Mã sản phẩm: QLXD4

Digital wireless receiver combines professional features with streamlined set-up and operation. Features include Automatic Channel scan, Networked Channel Scan, digital predictive switching, and AES 256 encryption for security.

  • Automatic Channel Scan quickly finds clear frequencies; Networked Channel Scan then shares open frequencies between multiple receivers over Ethernet, with one touch syncing
  • Digital Predictive Switching Diversity ensures a stable RF connection
  • Highly efficient RF spectrum usage – up to 22 transmitters per 8 MHz channel
  • Secure AES 256 bit encryption of all wireless transmissions
  • Shure Wireless Workbench® software allows remote control from PC or Mac
  • ShurePlus™ Channels mobile app allows remote control from iOS devices
  • Half rack format with detachable ½ wave antennas
  • Up to 60 dB of adjustable audio gain 
  • Up to 72 MHz tuning bandwidth (region dependent)
  • More than 60 pre set compatible channels per frequency band (region dependent)
  • High contrast LCD menu and controls with lockout feature, plus Audio and RF LED meters with peak indicator
  • Mic / line switchable XLR output, and 6.3 mm instrument output
  • Durable aluminium construction with brushed finish
