OPTIMOD 5750 HD

Based on the popular OPTIMOD 5750 processor, the 5750 HD provides FM/HD1 processing and includes a second independent processing chain called HD2 for DAB+, HD Radio and Streaming. It comes in a compact 1 RU design and is equipped with a high-resolution touch display and can be controlled remotely via any HTML5 web browser.

OPTIMOD 5750 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.

An intelligent two-band window-gated AGC using Orban’s patented “master / bass” band couplingcontrols 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 5750 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 operationto ensuring maximum uptime.

The OPTIMOD 5750 HD is targeted for availability in Q4 2024.
