Shure BLX4 Wireless Microphone Receiver for BLX Wireless System

The Shure BLX4 Wireless Microphone Receiver brings professional‐grade wireless audio to musicians with its M17 frequency range (662‐686MHz) and sophisticated microprocessor‐controlled internal antenna diversity. This robust receiver supports up to 12 compatible systems per group, making it perfect for bands and multi‐performer setups. The intelligent One‐touch QuickScan feature automatically locates the clearest available frequency, whilst the internal antennas provide up to 100m operating range without the risk of damage during transport or setup.

Setup couldn’t be more straightforward — a single button initiates the group and channel scan to find the optimal open frequency, then simply match your transmitter to the same channel. The BLX4 maintains exceptional linearity, ensuring the proportion between transmitter input and receiver output remains constant throughout your performance. With frequency response nearly identical to wired microphones and comparable dynamic performance, this wireless system doesn’t compromise on audio quality.

Practical features include both ¼” and XLR audio outputs for versatile connectivity, plus a two‐colour LED status indicator that shows green for normal audio levels and red when excessive levels occur. The microprocessor‐controlled antenna diversity and improved linearity make the BLX4 an ideal choice for musicians seeking reliable wireless audio without the complexity of professional touring systems.
