- Main Features:
- AM Operating Mode: With OPTIMOD Trio you can achieve excellent quality in AM shortwave, medium wave and long wave broadcast sound. It increases the density and loudness of the program material by Orban’s proprietary multiband limiting and multiband distortion-canceling clipping, improving the consistency of the station's sound and increasing loudness and definition without producing audible side effects. OPTIMOD Trio compensates for the high frequency rolloffs of typical AM receivers with a fully adjustable program equalizer providing up to 20dB of high-frequency boost (at 5 kHz) without producing the side effects encountered in conventional processors.
- FM Operating Mode: OPTIMOD Trio provides four FM processing structures: Five-Band, Low-Latency Five-Band, Ultra-Low-Latency Five-Band and Two-Band. Additionally, it can be also used as stand-alone stereo encoder with latency as low as 2 msec and full overshoot limiting in both the left/right and composite baseband domains. The defeatable ITU BS.412 Multiplex Power Controller constrains MPX power smoothly and reliably, ensuring compliance in countries that require it. An onboard RDS/RBDS generator supports dynamic PS scrolling and IP access. The optional μMPX Interface allows you to transmit DMPX over bandwidth reduced IP.
- Digital Media Operating Mode: You can choose between the Five-Band processing structure for a spectrally consistent sound and the Two-Band processing structure for a transparent sound that preserves the frequency balance of the original program material. Either processing structure delivers artifact-free loudness control. Orban’s proprietary PreCodeTM technology minimizes artifacts caused by low bitrate codecs often used in HD RadioTM, DAB+, and streaming.
- Factory Presets: Like all OPTIMODs, Trio also comes with a variety of factory presets; Orban’s exclusive “Less-More” control simplifies creating your own signature sound.
- AES67/SMPTE ST-2110: Trio provides an Ethernet network interface for Audio-over-IP connections supporting AES67 and SMPTE ST-2110.
- Remote Control/Monitoring: OPTIMOD Trio can be configured and controlled via any HTML5 web browser. It also supports the SNMP v2 protocol and in a future release Ember+ will be added.
- ITU-R BS.1770-4 Loudness Control facilitates compliance with modern target loudness recommendations like EBU R128.
- 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.
- Streaming Monitor Output: The processed signal can be optionally monitored remotely via IP, allowing processor adjustment in locations where a clean off-air signal is unavailable.
- 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.
- Audience Measurement: An internal Watermarking Encoder can optionally be added (Kantar, Nielsen or IPSOS).
- Dual Power Supplies: OPTIMOD Trio is equipped with monitored dual-redundant power supplies.
