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 OPTIMOD.

The 5500's built-in stereo encoder, AES/EBU digital inputs and outputs, and analog I/O permit hasslefree 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 STL's having 44.1 or 48 kHz sample-rate.

Main Features: 
• Five-band and two-band processing 
• High performance stereo generator 
• Cool running switching power supply 
• Analog and AES3 digital I/O

 

Optimod-FM 5500: Specifications

System

Frequency Response(Bypass Mode)
Follows standard 50 µs or 75 µs pre-emphasis curve ±0.10 dB, 2.0 Hz - 15 kHz. Analog 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.
Total System Distortion
(de-emphasized, 100% modulation) <0.01% THD, 20 Hz - 1 kHz, rising to <0.05% at 15 kHz. <0.02% SMPTE IM Distortion.
Total System L/R Channel Separation
>57 dB, 20 Hz - 15 kHz; 60 dB typical.
Polarity
(Two-Band and Bypass Modes): Absolute polarity maintained. Positive-going signal on input will result in positive-going signal on output.
Processing Samplerate
The 5500 is a "multirate" system, using internal rates from 32 kHz to 512 kHz as appropriate for the processing being performed. Audio clippers operate at 256 kHz (and are anti-aliased), while the composite limiter operates at 512 kHz.

In stand-alone stereo encoder mode, minimum samplerate is 64 kHz.
Processing Resolution
Internal processing has 24 bit (fixed point) or higher resolution.
