Features
User-Friendly Interface
- LCD and full-time LED meters
An LCD and full-time LED meters make setup, adjustment and programming of the 6586 easy — you can always see the metering while you're adjusting the processor. Navigation is by dedicated buttons, soft buttons (whose functions are context-sensitive), and a large rotary knob. The LEDs show all metering functions of the processing structure (Two-Band or Five-Band) in use.
Absolute Control of Peak Modulation
- Pre-emphasis limiting for
the two standard pre-emphasis
curves of 50 µs & 75 µs
While primarily oriented toward “flat” media, the 6585’s stereo processors can also provide pre-emphasis limiting for the two standard pre-emphasis curves of 50 μs and 75 μs. This allows the 6585 to protect pre-emphasized microwave links, satellite uplinks and similar channels where protection limiting or light processing is required. It can also drive an analog television transmitter.
Note that the 6585’s stereo processing cannot provide simultaneous, independent audio processing for flat and pre-emphasized channels. Even though one output may be pre-emphasized while other is flat, the only difference between the outputs is that the “flat” output has de-emphasis applied to it after the processing while the pre-emphasized output does not.
Flexible Configuration
- Up to four processors in one
A gain-coupled multichannel processor for up to 7.1 channels, or four independent stereo processors (each of whose performance is equivalent to an OPTIMOD 6300) that can be used for many tasks such as processing the audio for a second language or for processing up to four ATSC subchannels. - Processing in dual-mono mode
The 6585's stereo processing offers a dual-mono mode that allows two entirely separate mono programs to be processed, facilitating multiple-language operation.
In this mode, both processing channels operate using the same processing parameters (like release time); you cannot adjust the two channels to provide different processing textures. - Video delay by up to 11 frames
The I/O interface includes an HD-SDI input and output [(per SMPTE 259M); 1.5 Gbit/s HD-SDI (per SMPTE 292M; up to 720p and 1080i) and 3.0 Gbit/s single-wire HD-SDI (per SMPTE 424M; 1080p)], plus three AES3id inputs and three AES3 id outputs, which can be used as a loop-through for Orban's Penteo® 2.0 → 5.1 upmixer or to provide I/O for up to three channels of stereo processing. - Input and output interfaces
The 6585 can delay the video by up to 11 frames to match the delay of the 6585's loudness processing (typically 20 ms), optional Penteo™ upmixer. - Hard-wire safety bypass
Relays provide hard-wire safety bypass from the SDI input to the SDI output and from corresponding AES3id inputs to outputs. - Use 6585 as an AES splitter
Via the internal output routing switcher, a given output signal can be applied to more than one hardware output. This allows using the 6585 as an AES splitter. - Highly configurable via
routing switchers
OPTIMOD 6585’s inputs and outputs are highly configurable via remotecontrollable internal routing switchers. Additionally, the outputs of the multichannel and stereo processing chains can be independently configured to emit the output of the AGC or the output of the multiband compressor/limiter, all configurable to use or bypass look-ahead limiting. - Highest transparency and
accurate pulse response
A stereo analog monitor output appears on XLR connectors on the rear panel. It can be configured to emit any 6585 output signal, including a downmix of the multichannel audio. The analog outputs are transformerless, balanced and floating (with 50 Ω impedance) to ensure highest transparency and accurate pulse response. They can be used to drive a transmitter, although their normal function is monitoring. - Dolby Digital metadata
accepted and emited
Two RS485 serial ports allow the 6585 to accept and emit Dolby Digital metadata. Metadata can also be de-embedded and re-embedded in the HD-SDI VANC area [per SMPTE 2020-2-2008 (Method-A) or SMPTE 2020-3-2008 (Method-B)] and, if the Dolby-E modules are installed, de-embedded from and re-embedded into Dolby-E data that is conveyed either through from the HD-SDI connection or the AES3id connections. - Video sync via BNC connector
A BNC connector can accept video sync per SMPTE 274M and SMPTE 296M, which can be used as a reference for the output audio sample rate and to correctly align Dolby-E frames with video per Dolby’s requirements. The signal applied to the SDI input can also be used as a sync reference. - Audio sync input
An audio sync input is configurable to accept AES11id or wordclock sync. You can synchronize the output sample rate of all AES3id outputs to this input. You can also synchronize the outputs to the AES3 digital input #1, the SDI input, the Video Sync input or the 6585’s internal crystal-controlled clock. The sync source of each AES3 output is independently selectable. - Dual power supplies
Dual power supplies with independent AC line inputs provide redundant operation. - RFI-suppressed
All input, output and power connections are rigorously RFI-suppressed to Orban’s traditional exacting standards, ensuring trouble-free installation. - International safety and emissions standards
The 6585 is designed and certified to meet all applicable international safety and emissions standards.
Adaptability through Multiple Audio Processing Structures
- Complete audio processing system
A processing structure is a program that operates as a complete audio processing system. Only one processing structure can be on-air at a time. OPTIMOD 6585 realizes its processing structures as a series of high-speed mathematical computations made by Digital Signal Processing (DSP) chips. - Two processing structures
The 6585 features two processing structures: Five-Band for a spectrally consistent sound and Two-Band for a more transparent sound that preserves the frequency balance of the original program material. - “Protect” function
A special Two-Band preset creates a no-compromise “Protect” function that is functionally similar to the “Protect”structures in earlier Orban digital processors. - Mute-free crossfade
The Five-Band and the Two-Band structures can be switched via a mute-free crossfade. - Pass-Through via remote
control or clock-based
automation
Audio processing can be smoothly activated and defeated on-air, allowing programs that can benefit from full dynamic range to pass through the 6585 without dynamics compression. This pass-through mode, which passes both audio and metadata, can be activated and defeated via clock-based automation, from the 6585's front panel, from 6585's PC Remote software, from 6585's programmable GPI inputs, or from 6585's Ethernet or RS232 serial API. - Rides gain over an adjustable range of up to 25 dB
The 6585'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 6585 can be used as a studio AGC. - Phase-linear processing structures
The 6585's processing structures are all phase-linear to maximize audible transparency. - 48-bit equalizers and crossovers
The 6585's equalizers and crossovers use 48-bit arithmetic to ensure mastering-quality noise and distortion performance. - CBS Loudness Controllers™
The 6585 includes third-generation CBS Loudness Controllers™ for DTV applications. Loudness controllers are available in the surround and 2.0 processing modes and work with the both Two-Band and Five-Band structures. The third-generation improvements reduce annoyance more than simple loudness control alone, doing so without audible gain pumping. Attack time is fast enough to prevent audible loudness overshoots, so the control is smooth and unobtrusive. Material processed by the CBS Loudness Controller has been shown to be well controlled when measured with a long-term loudness meter using the ITU-R BS.1770-2 standard. - Orban's PreCode™ technology
Orban's 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. It is particularly useful when processing for netcasts or mastering for any low bitrate channel. PreCode™ includes special audio band detection algorithms that are energy and spectrum aware. This can improve codec performance on some codecs by reducing audio processing induced codec artifacts, even with program material that has been preprocessed or mastered by other processing than OPTIMOD. There are several factory presets tuned specifically for low bitrate codecs.
Controllable
- Eight programmable, optically
isolated “general-purpose
interface” (GPI) ports
The 6585 can be remote-controlled by 5-12V pulses applied to eight programmable, optically isolated “general-purpose interface”(GPI) ports. These can be programmed to recall factory and user presets, factory and user Setups, and to activate test modes. - 6585 PC Remote software
6585 PC Remote software is a smooth, responsive graphical application that runs under Windows XP and Vista. It communicates with a given 6585 via TCP/IP over modem, direct serial, and Ethernet connections. You can configure PC Remote to switch between many 6585s via a convenient organizer that supports giving any 6585 an alias and supports grouping multiple 6585s into folders. Clicking an 6585's icon causes PC Remote to connect to that 6585 through an Ethernet network or initiates a Windows Dial-Up or Direct Cable Connection if appropriate. The PC Remote software allows the user to access all 6585 features 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.). - Remote administration over TCP/IP
An API provides remote administration over TCP/IP via the RS232 serial or Ethernet ports. The 6585 hosts a TCP /IP terminal server to allow external control of the 6585 from either a Telnet/SSH client or a custom third party application. All commands are simple text strings. You can recall presets, operate the input and output routing switchers and more. Password security is provided. - Versatile real-time clock
The 6585 contains a versatile real-time clock, which allows automation of various events (including recalling presets) at pre-programmed times. To ensure accuracy, the clock can be synchronized to an Internet timeserver. - Silence alarm and tally outputs
Silence alarm and digital audio fault tally outputs are available. - Bypass Test Mode
A Bypass Test Mode can be invoked locally, by remote control (from either the 6585's GPI port or the 6585 PC Remote application), or by automation to permit broadcast system test and alignment or “proof of performance” tests. - Built-in line-up tone generator
The 6585 contains a built-in line-up tone generator, facilitating quick and accurate level setting in any system. - Software Upgrade
The 6585's firmware can be upgraded from PC Remote software. The upgrade can occur remotely through the 6585's Ethernet port or serial port (connected to an external modem), or locally (by connecting a Windows® computer to the 6585's serial port through the supplied null modem cable or to the 6585's Ethernet port via a crossover Ethernet cable).
