BLX4R Wireless Receiver for BLX-R Wireless System

Rack mount analog wireless receiver provides improved linearity and frequency response with group and channel scan for easy set-up. Features include frequency QuickScan, adjustable output levels, and two-color audio status indicator LED.

Product Details

How many musicians can use this system simultaneously?

Up to 12 compatible channels per group with group and channel scan for easy set-up.

Is the setup really that easy?

Yes, with one button you can start the group and channel scan, which gives you the best open frequency. Adjust the transmitter to the same channel and you’re ready to go.

Is a rack mount kit included

Yes, the box contains everything you need for rack mounting.

What does “Linearity” mean?

The proportion between input signal of the transmitter and output signal of the receiver is always constant.

How does the BLX receiver perform compared to wired?

The frequency response of the wireless microphone is almost identical to the frequency response of a wired mic. Also the dynamic performance is almost the same.
