Shure SLXD14D+

The SLXD14D+ is a dual-channel digital wireless system built around a half-rack SLXD4D+ receiver and two SLXD1+ bodypack transmitters. Each bodypack carries a locking 4-pin (TA4M) input that accepts a wide range of Shure lavalier, headset, and earset microphones as well as instrument cables for guitar or bass, so one system can cover a presenter and an instrumentalist at the same time. Transparent 24-bit digital audio and greater than 118 dB of dynamic range keep speech and performance clean from the stage to the mix.

An expanded wide-tuning range of up to 138 MHz (region dependent) simplifies frequency coordination and lets more systems share a crowded RF space, while AES-256 encryption protects the link. The two bodypacks run up to 8 hours on a pair of AA batteries, or accept the optional Shure SB903 lithium-ion pack for runtime metering in hours and minutes. The system ships with the SLXD4D+ dual receiver and two SLXD1+ bodypack transmitters; microphones and instrument cables are chosen separately.
