Orban 5950 FM/HD Audio Processor

The Orban OPTIMOD 5950 Audio Processor is part of Orban’s new generation of audio processors. At just 1 rack unit (1RU) high, it offers a powerful set of features, including Orban’s innovative MX peak limiter technology. Equipped with a new high-resolution touch-sensitive display controllable via any HTML5 web browser, the 5950 combines user-friendly operation with high-quality OPTIMOD audio processing for FM and DAB+/HD radio broadcasts.

Main features:

The Orban OPTIMOD 5950 audio processor and Orban 8700i enhancement includes several of the brand’s proprietary technologies. The MX peak limiter reduces distortion, increases the impact of transients and offers more high-frequency energy. The multipath mitigator/phase corrector prevents loss of high frequencies during mono listening, including the mixing of weak signals in car radios. The sub-harmonic synthesizer generates powerful bass. The OPTIMOD 5950 simultaneously processes a stereo program for FM, DAB+/HD Radio and Streaming. The settings can be coupled to make the transition between analog and HD1 as smooth as possible in HD Radio. Alternatively, FM and digital processing can be adjusted independently. This is useful when digital processing feeds a channel that doesn’t require mixing, such as an internet stream.

Six Processing Structures: Five Bands, Five Low Latency Bands, Five Ultra Low Latency Bands, Two Bands, Five MX Bands and Two MX Bands. Window-controlled AGC: The intelligent two-band AGC controls levels subtly and unobtrusively. RDS/RBDS: The integrated generator supports dynamic PS scrolling and IP access. Audience Measurement: Two internal Nielsen or Kantar encoders are optionally available, allowing FM and DAB+/HD Radio signals to be scored independently. Streaming Monitoring Output: Processed FM or DAB+/HD Radio signals can be monitored remotely via IP, allowing processor adjustment in locations where a clean off-air signal is not available. μMPX Interface: The optional μMPX Interface allows DMPX to be transmitted over IP.

Internal Storage for Audio Backup: A 2 GB Flash Memory provides two hours of linear audio or twelve hours of audio encoded in AAC, MP3 or OPUS. Internet Streaming Decoder: This feature can be used as a backup audio source received via Audio over IP. Diversity Delay: An adjustable delay can be inserted into the FM and/or digital path to ensure time alignment of the FM and HD Radio/DAB+ radio signals in the receiver. “Real Peak” Limiter: The “real peak” limiter in the digital processing path anticipates and controls peak levels after D/A conversion, a feature now required by many broadcasters. ITU BS.412 Multiplexing Power Control: For countries that require multiplexing power to be limited to a specified value, this feature can be activated to ensure compliance while smoothly and reliably controlling the power of the MPX. ITU-R BS.1770-4 Loudness Control: Facilitates compliance with modern target loudness recommendations, such as EBU R 128. Silence Detection: A programmable silence detector is available for the analog, digital and AoIP inputs. It can generate alarms and enable automatic switching to a backup input or backup audio storage. Dual Power Supplies: The OPTIMOD 5950 is equipped with dual monitored power supplies to ensure 24/7 operation. Safety Bypass Relays: The analog, digital AES3 and composite audio inputs and outputs have deactivatable safety bypass relays that come into operation in the event of hardware or power failures. Audio inputs: 2 x analog 2 x digital AES3 2 x Ethernet to AoIP (dual-redundant) Audio outputs: 2 x analog 2 x analog MPX/composite 2 x digital AES3 or 1 x digital AES3 and 1 x DMPX (configurable) 2 x Ethernet to AoIP (dual-redundant) 1 x headphone output (for monitoring) Optional 1 x μMPX (DMPX via IP) SCA inputs: 2 x Synchronization: 10 MHz clock input AES11 synchronization input 19 kHz reference pilot tone output GPIOs: 8 x inputs, 2 x outputs Latency: 4 – 260 msec (depending on processing structure) Low latency AES output: 3 – 8msec IP network: 1 x RJ45 Ethernet for management 2 x RJ45 for AoIP with double-redundancy.
