Frequently Asked Questions
Can the QLXD124/85 receiver operate both the handheld and bodypack transmitter at the same time?
No. The QLXD4 receiver has a single channel, so it can receive from either the SM58 handheld transmitter or the QLXD1 bodypack at any given time, but not both simultaneously. You would need a second receiver for dual-channel operation.
What frequency band does the G50 designation cover?
The G50 band covers 470–534 MHz. It is important to verify that this frequency range is approved for use in your region and does not conflict with local broadcast or licensed spectrum allocations.
Does the QLXD124/85 system include encryption for secure audio transmission?
Yes, it features AES-256 encryption, which prevents unauthorized listeners from intercepting the wireless audio signal—an important feature for corporate events, government settings, and broadcast applications.
How does the one-touch sync function work on the QLXD4 receiver?
The QLXD4 scans for open frequencies in the selected band, then you hold the transmitter near the receiver's IR sync window and press the sync button. The receiver automatically assigns the clean frequency to the transmitter without manual programming.
Can I monitor and adjust receiver settings remotely?
Yes. The QLXD4 supports Ethernet networking for integration with Shure Wireless Workbench software on PC or Mac, and you can also monitor channels remotely from iOS devices using the ShurePlus Channels Mobile App.
