Overview
Orban Optimod 5950 HD2 FM & DAB+/HD1/HD2 Radio Audio Processor
Based on the popular OPTIMOD 5950 processor, the 5950 HD provides FM/HD1 processing and includes a second independent processing chain called HD2. It comes in a compact 1 RU design, is equipped with a high-resolution touch display, and can be controlled remotely via any HTML5 web browser.
OPTIMOD 5950 HD is equipped with analog, AES3, composite and digital MPX as well as AES67/SMPTE-ST2110 inputs and outputs includes advance audio routing and Diversity Delay and can easily be integrated in any studio and transmitter environment. Additionally, optional μMPX allows a cost-effective transmission of digital MPX signals over IP.
The FM section offers four processing structures which can be selected depending on the user’s application and requirements: Five-Band, Low-Latency Five-Band, Ultra-Low-Latency Five-Band and Two-Band. It also features the legendary Orban MX limiter which provides increased apparent loudness at significantly lower distortion.
An intelligent two-band window-gated AGC using Orban’s proprietary “master / bass” band coupling controls the levels subtly and unobtrusively. Where three kinds of stereo enhancement, an advanced EQ section, Enhancers and extensive kind of other parameters are available to create a signature sound.
The “True Peak” limiter in the two HD processing chains anticipates and controls peak levels following D/A conversion, a feature now required by many broadcasters.
The defeatable ITU BS.412 Multiplex Power Controller constrains MPX power smoothly and reliably, ensuring compliance in countries that regulate it.
OPTIMOD 5950 HD provides ITU-R BS.1770-4 Loudness Control which facilitates compliance with modern target loudness recommendations like EBU R128 for each processed FM and HD output source if needed.
Multiple audio input and output sources can be monitored via the front panel headphone output and the optional IP Monitoring Streaming Encoder.
The optional Internal Audio Backup player or IP Audio Backup decoder can be used as one of the emergency fallback scenarios, but it can also be used as a main Streaming Input source like HLS
OPTIMOD 5750 HD supports SNMP v2 and Ember+ protocol and Remote Control Interface for professional monitoring purposes and has dual power supplies with independent AC line inputs provide redundant operation to ensuring maximum uptime.
Features
- Six Processing Structures:Five-Band, Low-Latency Five-Band, Ultra-Low-Latency Five-Band, Two-Band, Five-Band MX and Two-Band MX.
- 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:Like all OPTIMODs, the 5950 also comes with a variety of factory presets; 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, RAVENNATMand SMPTE ST-2110. AES67 provides Dante and Livewire+TMcompatibility.
- Remote Control/Monitoring:OPTIMOD 5950 can be configured and controlled via any HTML5 web browser. It also supports the SNMP v2 and the Ember+ protocols.
- Measurement Tools:The HTML5 web browser control user interface offers a complete tool set to measure and monitor your audio signals including oscilloscope and FFT displays.
- Audience Measurement:Two internal Nielsen or Kantar Encoders are optionally available, allowing the FM and the DAB+/HD Radio signals to be watermarked independently.
- Streaming Monitor Output: 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 DMPX over IP.
- Internal Storage for Audio Backup: A 2 GB Flash Memory provides two hours linear or twelve hours AAC, MP3 or OPUS encoded Audio.
- 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 in the FM and/or digital path to ensure time-alignment of the FM and HD Radio/DAB+ signals at the receiver.
- “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: For countries requiring the multiplex power to be constrained to a specified limit, this feature can be activated to ensure compliance while controlling MPX power smoothly and reliably.
- ITU-R BS.1770-4 Loudness Control facilitates compliance with modern target loudness recommendations like EBU R 128.
- 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.
- Dual Power Supplies:OPTIMOD 5950 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
