The SLXD4Q+ is a quad-channel rack-mount receiver from the Shure SLX-D+ wireless platform. Capable of running four independent wireless channels from a single 1U rack space, it is designed for high-density deployments in corporate events, theatrical productions, broadcast, and large-scale live sound.

Four Channels, One Rack Unit

All four receiver sections deliver full 24-bit digital audio with over 118 dB dynamic range simultaneously, making the SLXD4Q+ a high-efficiency solution for productions requiring multiple independent wireless channels with minimal rack footprint.

Intelligent Frequency Coordination

Automatic Setup finds and assigns clean frequencies for all four channels simultaneously, while compatibility for up to 32 simultaneous channels per band allows the SLXD4Q+ to work cleanly alongside other wireless systems in the same venue.

Remote Transmitter Control

ShowLink® Ease enables real-time monitoring and adjustment of all paired transmitters — gain, mute, and lock settings — directly from the receiver panel, streamlining management of complex multi-channel setups.
