loudness control against transient punch.

The 6300's AGC rides gain over an adjustable range of up to 25dB, compressing
dynamic range and compensating for both operator gain-riding errors and gain
inconsistencies in automated systems. The AGC output is available to drive STLs,
so the 6300 can be used as a studio AGC.

The 6300's processing structures are all phase-linear to maximize audible trans-
parency.

The 6300's equalizers and crossovers use 48-bit arithmetic to ensure mastering-
quality noise and distortion performance.

Controllable


The 6300 can be remote-controlled by 5-12V pulses applied to eight pro-
grammable, optically isolated "general-purpose interface" (GPI) ports.

6300 PC Remote software is a graphical application that runs under Windows
2000 and XP. It communicates with a given 6300 via TCP/IP over modem, direct
serial, and Ethernet connections. You can configure PC Remote to switch be-
tween many 6300s via a convenient organizer that supports giving any 6300 an
alias and supports grouping multiple 6300s into folders. Clicking a 6300's icon
causes PC Remote to connect to that 6300 through an Ethernet network or initi-
ates a Windows Dial-Up or Direct Cable Connection if appropriate. The PC Re-
mote software allows the user to access all 6300 features (including advanced
controls not available from the 6300's front panel) and allows the user to archive
and restore presets, automation lists, and system setups (containing I/O levels,
digital word lengths, GPI functional assignments, etc.).
