• This configuration comes with a black subminiature UL4 UniPlex lavalier microphone optimized for speech intelligibility and equipped with a cardioid polar pattern that helps to reject unwanted noise.
• The advanced 1.6mm Shure Plex cable lasts longer than competing cables due to a dual redundant ground, which doubles as a secondary shield. It also offers virtually zero memory effect, won’t kink, and is fully paintable. 
• The lavalier mic plugs securely into the locking TA4M connector on the compact and discreet SLXD1 bodypack transmitter. 
• The rugged, plastic transmitter has a belt clip that attaches to the talent’s clothing and an LCD that shows essential information.
• The mic offset function provides up to +21 dB of gain to boost low-volume speech and ensure multiple microphones are at similar levels.
• Engage the 150 Hz high-pass filter to reduce distracting, unwanted low-end for clearer speech.
• A selectable 1/10mW RF output allows you to increase the transmission power to overcome interference, if necessary, and the system provides a transmission range up to 330'.
• Two AA batteries or an SB903 rechargeable battery (available separately) will power the unit for up to 8 hours.

• The SLX-D delivers 24-bit digital audio with a fast transient response and over 120 dB of dynamic range—resulting in clear, accurate sound.
• The system operates in the G58: 470 to 514 MHz UHF band with a 44 MHz tuning range and 1760 selectable frequencies, far away from potential Wi-Fi interference in the 2.4 GHz band.
• Digital Predictive Switching Diversity uses a microprocessor to switch between the two antennas for the cleanest signal—before dropouts occur.
• With a low latency of 3.2 ms, the system is ideal for applications that require live sound reinforcement.
• The SLX-D's spectrum-efficient digital transmission technology allows for up to 32 mics to be used at once.
• Up to 10 compatible systems per 6 MHz TV band and 12 systems per 8 MHz band are supported.
• Ethernet networking saves you time with coordinated group scanning between multiple receivers from a single location; TCPI command streams from third-party companies such as AMX and Crestron are also supported.

• Housed in a tough, half-rack metal chassis with detachable antennas, the SLXD4 receiver is a great fit for A/V installations or as part of a portable rackmount rig—ready to travel to a meeting, event, or performance.
• The SLX-D is engineered to provide outstanding sound for small- to medium-sized spaces and facilities—without costly, complicated features required primarily for large venues.
• Intuitive front-panel controls and a high-contrast LCD screen with audio and RF meters makes setup a snap.
• The auto-scan function automatically seeks out the cleanest available frequency for you. The receiver and transmitter then easily link to the same frequency via infrared.
• The receiver offers up to 60 dB of adjustable gain and the display shows you where the ideal level should be.

• Adding the SB903 lithium-ion rechargeable battery, along with an SBC10-903 single charger or an SBC203 dual-docking charger, offers a cost-effective and environmentally friendly alternative to throwing away AA batteries (battery and chargers available separately).
• Using the SB903 battery and SBC203 charger simplifies the task of keeping multiple transmitters charged and at the ready—you can even recharge the battery while still in the transmitter.
• When powered by an SB903, the transmitter displays the remaining battery life in hours and minutes.

• Adding UA874 active antennas or PA805SWB passive antennas increases the range of your system and offers increased protection against interference.
• The UA844+SWB antenna distribution system (available separately) lets you stretch the power of your antenna pairs, giving you more on-air channels in less setup time.

Shure offers numerous lavalier, headset, and handheld microphone options to adapt your SLX-D system as your needs evolve.

• The WL93 lavalier microphone features an omnidirectional polar pattern, which picks up sound evenly from all directions, allowing for flexible mic positioning.
• If you need a dust-resistant and waterproof solution, the DL4 DuraPlex is a rugged omnidirectional lavalier with an IP57 rating.
• The WL184 supercardioid lavalier mic offers a narrower, feedback-resistant pickup pattern for louder events.
• The discrete MX153 sub-miniature earset mic provides exceptional clarity in spoken word applications.
• The SM35 is a comfortable, durable headset microphone for active performance.
• The SLXD2 handheld transmitter is available with several mic capsules choices for presenters who prefer the flexibility of a handheld microphone.

Related Questions and Answers

Q: 1. Would this work on the 3.5mm adapter for the Gopro4 which is connected on the Gopro?

A: No - it is designed for devices offering a female 1/8 TRRS input like smartphones and tablets.

Q: 2. Is this compatible with a Sony A7?

A: Should work fine with this and most other HDSLR cameras and most camcorders as well.

Q: 3. Do these have auto shut-off? If so, can it be disabled?

A: No auto shut off. I agree with Bob B.: always charge units before using. They don't seem to hold charge very well while in storage or non-use.

Q: 4. Is the 1/4' output labeled Instrument out a line level output?

A: The manual shows the 1/4 inch output as -13 dBV into a 100K ohm load. With consumer line level at -10 dBV it's close but not quite line level.

Q: 5. Shure BLX 1288/CVL-J10 is this rack mountabled??

A: No it isn't. I used a 1U rack shelf and used command strips to secure it.

Q: 6. Can I use ASA 214 (Antenna Spliiter from Sennheiser or other models) for use with 4 systems/receiver EM-XSW2?

A: The Sennheiser ASA-214 is designed for Sennheiser ew G3 and ew G4 Receivers and is not compatibbe with the Sennheiser XSW2-ME2 Wireless Lavalier Microphone System (A: 548 to 572 MHz) BH #SEXSW2ME2A.

Q: 7. Would this work with a digital voice recorder? (i.e. Olympus WS-822?) Thanks!

A: No. It is compatible with mobile phones or tablets that offer a 1/8 TRRS Connector

Q: 8. Can you record on 2 separate channels (left and right) like the Comica BoomXD?

A: No. The receiver in this kit provides a summed mono output.

Q: 9. Am I reading correctly that this system can support both mics transmitting at the same time/same channel?

A: This system features a dual receiver, so both mics can operate at the same time, but they have separate outputs, which would go into two channels of a mixer. The Samson Concert 288 All-In-One Dual-Channel Wireless System (H-Band, 470 to 518 MHz), BH #SASWC288ALLH does offer a mixed output, if you require a single output to your mixer or portable speaker.

Q: 10. Can I add handheld microphones?

A: This is a single channel receiver, you can use a handheld with it as long as it's made by Sennheiser and it runs in the same frequency, however you wont be able to use both the lavalier and handheld at the same time.
