The QLXD4 is the receiver of the digital QLX-D wireless system that combines professional functionality with easy installation and operation. Automatic Channel Scan quickly finds the cleanest frequencies, while the Networked Channel Scan splits these open frequencies between multiple receivers over Ethernet with the simple one-button synchronization. Predictive diversity ensures a stable RF wireless connection. The use of the RF spectrum is very efficient: up to 22 transmitters can be used per 8 MHz channel at the same time. The eavesdropping-proof AES 256-bit encryption guarantees radio transmissions with the highest security and data protection. The QLX-D Receiver can be remotely controlled via PC and Mac computers using the Shure Wireless Workbench® software or the iOS app ShurePlusTM Channels. For easy installation in professional environments, the receiver is in 9.5" rack format with detachable half-wave antennas.
