Shure BLX14R/W93 Wireless Rack Mount Presenter System w/ WL93

The Shure BLX14R/W93 (BLX14R-W93) is a rack-mount wireless presenter system with a WL93 miniature lavalier microphone, for presenters, classrooms, houses of worship and installed sound racks. It has up to 300 ft (91 m) line-of-sight range, runs up to 14 hours on two AA batteries, and supports up to 12 compatible systems per frequency band.

The kit pairs the BLX1 bodypack transmitter and WL93 lavalier with the BLX4R half-rack, single-channel receiver. The BLX4R has rugged metal construction, XLR and 1/4 in outputs, an adjustable output level, an LCD with RF and audio metering, and microprocessor-controlled internal antenna diversity. One-touch QuickScan finds the best open frequency, and the removable antennas and included rack hardware make it simple to mount in an equipment rack. This listing is the H9 band (512 to 542 MHz).

Does the BLX14R/W93 mount in a rack?

Yes. The BLX4R is a half-rack receiver and the rack mount brackets, link bracket and antenna front-mount kit are included, so it mounts in a standard equipment rack.

How far can the presenter walk from the receiver?

Up to 300 ft (91 m) with clear line of sight. Actual range depends on RF signal absorption, reflection and interference at the venue.

How long do the batteries last?

Up to 14 hours from two AA alkaline batteries in the BLX1 bodypack.

How many systems can I run at once?

Up to 12 compatible BLX systems per frequency band, depending on region and the RF environment. QuickScan picks a clear frequency for each one.

Which BLX presenter system should I choose?

All share the BLX1 bodypack, 300 ft range and 14-hour AA battery life, so the difference is the microphone and the receiver. The BLX14R/W93 uses the clip-on WL93 lavalier with the rack-mount BLX4R. The BLX14R/MX53 swaps in an MX153 earset microphone, and the BLX14R/SM35 uses an SM35 headset. The BLX14/CVL pairs a CVL lavalier with the tabletop BLX4 receiver instead of a rack unit.
