Overview
Three Processors in One:
A no-compromise processing chain for digital
transmission and media
A studio AGC (with peak limiting for STL
protection)
A talent headphone processor.
The Orban 6300 is a high-quality, multipurpose stereo audio
processor for digital radio, digital television, netcasts, STL
protection, satellite uplink protection, and digital mastering. With
20 kHz audio bandwidth, the 6300 succeeds Orban's popular OPTIMOD-DAB
6200 audio processor but offers improved processing algorithms and
more flexibility.
Orban's new PreCode™ technology manipulates several
aspects of the audio to minimize artifacts caused by low bitrate
codecs, ensuring consistent loudness and texture from one source to
the next. There are several factory presets tuned specifically for
low bitrate codecs.
In sound-for-picture applications, the 6300's built-in CBS
Loudness Controller™ tames source-to-source loudness
variations, ensuring consistency and maximizing audience
satisfaction.
Because of its versatile signal routing, the 6300 can be used as
a combined studio AGC, digital radio/digital television/netcast
processor, and low-delay talent headphone processor. Any of its
three outputs (stereo analog x1; AES2 digital x2) can emit any of
the following signals:
- Stereo enhancement, equalization,
and AGC without look-ahead peak limiting
- Stereo enhancement, equalization,
and AGC with peak limiting
- Stereo enhancement, equalization,
and multiband processing (2-band or 5-band, including AGC)
without peak limiting
- Stereo enhancement, equalization,
and multiband processing (2-band or 5-band, including AGC) with
peak limiting
In a typical application:
- The 6300 substitutes for the AGC in
an Optimod at the transmitter and provides protection limiting
for the STL. Digital output #1 emits the peak-limited output of
the AGC to drive the STL. The AGC is turned off in the
transmitter-side Optimod.
The 6300's AGC uses the same dual-band,
window-gated, matrix technology as the AGCs in Orban's 2300,
5300, 8300, 8382, 8400, 8500, 9300, and 9400 Optimods. It can
therefore accurately substitute for the AGCs in these devices
and can help maintain an all-digital signal path throughout the
facility. Because the 6300's AGC is more advanced than the AGCs
in Orban's 2200, 8200, and 9200 Optimods, the 6300 can upgrade
the performance of these older products when substituted their
AGCs.
Moreover, because the 6300 supports presets that be recalled by
remote control, it can be automatically synchronized to the
presets on-air at a transmitter-side Optimod when presets are
dayparted.
The 6300's multiband processing is based on the technology used
in Optimod-FM 8500's digital radio processing path and will
sound similar. To help you match the sound of an 8400 or 8500,
the 6300 provides presets with the same names as those in
Optimod-8400 and 8500. If you are using a factory preset at a
transmitter-side 8400 or 8500, you can recall a preset with the
same name in the 6300 to ensure that the sound stays the same as
it would if you were using an 8400 or 8500 with its internal AGC.
- Digital output #2 emits a
peak-limited, multiband-processed signal to drive a netcast
encoder (like Orban's Opticodec-PC), a digital radio
transmitter, or a digital television transmitter.
- The analog output emits a low-delay
(~5 ms) multiband-processed signal with no peak limiting to
drive talent headphones at the studio. This is particularly
useful in HD Radio™ facilities, where off-air
headphone monitoring is impossible due to delay.
The 6300's two independent stereo look-ahead limiters can be
switched to operate either "flat" or on a 50µs or 75µs
pre-emphasis curve to protect a pre-emphasized path like a typical
analog microwave STL.
Because the look-ahead peak limiting
technology used in the 6300 performs optimally with "flat"
transmission channels (like almost all digital channels), the
6300 cannot provide loudness processing for pre-emphasized radio
channels. Use one of Orban's Optimod-FM processors for this
application. For analog television with FM aural carrier(s), use
Optimod-TV 8382.
