OPTIMOD-FM 8200 with the latest V3.0 software, is a powerful and flexible audio processor for FM radio broadcasting. The 8200 proprietary processing structures let you forge a signal that is loud, bright, clean and more attractive to listeners. You can use the included factory presets or customize parameters to create a unique signature sound. Benefits of digital processing and control include elimination of analog component drift, automatic preset switching for day-parting, and remote control via PC software and modem. All-digital processing for the ultimate in sound quality and operating flexibility. Three processing structures: Multi-Band, Two-Band, and transparent Protection Limiter. Processing algorithms developed through thousands of hours of listening tests. 24 program presets with over 150 field-tested settings. Processing parameters may be adjusted and stored in memory. ROM-based, digital Hadamard Baseband Encoder[R] for drift-free composite baseband signal with extremely low noise and distortion. Modular design allows expansion of DSP power. Software upgrades supplied on plug-in modules. Computer interface/software for remote operation using PC and modem. New Version 3.0 Software. It is impossible to characterize the listening quality of even the simplest limiter or compressor on the basis of specifications, because such specifications cannot adequately describe the crucial dynamic processes that occur under program conditions. Therefore, the only way to meaningfully evaluate the sound of an audio processor 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. Some of the specifications are for features that are optional or may not yet be available at the time you place your order. Consult the current price list for details. PERFORMANCE Specifications for measurements from analog left/right input to stereo composite output and to analog left/right output. Frequency Response (all structures, measured below gain reduction and clipping thresholds, high-pass filter off): Follows standard 50 microseconds or 75 microseconds pre-emphasis curve ±0.20dB, 5Hz-15kHz. Analog left/right output and 8200D/SRC digital output can be user configured for flat or pre-emphasized output. 8200D/32 output follows selected pre-emphasis curve. 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. It is primarily governed by the dynamic range of the A/D Converter, which has a specified overload-to-noise ratio of 97dB. The dynamic range of the digital signal processing is 144dB. Total System Distortion (de-emphasized,100% modulation): <0.01% THD, 20Hz-1kHz, rising to <0.05% at 15kHz. <0.02% SMPTE IM Distortion. Total System Separation: >65dB, 20Hz-15kHz; 70dB typical. Polarity (PROTECTION, TWO-BAND PURIST, or BYPASS structure): Absolute polarity maintained. Positive-going signal on input will result in positive-going signal on output. INSTALLATION ANALOG AUDIO INPUT Configuration: Left and right. Impedance: 600 ohm or 10k ohm load impedance, electronically balanced, jumper-selectable. Common mode rejection: >70dB, 50-60Hz. >45dB, 60Hz-15kHz. Sensitivity: -40dBu to +20dBu to produce 10dB gain reduction at 1kHz. Maximum input level: +27dBu. Connectors: XLR-type, female, EMI-suppressed. Pin 1 Chassis, Pins 2 and 3 electronically balanced, floating and symmetrical. ANALOG AUDIO OUTPUT Configuration: Left and right. Flat or pre-emphasized. Source Impedance: 30 ohm, ±5%, electronically balanced and floating. Load Impedance: 600 ohm or greater, balanced or unbalanced. Termination not required. Maximum Output Level: +23.7dBu into 600 ohm or greater balanced load. Connectors: XLR-type, male, EMI-suppressed. Pin 1 Chassis, Pins 2 and 3 electronically balanced, floating and symmetrical. DIGITAL I/O Configuration: Requires 8200D/32 or 8200D/SRC I/O card. Input Configuration: Two-channel AES/EBU standard. Output Configuration: D/32: Two-channel AES/EBU standard, pre-emphasized to the same pre-emphasis as selected for the processing.
