About the Shure QLXD14/85-G50

Hi-res quality

If you're familiar with high-quality sound reinforcement, you already know Shure's reputation for sound quality and dependability. Now Shure has taken the next step with the QLX-D family of wireless microphone systems. With 24-bit resolution, you'll get superior sound quality in a convenient, rugged, and dependable system.

Hi-res quality

If you're familiar with high-quality sound reinforcement, you already know Shure's reputation for sound quality and dependability. Now Shure has taken the next step with the QLX-D family of wireless microphone systems. With 24-bit resolution, you'll get superior sound quality in a convenient, rugged, and dependable system.

Extra time

The QLXD1 bodypack transmitter offers up to 10 hours of operation with Shure's SB900A rechargable lithium-ion battery (sold separately) and 9 hours with two standard AA alkaline batteries. With up to 330 feet of broadcast range, it'll work on large stages where the transmitter and receiver are far apart. The system frequency options are organized in groups with multiple channels, each of which is tuned to a specific frequency; you also have the option of creating custom channel groups. 

There are three methods of matching the frequencies of the transmitter and receiver:

  • automatic scanning that chooses the best available receiver frequency group/channel and tunes the transmitter to the receiver via infrared scanning;
  • manual selection by frequency group/channel;
  • manually tuning the transmitter and receiver to the same frequency.

You can run up to 17 compatible systems simultaneously in the 6MHz range and up to 21 channels in the 8MHz range.

In control

This QLX-D system allows Ethernet networking via Shure's free Wireless Workbench software, available in Windows- and Apple-compatible versions as well as by their ShurePlus™ Channels app for iOS devices. The system also works with AMX and Crestron controls systems via Ethernet cables.

Shure's WL185 lavalier microphone gives you hands-free operation with maximum freedom of movement. The lightweight mic clips securely to your clothing. Its cardioid pickup pattern rejects off-axis ambient noise to keep your voice clear. Rugged metal cases for the receiver and bodypack transmitter resist accidental breakage and are much more durable than the plastic cases used in many wireless systems 

When you need the best possible fidelity and hands-free miking, this QLXD14/85 system gives you the best of both functions in a compact, tough package that's built to take it.

Product Research



Overview: The Shure QLX-D Digital Wireless microphone system offers streamlined performance with transparent 24-bit digital audio designed for presentations, lectures, houses of worship, conference centers, and mid-size live sound events. Operating in the 470 - 534MHz range, the QLX-D has a working range of up to 330 feet (line-of-sight).

24-Bit Digital Audio: Shure digital wireless technology allows the QLX-D to transmit detailed audio with an extended, virtually flat frequency response from 20Hz to 20kHz (microphone dependent), and with up to 120dB of dynamic range. Designed to be highly RF spectrum efficient, the QLX-D can operate up to 168 compatible channels per frequency band with up to 72 MHz of tuning bandwidth (region dependent). It also allows up to 17 compatible systems in the 6MHz TV band and 22 systems in the 8MHz TV band.

AES-256: The QLX-D uses the Advanced Encryption Standard (AES-256) to protect audio signals transmitted to the Receiver. When encryption is enabled, the Receiver generates a unique encryption key which is shared with the Transmitter during an IR synchronization. The Transmitter and Receiver share an encryption key to form a protected audio path, preventing unauthorized access by other receivers. The Transmitter and Receiver will remain encrypted until manually deactivated, even after powering off and back on again.

Channel Setup: A wireless audio channel is formed when the Receiver and Transmitter are tuned to the same frequency. To make setup easier, frequencies available to the QLX-D system are organized into Groups and Channels. Each Group contains a number of channels and each channel is assigned to a specific preset frequency. The QLX-D provides 3 methods for matching the Receiver and Transmitter to the same frequency:

  • IR Sync: The IR Sync feature will automatically tune the transmitter to match the receiver frequency, forming a wireless audio channel. By simply powering the Receiver and Transmitter on, with the two IR sync windows within 6 inches of each other, and pressing the Sync button on the receiver, the Transmitter will automatically be tuned to the Receiver frequency.
  • Manual Group & Channel Assignment: The Receiver and Transmitter can manually be set to the same Group and Channel number to form an audio channel.
  • Manual Frequency Assignment: The Receiver and Transmitter can be manually set to the same frequency rather than using Groups and Channels to form an audio channel.

Network: The QLX-D features a rear-panel RJ-45 port for connecting into a network via an Ethernet connection. The Shure Receiver includes an internal DHCP client allowing for automatic network configuration when connected to a DHCP-enabled router. The IP address and subnet mask can also be manually configured from the menu system or from a computer on the same network using Wireless Workbench 6 (WWB6) software, available here for MacOS X (El Capitan, Sierra, and High Sierra) and Windows (7, 8, & 10).

WWB6: Shure's Wireless Workbench 6 allows comprehensive monitoring and control of networked Shure wireless systems from your computer, allowing for real-time changes to device and channel parameters. WWB6 includes a powerful set of frequency coordination and visualization tools for calculating compatible frequencies for all wireless systems, facilitating quick and easy configuration, operation, and monitoring of your wireless system.

    • Green LED (Network Status): Off = no network link, On = active network link. Flashing = corresponds to traffic volume.
  • Receiver Reset: Pressing this restores the Receiver back to default settings.
  • XLR Output: A male XLR socket provides a balanced mic- or line-level signal output.
  • Instrument/Auxiliary Output: An unbalanced 1/4" socket can output either mic- or line-level signals.
  • Mic/Line Switch: Determines the signal level output from both the XLR and 1/4" jacks.
  • Antenna A/B: Two BNC sockets are provided for the two 13.75" antennas. Both antennas can be swiveled and tilted for optimal reception.

  • Battery Type: Allows you to select the installed AA battery type to ensure accurate battery power metering.

WL185 Microphone: The QLX-D wireless system includes a WL185 lavalier microphone, designed for general purpose sound reinforcement applications requiring good rejection of ambient noise. The mic features a cardioid polar pattern with a 130˚ pickup angle, and a cartridge that can be interchanged with other optional cartridges (sold separately) for use in a variety of applications. The WL185 includes two snap-fit foam windscreens (large and small) along with a lapel-clip for attaching the mic to a shirt or blouse.
