Optimod-FM 5500: Overview
Competitive OPTIMOD sound in a compact package at the most affordable price ever.
OPTIMOD-FM 5500 puts coveted five-band and two-band OPTIMOD processing into a single rack unit package and brings it to you at the most affordable price ever. The 5500 replaces OPTIMOD-FM 5300 and 2300, offering the functionality of both processors in a new, cool-running package.
Quality sound is what 5500 is all about - sound that attracts audiences by providing a polished, professional presentation regardless of format and source material. Exceptional versatility allows you to adjust the processor's audio texture to brand your audio, knowing that the resulting signature sound will remain consistent, cut-to-cut and source-to-source. Branding builds businesses and no other processors have the consistency to brand your sound like OPTIMODs.
The 5500 can also be used as a superb stand-alone stereo encoder with latency as low as 2 ms and full overshoot limiting in both the left/right and composite baseband domains. When used in this mode, the 5500 must be driven (usually via an STL) by a full-featured FM audio processor (like Orban's 8600) that incorporates preemphasis-aware HF limiting and peak control. In both modes, the 5500's stereo encoder helps deliver a transmitted signal that's always immaculately clean and perfectly peak limited, with full spectral protection of subcarriers and RDS/RBDS regardless of the amount of composite limiting.
The 5500 is the ideal choice for network broadcasters who process with Orban's flagship OPTIMOD-FM 8600 at the network origination point and who need a processor at every transmitter to eliminate STL overshoots (using the 5500's stand-alone stereo encoder mode) and/or to process local insertions while also eliminating network STL overshoots (using the 5500's audio processor / stereo encoder mode). Moreover, the 5500's two modes make it easy for large government and network broadcasters to manage its inventory of spares because any 5500 can be used as a stereo encoder with or without audio processing.
Available in both modes, the built-in, defeatable ITU BS412 multiplex power controller allows the 5500's output to meet even the most stringent European government regulations.
New in 5500 is a 10 MHz frequency reference input allows the stereo pilot tone frequency to be locked to GPS or another high-accuracy frequency standard. This improves the performance of single-frequency networks in areas where coverage of the transmitters overlaps. Also new is a cool-running, energy-efficient switching power supply and use of the latest dual-core DSP chip technology from Freescale Semiconductor.
With the 5500, your signature sound is just a preset away. An easy, one-knob Less/More adjustment allows you to customize any factory preset, trading cleanliness against processing artifacts according to the requirements of your market and competitive environment. Full Control gives you the versatility to customize your audio further. And, if you're a hard-core processing expert, you can explore Advanced Control to tweak presets at the same level as Orban's factory programmers. This versatility makes the 5500 a superb choice for any format. Its five-band processing is ideal for any pop music format (even the most competitive and aggressive CHR), while phase-linear two-band processing yields ultra-transparent sound for classical, classic jazz, and fine arts formats. Regardless of your choice, 5500's optimized technology ensures unusually high average modulation and coverage for a given level of subjective quality. Unlike many lesser processors, the 5500 handles speech particularly well - it's always clean, even when you process for loudness.
Versatility doesn't stop with sound. The 5500's built-in stereo encoder, AES/EBU digital inputs and outputs, and analogue I/O permit hassle-free interfacing to any broadcast plant, whether the 5500 is located at the studio or the transmitter. Tight band limiting to 15 kHz means you can use any uncompressed digital STL to pass 5500-processed audio from studio to transmitter without compromising on-air loudness - there's no need to use STLs having 44.1 or 48 kHz samplerates. If you want to locate the 5500 away from the studio, you'll be pleased by its three separate remote control ports - GPI contact closures, RS232 serial, and built-in Ethernet for TCP/IP networks. The serial and Ethernet ports are supported by the supplied 5500 PC Remote Control application. This Windows® 2000/XP/Vista/7 application allows you to do even more with the 5500 than you can do through its front panel, making remote control a pleasure.
Built-in clock-based automation lets you automatically daypart the processing. You can control many other 5500 operating parameters too; the 5500's feature set fully exploits the processor's DSP and computer-based control architecture. To ensure absolute accuracy, you can automatically synchronize the clock to an Internet timeserver.
If you're concerned about latency because you need to feed live talent headphones off air, be assured that the 5500's ultra-low-latency (5 ms delay) processing will keep the most finicky talent happy. Or use optimum latency (15 ms delay) processing for the most competitive sound with delay that's still low enough to satisfy most any talent.
Features
User-Friendly Interface
LCD and full-time LED meters
An LCD and full-time LED meters make setup, adjustment and programming of OPTIMOD-FM easy - you can always see the metering while you are 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.
Universal transmitter protection & audio processing for FM broadcast
The 5500 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.
Pre-emphasis limiting for the two standard pre-emphasis curves of 50 µs & 75 µs
The 5500 provides pre-emphasis limiting for the two standard pre-emphasis curves of 50 µs and 75 µs. Its pre-emphasis control is seldom audibly apparent, producing a clean, open sound with subjective brightness matching the original program.
Tight peak control at all its outputs
The 5500 achieves extremely tight peak control at all its outputs — analogue left/right, AES3 left/right, and composite baseband.
Stereo encoder integrated with audio processing
By integrating the stereo encoder with the audio processing, the 5500 eliminates the overshoot problems that waste valuable modulation in traditional external encoders.
Stereo encoder has two outputs with independent level controls.
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).
Bandwidth-limiting & overshoot compensation
The 5500 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 5500's audio outputs and stereo encoder.
Anti-aliased clippers
Anti-aliased clippers running at 256 kHz samplerate prevent any trace of "digital clipper" sound.
Flexible Configuration
Analogue & AES3 digital inputs & outputs
The 5500 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 5500 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 5500 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 5500 eliminates the overshoot problems that waste valuable modulation in traditional external encoders.
Bandwidth limiting & overshoot compensation
The 5500 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 5500's audio outputs and stereo encoder.
Internal DSP-based stereo encoder
The 5500 has an internal, DSP-based stereo encoder (with a patented "half-cosine interpolation" composite limiter operating at 512 kHz samplerate) to generate the pilot tone stereo baseband signal and control its peak level. The composite limiter is a 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.
Flexible Configuration
Analogue & AES3 digital inputs & outputs
The 5500 includes analogueue and AES3 digital inputs and outputs. Both digital input and digital output are equipped with sample-rate converters and can operate at 32 kHz, 44.1 kHz, 48, 88.2 and 96 kHz samplerates. The pre-emphasis status and output levels are separately adjustable for the analogueue and digital outputs.
Internal, DSP-based stereo encoder (with a patented "half-cosine interpolation" composite limiter operating at 512 kHz samplerate)
The 5500 has an internal, DSP-based stereo encoder (with a patented "half-cosine interpolation" composite limiter operating at 512 kHz samplerate) to generate the pilot tone stereo baseband signal and control its peak level. The composite limiter is a 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.
Transformerless, balanced 10 kΩ instrumentation-amplifier circuits
The analogueue inputs are transformerless, balanced 10 kΩ instrumentation-amplifier circuits, and the analogueue outputs are transformerless balanced, and floating (with 50 Ω impedance) to ensure highest transparency and accurate pulse response.
Two independent composite baseband outputs with digitally programmable output levels
The 5500 has two independent composite baseband outputs with digitally programmable output levels. Robust line drivers enable them to drive 100 feet of RG-59 coaxial cable without audible performance degradation.
Two subcarrier inputs
The 5500 has two subcarrier inputs that are mixed with the output of OPTIMOD-FM's stereo encoder before application to the composite output connectors. One input can be re-jumpered to provide a 19 kHz pilot reference output. Each input has an internal level trim to accommodate subcarrier generators with output levels as low as 220 mV.
Precise control of audio bandwidth to 15 kHz
The 5500 precisely controls the audio bandwidth to 15 kHz. This prevents overshoots in uncompressed digital links operating at a 32 kHz samplerate and prevents interference to the pilot tone and RDS (or RBDS) subcarrier.
Defeatable, extremely accurate multiplex power limiter
The 5500 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 5500-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). It reduces clipper drive when it reduces power, simultaneously reducing clipping distortion. To prevent audible gain pumping, a user-adjustable gain offset control allows the user to minimize the amount of gain control that the controller performs.
10 MHz clock / wordclock reference input
The 5500 has a 10 MHz clock / wordclock reference input, which can be used to lock the stereo pilot tone to a high precision external reference like a GPS-based frequency standard.
This facilitates using the 5500 in single-frequency network applications.
Rigorously RFI-suppressed input, output & power connections
All input, output and power connections are rigorously RFI-suppressed to Orban's traditional exacting standards, ensuring trouble-free installation.
Certified
The 5500 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-FM realizes its processing structures as a series of high-speed mathematical computations made by Digital Signal Processing (DSP) chips.
Three processing structures
The 5500 features three processing structures: Optimum Five-Band (or "Multiband"; 15 ms delay) for a consistent, "processed" sound, free from undesirable side effects, Ultra-Low-Latency Five-Band (5 ms delay) for environments where talent monitors live off-air and they object to the delay of Optimum Five-Band and Two-Band 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. The Optimum Five-Band and the Two-Band structures can be switched via a mute-free crossfade; switching to or from the Ultra-Low Latency Five-Band structure causes the audio to mute momentarily.
Rides gain over an adjustable range of up to 25 dB
The 5500 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.
Multiband compression, limiting & clipping
The 5500 can increase the density and loudness of the program material by multiband compression, limiting, and clipping. This improves the consistency of the station's sound and increasing loudness and definition remarkably, without producing unpleasant side effects.
Two-Band processing structure is phase-linear
The 5500's Two-Band processing structure is phase-linear to maximize audible transparency.
5500 PC Remote application
The 5500 can import and run any 8300, 8400, 8500 or 8600 "LL" (Low-Latency) preset via the 5500 PC Remote application. This means that you can use an 8300, 8400, 8500 or 8600 to develop presets for 5500, provided you do not use features in the other processors not supported by the 5500. (If you try to import a preset that uses features unsupported by 5500, the 5500 will interpret that preset as best it can by using its available processing features.)
Controllable
Eight programmable, optically isolated "general-purpose-interface" (GPI) ports
The 5500 can be remote-controlled by 5 - 12V pulses applied to eight programmable, optically isolated "general-purpose interface" (GPI) ports.
5500 PC Remote software
5500 PC Remote software is a graphical application that runs under Windows 2000/XP/Vista/7. It communicates with a given 5500 via TCP/IP over modem, direct serial and Ethernet connections. You can configure PC Remote to switch between many 5500s via a convenient organizer that supports giving any 5500 an alias and grouping multiple 5500s into folders. Clicking a 5500's icon causes PC Remote to connect to that 5500 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 5500 features (including advanced controls not available from the 5500'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.).
Versatile real-time clock
OPTIMOD-FM contains a versatile real-time clock, which allows automation of various events (including recalling presets) at pre-programmed times. The clock can be synchronized automatically to an Internet timeserver.
Bypass Test Mode
A Bypass Test Mode can be invoked locally, by remote control (from either the 5500's GPI port or the 5500 PC Remote application) or by automation to permit broadcast system test and alignment or "proof of performance" tests.
Built-in line-up tone generator
OPTIMOD-FM contains a built-in line-up tone generator, facilitating quick and accurate level setting in any system.
Upgrateable Software
OPTIMOD-FM's software can be upgraded by running Orban-supplied downloadable upgrade software on a PC. The upgrade can occur remotely through the 5500's Ethernet port or serial port (connected to an external modem) or locally (by connecting a Windows® computer to the 5500's serial port through the supplied null modem cable).
Stand-Alone Stereo Encoder Operation
Samplerate and multiples thereof
The samplerate is 64 kHz and multiples thereof, up to 512 kHz. The internal audio bandwidth is high enough to prevent overshoot caused by spectral truncation of the left/right input signals that are band-limited to 18 kHz or lower.
Low-pass filtering
15, 16 or 17 kHz linear-phase low-pass filtering can be applied to the input signal. To minimize input/output delay, this filter can be bypassed, which is appropriate if the input signal is correctly band-limited by the audio processor driving the 5500.
Left/right domain overshoot limiter
A left/right domain overshoot limiter is available. This uses the same technology as Orban's 8218 stand-alone stereo encoder, combining look-ahead and band-limited clipping techniques to control STL-induced overshoots while minimizing artifacts.
Dual-mode composite limiter
A dual-mode composite limiter is available. It can operate in either "Half-Cosine Interpolation" mode or conventional hard clipper mode. The "Half-Cosine" mode provides better separation and preservation of stereo imaging, while the "Hard" mode provides brighter sound because it creates waveforms that are closer to square waves. Both modes provide excellent spectral protection of the pilot tone and subcarrier regions. To ensure accurate peak control, the limiter operates at 512 kHz samplerate.
J.17 de-emphasis
The 5500 can apply J.17 de-emphasis to the input signal.
ITU412 multiplex power controller
A high-accuracy ITU412 multiplex power controller is available, with user control over the multiplex power threshold.
This allows you to compensate for overshoots in the signal path upstream from the 5500, preventing excessive reduction of the multiplex power.
Flat or pre-emphasized input signal
The input signal can be flat or pre-emphasized to 50 µs or 75 µs.
Silence alarm and digital audio fault tally outputs
Silence alarm and digital audio fault tally outputs are available.
Inputs and outputs
All normal 5500 inputs and outputs are available, including analogue and digital inputs, two composite outputs with independent level controls and two subcarrier inputs (one of which can be repurposed to emit a 19 kHz pilot reference output for RDS/RBDS generators).
Specifications
It is impossible to characterize the listening quality of even the simplest limiter or compressor based on specifications because such specifications cannot adequately describe the crucial dynamic processes that occur under program conditions. Therefore, the only way to evaluate the sound of an audio processor meaningfully is by subjective listening tests.
Certain specifications are presented here to assure the engineer that they are reasonable, to help plan the installation, and make certain comparisons with other processing equipment.
Specifications apply for measurements from analogue left/right input to stereo composite output and to FM analogue left/right output.
System
Frequency Response(Bypass Mode)
Follows standard 50 µs or 75 µs pre-emphasis curve ±0.10 dB, 2.0 Hz - 15 kHz. analogue left/right output and digital output can be user-configured for flat or pre-emphasized output.
Noise
Output noise floor will depend upon how much gain the processor is set for (Limit Drive, AGC Drive, Two-Band Drive, and/or Multi-Band Drive), gating level, equalization, noise reduction, etc. The dynamic range of the A/D Converter, which has a specified overload-to-noise ratio of 110 dB, primarily governs it. The dynamic range of the digital signal processing is 144 dB.
