SHURE / SLXD4Q+JB

The SLXD4Q+ Quad-Channel Receiver is a receiver for the SLX-D series that allows for the simultaneous use of four channels. Despite supporting four channels, its 1U size enables space-saving when rack-mounted. It is ideal for situations requiring the simultaneous use of four microphone signals, from lectures to live entertainment.

■Features
4-channel receiver fits within a 1U rack space
Wide frequency range of 20Hz–20kHz (varies by microphone)
Supports up to 10 simultaneous channels in the B band (Japan)
24-bit clear digital audio
118dB dynamic range
Audio summing function allows mixing and output of multiple channels as needed
RF cascade function enables an 8-channel system by connecting two SLXD4Q+ units
Supports bias voltage supply
Digital predictive switching diversity
Easy transmitter-receiver pairing with infrared scan and sync
Equipped with four XLR outputs, a 1/4-inch output, and two Ethernet ports
Compatible with Shure Wireless Workbench® software
Durable metal chassis
