Product Details

Wisycom MRK980 Two Channels Ultrawide Band Receiver

The Wisycom MRK980 Two Channels Ultrawide Band Receiver offers exceptional flexibility and performance for wireless microphone systems. Its 1090MHz switching bandwidth within the 170-1260 MHz range, combined with superior selectivity and intermodulation immunity, ensures optimal operation. The MRK980 boasts an internal DSP processor, Wisycom’s Multicompanding system, Dante compatibility, and a redesigned user interface for quick and easy setup.

 

 

Key Features:

  • Dual-Channel True Diversity: Full DSP processing.
  • Ultra-Wideband Tuning: 1090 MHz bandwidth within 170-1260 MHz.
  • Push-to-Talk (PTT) Ready: Dedicated outputs (optional).
  • Versatile Outputs: Analog, AES/EBU, and Dante (with redundancy).
  • Seamless Dante Integration: Machine Synchronized mode eliminates sample rate delay.
  • Next-Gen Multiband Front-End Filtering: High Q moving filters in 170-230 MHz, 470-800 MHz, and 960-1160 MHz (DME) or 806-810 MHz (Japan). Country-specific SAW filters available (USA 940-960 MHz or Japan 1240-1260 MHz).
  • Selectable DSP-FM Operation: Wideband and Narrowband modes. Narrowband increases band efficiency (200/250 kHz channel density) and provides approximately 3dB improved sensitivity and noise immunity.
  • Low-Noise VCO: Ultrafast spectrum scan for quick and easy setup.
  • High-Contrast OLED Display: Clear and easy to read.
  • Flexible Control: Monitor and control via USB and Wisycom Manager 2.0 software.
  • Expansion Slot: For GPIO or future features.
