FOURTH SERIES LOW POWER
The TRedess Fourth Series Low Power is a family of air cooled UHF Transmitters and Gap Fillers, which bring together high quality performance, modularity, flexibility, outstanding compactness and smart installation and operation, thanks to its all-in-a-box standalone architecture (exciter and amplifier on the same chassis). The TRedess Fourth Series Low Power provides output power ranges up to 400W and covers the DVB-T/T2 and ISDB-T/Tb standards, for both MFN and SFN networks.
Transmitters can also work in Regenerative Transposer mode. Gap-fillers can work as MFN Transposer, or in SFN On-channel Repeater mode, using TRedess’ DEEC, the best echo canceller in the market.
Fourth Series ultra-compact units (up to 75W in 1U, up to 150W in 2U, and up to 400W (Ultra-Wide Band Doherty) in 3U, are ideal for scenarios with space limitation at the site.
Thanks to Ultra-Wide-Band Doherty technology, important cost reductions in energy consumption can be achieved without impacting in a truly smart operation and maintenance.
High level of compactness: 10W, 40W and 75W in a 1U rack unit. 150W in a 2U rack unit. 300W (Class AB) and 400W (UWB Doherty) in a 3U rack unit.
Ultra-Wide-Band Doherty for 400W transmitters: energy efficiency with same HW for the entire UHF TV band
DVB-T/-T2 and ISDB-T/-Tb modulations supported. MFN and SFN operation.
Extractable hot-plug PSU in 275W and 400W units, optionally redundant.
2xTS over IP inputs and 2xASI inputs (default) with seamless switching.
Digital linear and non-linear pre-correction.
Built-in echo canceller DEEC able to guarantee: Gain Margin = 24 dB. Doppler echo cancellation. Configuration of selective window up to 37 us.
Example: cancellation of an echo 20dB higher than the signal with DEEC echo canceller, with output MER > 27dB.
