BLX4R receiver
A lightweight receiver designed for rack mounting.

Independent shopping perspective
This J11 vocal wireless system puts a BLX2 handheld transmitter with a BETA 58A capsule alongside Shure’s lightweight, rackmountable BLX4R receiver. That format works cleanly where the receiver belongs in an equipment rack instead of on a tabletop. The neodymium-element capsule is described as crisp and clear, and the BETA 58 is noted for hotter output and improved response than the SM58. It is a focused rack-receiver configuration for handheld vocal wireless use.
