- Main Features:
- Four Processing Structures: Five-Band, Low-Latency Five- Band, Ultra-Low-Latency Five-Band and Two-Band.
- Window-Gated AGC: Intelligent two-band window-gated AGC controls levels subtly and unobtrusively.
- RDS/RBDS: Onboard generator supports dynamic PS scrolling and IP access.
- Factory Presets: OPTIMOD 5750 has numerous factory presets included in delivery; Orban’s exclusive “Less-More” control simplifies creating your own signature sound.
- AES67/SMPTE ST-2110: Two redundant network interfaces are available for Audio-over-IP connections supporting AES67 and SMPTE ST-2110.
- Remote Control/Monitoring: OPTIMOD 5750 can be configured and controlled via any HTML5 web browser. SNMP v2 is also supported. Ember+ will be added in a future release.
- “True Peak” Limiter: The “True Peak” limiter in the digital processing path anticipates and controls peak levels following D/A conversion, a feature now required by many broadcasters.
- ITU BS.412 Multiplex Power Control: The defeatable ITU BS.412 Multiplex Power Controller constrains MPX power smoothly and reliably, ensuring compliance in countries that regulate it.
- ITU-R BS.1770-4 Loudness Control facilitates compliance with modern target loudness recommendations like EBU R128.
- Diversity Delay: An adjustable delay can be inserted in the FM and/or digital path to ensure time-alignment of the FM and HD Radio/DAB+ signals at the receiver.
- Silence Detection: A programmable silence detector is available for the analog, digital and AoIP inputs. It can generate alarms and allows automatic switching to a backup input/input audio storage.
- Audience Measurement: Two internal watermarking encoders that support Nielsen Audio, Kantar, or IPSOS are optionally available, allowing the FM and the DAB+/HD Radio signals to be watermarked independently.
- Specifications:
- Streaming Monitor Output: Optionally, the 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 unavailable.
- μMPX interface: The optional μMPX Interface allows you to transmit bandwidth-limited DMPX over IP.
- APTmpX Interface: The optional APTmpX Interface allows you to transmit full bandwidth DMPX over IP.
- Internal Storage for Audio Backup: An optional 2 GB Flash Memory provides two hours linear or twelve hours AAC, MP3 or OPUS encoded audio.
- Internet Stream Decoder: This optional feature can be used as a backup audio source received via Audio-over-IP.
- Dual Power Supplies: OPTIMOD 5750 is equipped with monitored dual-redundant power supplies to ensure 24/7 operation.
- Safety Bypass Relays: The analog, digital AES3 and the composite audio inputs and outputs have defeatable safety bypass relays that operate in case of hardware or power failures. Audio Input Channels: • 1 x stereo analog • 2 x stereo digital AES3 • 2 x stereo AoIP
- Audio Output Channels: • 1 x stereo analog • 2 x analog MPX/composite • 2 x stereo digital AES3 or 1 x stereo digital AES3 and 1 x DMPX (configurable) • 4 x stereo AoIP • 1 x headphone output (for monitoring) • Optional 1 x μMPX (DMPX over IP) • SCA Inputs: 2 x
- Synchronisation: • 10 MHz clock input • AES11 sync input • 19 kHz pilot tone reference output • GPIOs: 8 x inputs, 2 x outputs
- Latency: • 4 - 22 msec (depending on the processing structure) • Low-latency AES Output: 3 - 8 msec
- IP Network: • 1 x RJ45 Ethernet Management • 2 x RJ45 Dual-redundant AoIP (AES67, SMPTE ST-2110, DANTE or RAVENNA)
