Product Overview
The SLXD14/93 features the WL93 miniature omnidirectional lavalier microphone and the SLXD1 transmitter. It provides transparent digital audio and rock-solid RF stability for lecture halls and live performances.
The SLXD14 Wireless System delivers transparent, 24-bit digital audio and rock-solid RF performance for a wide range of applications, from day-long presentations to nighttime performances. Operate up to 32 compatible systems per 44 MHz band, with easy setup and optional rechargeability accessories for wireless excellence, wherever required. Ships with SLXD4 single-channel receiver, SLXD1 bodypack transmitters and WL93 miniature omnidirectional lavalier microphone with antenna, rackmount accessories and 2 AA batteries.
All WL93 models are supplied with a mounting block with attached tie bar, a sew-on mounting bracket and an acoustic windscreen to minimize wind noise in outdoor applications. All WL93 models include a cable terminated with a 4-pin mini connector which connects directly to a Shure wireless body-pack transmitter.
