Modular Wireless Microphone Receiver System

The system presents exceptional selectivity and inter-modulation immunity for best operating performance of the wireless-microphone system even in the presence of DVTB-T transmitter signals.

FEATURES

  • Wide bandwidth: up to 370 MHz with tunable filters (2 channel’s independent)
    470 MHz to 840 MHz (Europe TV ch. 21/67) with internal active splitter
  • Extreme immunity: IIP3 > 20dBm, practically intermodulation free
  • Powerful and quick: thanks to the latest DSP class shark by Analog Design (2Gigaflops 40bit power), providing the highest audio quality (40bit floating point) and a delay of only 0,39 msec (AES3 output) and 0,46 msec (analogue output)
  • Audio quality: Analogue (electronically balanced) and digital output (AES3)
  • Network: 2 USB connectors for configuration/monitor and cascade rack connections and a Ethernet 10/100 base TX port (RJ45) for network connection
  • Automatic scan: for best channels, squelch and other automatic setup
  • Infrared interface (i.e. for system setup, microphone programming)
  • Automatic reprogramming of transmitter (thru infrared)
  • PC Software to monitor/setup units, spectrum analyzer mode, intermodulation free frequencies calculator, embedded database by area or to archive existing setups
