Artikelnummer: MKR980
Studio mottagare från WisyCom med bland annat Dante
Wisycom MRK980 is a true diversity, ultra-wideband dual channel receiver. With its 1090MHz of band switching, it ensures the users an exceptional band flexibility, combined with a superb selectivity and intermodulation immunity, for best operating performances of the wireless microphone systems. MRK980 also features an internal DSP processor, Wisycom famous Multicompanding system, new Dante compatibility and a completely and renewed user interface, which make this system easy and quick to setup.
FEATURES
Two channels true diversity receiver (full DSP processing)
Up to 1090 MHz bandwidth in 170/1260 MHz range
Push to talk (PTT) enabled with dedicated outputs (optional)
Analogue, AES/EBU & Dante outputs (with redundancy)
Dante machine Synchronized mode: no sample rate delay!
Next Gen Multiband front-end filtering:
High Q moving filter in 170-230 MHz
High Q moving filter in 470-800 MHz
High Q moving filter in 960-1160 MHz (DME) (or 806-810 MHz saw filter – Japan)
Country specific saw filters:
