The Shure SLXD14/DL4B offers actors, performers, instructors, clergy, and presenters a wireless lavalier microphone system that's easy to set up and dependable, which delivers crystal-clear digital sound quality. Built around a rugged, single-channel, half-rack receiver with removable antennas, the system is ideally suited for portable rigs or long-term installations in small- to medium-sized venues, event spaces, conference rooms, houses of worship, and education facilities.

The SLX-D operates in the UHF band to transmit high-quality, 24-bit digital audio with over 120 dB of dynamic range for crisp, detailed sound. It utilizes Digital Predictive Switching Diversity to protect the transmission from interference and deliver a solid, reliable RF signal without dropouts.

This configuration comes with a black DL4 DuraPlex waterproof miniature omnidirectional lavalier microphone built to withstand the rigors of professional use. The discreet bodypack transmitter has a selectable 1/10mW RF power output and a transmission range up to 330'. It provides up to 8 hours of operation on two AA batteries or an SB903 rechargeable battery (available separately).

The all-metal, rackmount SLXD4 receiver features an intuitive LCD interface with meters for RF, battery status, and audio output. It also offers 60 dB of gain control, and both mic/line XLR and 1/4" instrument outputs. Additional features include automatic frequency scanning and IR sync to easily link the transmitter and receiver to the same frequency.

With up to 32 mic channels available at the same time, the SLX-D is ready to expand as your needs grow. What’s more, setting up multiple systems is made fast and easy via the Ethernet port, which links the receivers together for quick, coordinated frequency scans from a single location.

Q: 9. Can you use both the microphones at the same time (body pack and handheld)?

A: No, you cannot use both microphones (the bodypack and handheld) at the same time because the Shure SLXD4 receiver that comes with the Shure SLXD124/85 Digital Wireless Combo Microphone System (G58: 470 to 514 MHz) is single channel.

Q: 10. What is the difference from the EW 512P to the EW 100? - In other words, why is there such a price difference?

A: The ew 512P system has a wide 88 MHz bandwidth with 3520 frequencies and an adjustable RF output level of 10, 30 or 50 mW. Depending on your location, you can operate up to 32 wireless systems simultaneously. The ew 100 has a 42 MHz bandwidth with 1680 frequencies and a fixed RF output level of 30 mW. You can use up to 12 ew 100 systems at the same time depending on the environment. The ew 512P includes the MKE 2 lavalier which is a more professional mic than the ME 2-II (or ME 4) which is included with the ew 100 system. Additionally, the ew 512P has a headphone jack on the receiver but the ew 100 does not have a headphone jack. The ew 100 system also includes a plug-on transmitter (SKP 100) for use with dynamic mics and mics that do not require phantom power. If you do want to add on a similar plug-on transmitter for the ew 512 or use the ew 500 system, the SKP 500 does supply +48V phantom power.
