• 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. How much bias voltage does the 112p G4 transmitter provide? Will it adequately power a DPA 4060 which requires at least 5V?

A: No, the Sennheiser SK 100 G4 Wireless Bodypack Transmitter included with the Sennheiser EW 112P G4 Camera-Mount Wireless Omni Lavalier Microphone System will supply up to 3V, so it is not a suitable match for use with the DPA Microphones 4060 CORE Omni Lavalier Microphone.

Q: 2. Will 1.5V Lithium rechargeable batteries work in the Sennheiser EW 112P G4?

A: Yes, the Sennheiser EW 112P G4 Camera-Mount Wireless Omni Lavalier Microphone System (A: 516 to 558 MHz) can be used with rechargeable lithium batteries.

Q: 3. Is this safe to use with the Verizon 5G frequency ban? The FCC says 600MHz, but it also says something about some ranges in the 500MHz frequency band as well.

A: The Sennhieser EW 112P G4 UHF wireless systems work within the FCC- allowed range of 470-608MHz. 5G cellular service operated on higher frequencies than this. Sennheiser wireless systems allow for auto scanning, with 1680 frequencies to choose from, making it easy to find a clean frequency, even in the crowded UHF spectrum. .

Q: 4. How does this system compare to the Sony UWP-D21?

A: You will get very similar quality and range out of either system and both are very highly preferred for professional applications. Either of these are great for using many wireless microphone systems in the same space and at the same time, without running into interference with each other. If you are only going to require a set up with one or two wireless microphones running at the same time, then I recommend considering something more like the Sennheiser AVX system because it will give you the same great quality and it is more compact as well, even though it is not quite as frequency agile as the above solutions.

Q: 5. Why am I receiving a warning that this product contains lead? I understand that my state requires a warning, however, what portion of this product contains the lead and is it dangerous?

A: Sennheiser has an office in California, and is legally required to place this warning on all their items regardless of whether they contain lead or not. This item is not dangerous.

Q: 6. in the specifications it says that the antenna connector is "1/4 Wire Antenna" but I have searched the internet and I have not found such a connector, what model is the connector, sma, crc9, fme, mcx or what? I need it because I want to extend the antennas

A: The antennas on the wireless components of the Saramonic UwMic9S Mini KIT2 Compact 2-Person Camera-Mount Wireless Omni Lavalier Microphone System are not designed or able to be replaced with external third party antennas such as paddles to extend or enhance their ability to receive transmitter signals.

Q: 7. What is the correct frequency version for Chicago IL?

A: Both frequency ranges offered for the Sennheiser EW 512P G4 Camera-Mount Wireless Omni Lavalier Microphone System appear to have available channels for the Chicago, Illinois area, however there may be slightly more available on the GW1: 558-608MHz range.

Q: 8. The manual says to set AF Out on the receiver to +18 dB. Is this true? Why not 0db?

A: In general, Camera preamps are not the best quality. +18db ensures that you will need the least amount of preamp gain possible, which will maximize the quality you capture with the camera.

Q: 9. What is the locking system for the lav mics? (Godox Proprietary, Sennheiser, Sony...)

A: The Godox WMicS1 Pro Kit 2 Two-Person Camera-Mount Wireless Omni Lavalier Microphone System uses the same 3.5mm TRS locking connector and wiring configuration as Sennheiser does for its lavalier microphones..

Q: 10. Does this have a filter to keep motion/occupancy sensors from interfering with the signal?

A: Yes, the Sennheiser EW 122P G4 has shielding which protects its internal components from RF interference.
