The Sennheiser EW 112P G4 camera-mount wireless lavalier microphone system features the proven combination of reliability, flexible control, and broadcast-quality sound that has made the EW Series an industry standard for videographers, journalists, and content creators all over the world.

The EW 112P G4 gives you the tools to adapt and meet the wireless challenges that inevitably arise on set. The frequency scan function automatically searches for the cleanest frequency at your location, while the adjustable input sensitivity on the transmitter accommodates mic levels ranging from booming voices to quiet speech, and even line-level audio.

The system includes the improved ME 2-II omnidirectional lavalier mic, a bodypack transmitter, and a camera-mount receiver. It connects to a camcorder or a DSLR/mirrorless camera to capture crisp-sounding speech or dialog for projects ranging from documentaries to wedding videos, corporate spots, and hands-free interviews.

The EW 112P G4 is backward-compatible with previous evolution systems, giving you the ability to mix and match G4/G3/G2/G1 receivers or bodypack, handheld, and plug-on transmitters. It is also compatible with EW 500 systems.

• The EW 112P G4 features rugged, all-metal chassis well suited for extended use on location. The lightweight, compact bodypack transmitter is easy to conceal and offers rounded edges that are soft to the touch and comfortable for the talent to wear. A locking connector ensures that your lav doesn’t detach at a critical moment, while a convenient switch allows you to mute your mic.
• Using the included shoemount adapter, the equally compact receiver easily mounts on your camera without adding much weight. The included cables allow you to connect the receiver to the 3.5mm or XLR audio input of any DSLR/mirrorless, camcorder, or recording device.
• Both transmitter and receiver feature daylight-readable LED displays showing reception quality, battery status, and audio level. To get you going quickly, they synchronize via infrared interface with the simple push of a button.

• The EW 112P G4 ships with the popular ME 2-II omnidirectional lavalier microphone, which delivers a natural sound optimized for speech intelligibility. Its omnidirectional polar pattern ensures that the sound remains consistent, even when the speaker's head moves away from the mic.
• To take full advantage of the ME 2-II’s dynamic range, the system employs proprietary HDX compander technology, preserving your sound without adding unwanted noise during transmission, and delivering audio with remarkable accuracy and quality.

Related Questions and Answers

Q: 1. What frequency is best for Qatar ( Middle East )

A: According to page 49 on the follwing page from Qatar's Frequency Allocation Table, frequencies for broadcasting wireless mics are allocated to 470 - 790 Mhz. Based on this, you can use any of the 3 frequency bands that the Sennheiser G4 system has to offer without any issues. https://www.motc.gov.qa/sites/default/files/qatar_national_frequency_allocation_table_qnfat_0.pdf

Q: 2. Can these lavalier be wirelessly connected to a soundboard?

A: Yes. The Sennheiser EW 112P G4 Camera-Mount Wireless Omni Lavalier Microphone System can be connected to a soundboard (mixer). The system comes with two receiver output cables, one with a 3.5mm connector and one with an XLR connector. You can use the cable with the XLR connector to send the output from the receiver into a mic input on the board.

Q: 3. 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: 4. Will this work with canon c200?

A: This wireless system would work well with the Canon C200 camera. The appropriate XLR output cable for the receiver is supplied as well as mounting hardware to affix it to your camera's cold shoe. You can choose to come into the camera at mic or line level.

Q: 5. 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: 6. 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: 7. are these still legal in the US? Here's what the FCC says about frequencies - Unlicensed wireless microphone use is permitted on the 902-928 MHz band, the 1920-1930 MHz, and on portions of the 2.4 GHz and 5 GHz bands under specified power levels and rules for operation for each of those bands.

A: These are legal in The US without a liscence. The FCC currently allows wireless microphones in the range of 470-608Mhz to opperate.

Q: 8. 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?

Q: 10. Which frequency would be best for Hawaii (specifically the North Shore of Oahu)? I see some frequencies aren't allowed in Hawaii? Maybe? A specific frequency would be appreciated.

A: There is no one frequency that is best to use all of the time. Any of the bands offered will work throughout Hawaii. The reason there are three bands is so that you can use many systems in the same space and at the same time. The receiver will scan for the best available frequency within that band to use at that time. You can use up to around 8 systems in the same band, in the same space and at the same time, before you would need to worry about switching bands for your next group of systems, to avoid interference with your first group of system.
