orban 8600Si

In the toughest competitive environment ever, a winning strategy includes the OPTIMOD-FM/HD 8600Si.

The Orban OPTIMOD 8600Si features a versatile five-band and two-band processing for both analogue FM transmission and digital media, the 8600 provides the industry’s most consistent sound, track-to-track and source-to-source. This consistency allows you to create a sonic signature for your station with the assurance that your signature will stay locked in, uniquely branding your sound.

  • Orban’s MX limiter technology lowers distortion, improves transient punch, and minimizes pre-emphasis-induced high-frequency loss.
  • Exclusive “Multipath Mitigator” phase corrector minimizes stereo subchannel energy without compromising stereo separation.
  • HD/digital radio/streaming processing is included at no extra cost.
  • Provides a built-in RDS generator with dynamic PS.
  • A dedicated low-delay headphone monitor chain lets you dial in controlled amounts of “FM limiter sound” to match talent preferences.
  • Versatile remote control by responsive PC Remote application, Telnet-style ASCII terminal commands, and SNMP. Supports Ethernet and serial connections.
  • Delivers the inimitable “Optimod Sound,” proven to attract and hold audiences worldwide.
  • User-Friendly Interface
  • Large (quarter-VGA) active-matrix color liquid crystal display (LCD) Makes setup, adjustment and programming of the 8600 easy. Navigation is by a miniature joystick, two dedicated buttons and a large rotary knob. The LCD shows all metering functions of the processing structure in use.
  • Locate joystick Used to navigate through a menu that lets you recall a preset, modify processing (at three levels of expertise), or access the system's setup controls.
  • Absolute Control of Peak Modulation
  • Universal transmitter protection & audio processing for FM broadcast The 8600 provides universal transmitter protection and audio processing for FM broadcast. It can be configured to interface ideally with any commonly found transmission system in the world, analogue or digital.
  • Pre-emphasis limiting The 8600 provides pre-emphasis limiting for the internationally used pre-emphasis curves of 50 µs and 75 µs. Compared to its predecessor, its new clipping/pre-emphasis-control technology preserves 2.5 to 3 dB more frequency energy while significantly reducing audible clipping distortion at all frequencies. This produces a clean, open sound whose subjective brightness more closely matches the original program.
  • Tight peak control at all its outputs The 8600 achieves extremely tight peak control at all its outputs - analogue, AES3 (for both the analogue FM and HD channels) and composite baseband.
  • Stereo encoder integrated with audio processing Eliminates the overshoot problems that waste valuable modulation in traditional external encoders.
  • Two outputs The stereo encoder has two outputs with independent level controls, each capable of driving 75 Ω in parallel with 47,000 pF, (100 ft / 30 m of coaxial cable).
  • Stereo encoder By integrating the stereo encoder with the audio processing, the 8600 eliminates the overshoot problems that waste valuable modulation in traditional external encoders.
  • Bandwidth limiting & overshoot compensation The 8600 prevents aliasing distortion in subsequent stereo encoders or transmission links by providing bandwidth limiting and overshoot compensated 15 kHz low-pass filters ahead of the 8600's audio outputs and stereo encoder.
  • Internal DSP-based stereo encoder The 8600 has an internal, DSP-based stereo encoder (with a patented "half-cosine interpolation" composite limiter operating at 512 kHz sample rate) to generate the pilot tone stereo baseband signal and control its peak level. The composite limiter is unique, "you can only do this in DSP" process that beats composite clippers by preserving stereo imaging while fully protecting the stereo pilot tone, RDS/RBDS and subcarriers.
  • “Multipath Mitigator” Left/Right Phase Skew Correction The phase skew corrector maximizes the quality of a mono mixdown or blends that might occur in a receiver.
  • Built-in RDS/RBDS generator. Loudness and True Peak Control The digital radio and analogue FM processing chains each include an ITU-R BS.1770-3 Loudness Meter and Loudness Controller for use in countries that enforce a BS.1770 loudness limit on digital radio broadcasts. The 8600HD implements "true peak" control in the HD processing chain by oversampling the HD peak limiter's sidechain at 256 kHz. This allows the 8600 to prevent clipping in a playback device's analogue signal path by predicting and controlling the analogue peak level following the playback device's reconstruction filter to an accuracy of better than 0.5 dB. For typical program material, accuracy is 0.2 dB.
  • Flexible Configuration
  • Single Sideband Because of broadcaster interest in this topic, we have implemented an experimental compatible single sideband/vestigial sideband mode in the 8600's stereo encoder. SSB/VSB operation suppresses the upper sideband of the stereo subcarrier above 38,150 Hz, which reduces the occupied bandwidth of the FM-modulated RF signal. In SSB/VBS mode, the subchannel modulator acts as a pure SSB generator for L-R material in the frequency range of 150 Hz to 17 kHz and as a vestigial sideband generator below 150 Hz.
  • Analog & AES3 digital inputs & outputs OPTIMOD-FM/HD 8600 is supplied with analogue and AES3 digital inputs and outputs. The digital input and the two digital outputs are equipped with sample rate converters and can operate at 32 kHz, 44.1 kHz, 48 kHz, 88.1 kHz and 96 kHz sample rates. The pre-emphasis status and output levels are separately adjustable for the analogue and digital outputs. Each output can emit the analogue FM processed signal, the analogue FM processed signal with diversity delay applied, the digital radio processed signal or the low-delay monitor signal.
  • Analog & AES3 digital inputs & outputs A loop-through connection is provided to enable a rating encoder (such as Arbitron®) to be inserted at the output of the AGC (before the analog-FM and HD processing paths split) or between the output of the audio processing and the input to the stereo encoder.
  • Defeatable diversity delay A defeatable diversity delay can delay the FM analogue processing output up to 16.2 seconds. Delay can be trimmed in intervals of one sample of 64 kHz to match the analogue and digital paths in the HD Radio system, eliminating the need to use the delay built into the HD Radio exciter and permitting the 8600's internal stereo encoder and composite limiter to drive the analogue FM exciter. Each output (Analog, Digital 1, Digital 2, Composite(analogue and digital)) can be independently configured to emit the delayed or undelayed signal.
  • AES11 sync input An AES11 sync input allows you to synchronize the output sample rate of either (or both) AES3 outputs to this input. You can also synchronize the outputs to the AES3 digital input or to the 8600's internal clock. The sync source of each AES3 output is independently selectable.
  • Transformerless, balanced 10 k Ω instrumentation-amplifier circuits The analogue inputs are transformerless, balanced 10 kΩ instrumentation-amplifier circuits. The analogue outputs are transformerless balanced and floating (with 50 Ω impedance) to ensure the highest transparency and accurate pulse response.
  • Two independent composite baseband outputs The 8600 has two independent composite baseband outputs with digitally programmable output levels. Robust line drivers enable them to drive 100 feet of RG59 coaxial cable without audible performance degradation.
  • Two subcarrier inputs The 8600's two subcarrier inputs are mixed with the output of the 8600's stereo encoder before application to the composite output connectors. One input can be re-jumpered to provide a 19 kHz pilot reference output. Both inputs have internal level trims to accommodate subcarrier generators with output levels as low as 220 mV.
  • Precise control of the audio bandwidth The 8600 precisely controls the audio bandwidth of its analogue FM processing to 16.5 kHz. This prevents significant overshoots in uncompressed digital links operating at a 44.1 kHz-sample rate or higher and prevents interference to the pilot tone and RDS (or RBDS) subcarrier. The bandwidth of the 8600's digital radio output is adjustable in 1 kHz increments between 15 kHz and 20 kHz.
  • Defeatable multiplex power limiter The 8600 has a defeatable multiplex power limiter that controls the multiplex power to ITU-R BS412 standards. An adjustable threshold allows a station to achieve maximum legal multiplex power even if the downstream transmission system introduces peak overshoots into the 8600-processed signal. Because this limiter closes a feedback loop around the audio processing, it allows the user to adjust the processor's subjective setup controls freely without violating BS412 limits, regardless of program material. The multiplex power limiter acts on all outputs (not just the composite output). In its most common configuration, it reduces clipper drive when it reduces power, simultaneously reducing clipping distortion. However, to accommodate customers who wish to use heavier clipping to achieve a certain sound, the MPX power controller can be configured to reduce gain after the clippers.
  • RFI-suppressed connections 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 8600 is designed and certified to meet all applicable international safety and emissions standards.
  • Adaptability through Multiple Audio Processing Structures
  • Processing structure 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, although all are active simultaneously to permit mute-free switching between them. The 8600 realizes its processing structures as a series of high-speed mathematical computations made by Digital Signal Processing (DSP) chips.
  • Featuring six processing structures The 8600 features six processing structures. Four of these are the same as OPTIMOD-FM/HD 8500: Five-Band (or "Multiband") for a consistent, "processed" sound with 17 ms delay (typical), 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 frequency balance of the original program material. A special Two-Band preset creates a no-compromise "Protect" function that is functionally similar to the "Protect" structures in earlier Orban digital processors.
  • "MX" structures The 8600's two latest "MX" structures (five-band and two-band) are similar to their 8500 counterparts except that they use the 8600's new peak limiting technology to decrease distortion while achieving substantial improvements in transient punch and high-frequency clarity. This advanced technology requires more input-to-output delay than the older structures, so it is impractical for talent to monitor these structures off-air with headphones. The 8600 offers a special low-delay monitor output for this purpose.
  • Phase-linear The 8600's Two-Band processing structures can be made phase-linear to maximize audible transparency.
  • Rides gain The 8600 rides gain over an adjustable range of up to 25 dB, compressing dynamic range and compensating for both operator gain-riding errors and gain inconsistencies in automated systems.
  • Increase density and loudness The 8600 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.
  • Controllable
  • Remote control The 8600 can be remote-controlled by 5 - 12V pulses applied to eight programmable, optically isolated GPI (general-purpose interface) ports.
  • Serial port #1 The 8600 is equipped with a serial port to interface to a WIndows® computer running Orban's PC Remote software. The connection can be either direct or through an external modem.
  • Serial port #2 The 8600 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.
  • Built-in 100 Mbps Ethernet port The 8600 can be connected through its built-in 100 Mbps Ethernet port to a TCP/IP network.
  • SNMP The SNMP (Simple Network Management Protocol) features allow you to monitor the 8600's status and to send Alarm notifications via the 8600's Ethernet connection to your network.
  • Telnet client The 8600 includes a Telnet client that allows presets to be recalled via batch files using the free PuTTY and Plink applications. The commands are simple ASCII strings, facilitating an interface to automation systems that can emit such strings through an Ethernet or RS232 serial connection.
  • PC Remote control software 8600 PC Remote software is a graphical application that runs under Windows 2000, XP, Vista, 7 and 8. It communicates with a given 8600 via TCP/IP over modem, direct serial and Ethernet connections. You can configure PC Remote to switch between many 8600s via a convenient organizer that supports giving any 8600 an alias name and grouping multiple 8600s into folders. Clicking an 8600's icon causes PC Remote to connect to that 8600 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 8600 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.).
  • Bypass Test Mode A Bypass Test Mode can be invoked locally, by remote control (from the 8600’s GPI port, its PC Remote application, or ASCII API), or by automation to permit broadcast system test and alignment or “proof of performance” tests.
  • Built-in line-up tone generator The 8600 contains a built-in line-up tone generator, facilitating quick and accurate level setting in any system.
  • Versatile real-time clock The 8600 contains a versatile real-time clock, which allows automation of various events (including recalling presets) at pre-programmed times. To maintain accuracy, this clock can be automatically synchronized via the Internet to a reference time source.
