Description
Designed for capturing audio, the Shure QLXD4 Digital Wireless Receiver offers 24-bit digital audio quality and solid RF spectrum reception. When paired with a wireless transmitter and microphone, it can be used for mid-size events and installations in businesses, hotels, government offices, schools, houses of worship, live performance spaces, and more. It features more than 60 preset channels per frequency band, network control, and AES 256-bit encryption. The QLXD4 wireless receiver is built with switching diversity and automatic channel scan, and has IR one-touch sync capabilities to make finding an open frequency quick. This receiver features a 20 Hz to 20 kHz frequency range, and a high-contrast LCD display. This allows for clear navigation though the menus and controls. With clearly defined performance, the QLXD4 delivers clean audio and provides professional features for demanding live sound events and installations.
The QLXD4 receiver is built with two detachable 1/2 wave antennas and has balanced 1/4" line outputs, and XLR balanced output connectors. The XLR outputs are switchable from mic/line. Ethernet networking enables networked channel scanning across multiple receivers. Wireless Workbench software allows for remote control of receiver settings from a PC or Mac. Included are a PS23 power supply, two 1/2 wave antennas, two 2' BNC cables with bulkhead adapters, Ethernet cable, and rackmount hardware.
