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.

Q: 1. What is antenna diversity? I'm looking for what I call "true" diversity - multiple receive antennas.

A: "If you glance at the Sennheiser EK 100 receiver, you only see one antenna. However, if you write it off as a non-diversity system, you are mistaken. The EK 100 features a technology called “adaptive diversity,” which utilizes the connected output cable as the second antenna, making it a diversity receiver. By using the ground connection of its output as the link to a second antenna, it provides improved reception and reliability" Taken from "Understanding the Basics of Sennheiser G3 Camera-Mount Wireless Systems" https://www.bhphotovideo.com/explora/pro-audio/hands-on-review/understanding-the-basics-of-sennheiser-g3-camera-mount-wireless-systems.

Q: 3. Are these legal in the us? Here's what the FCC says about frequency ranges. 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: Yes all frequencies between 470-608MHz are legal in the US

Q: 4. Does it work with iPhone camera?

A: This wireless system can be used as an external microphone when shooting video with your iPhone's camera, by connecting the included cable from the receiver to following adapters: Rode SC4 3.5mm TRS Female to 3.5mm Right-Angle TRRS Male Adapter Cable for Smartphones, BH #ROSC4 and the Apple Lightning to 3.5mm Headphone Jack Adapter, BH #APLAADAP.

Q: 5. Can the system be used with a zoom recorder?

A: Yes. Absolutely. I recommend using the XLR output connector to go into the Zoom .

Q: 6. Hi, just bought two of these. When I plug them into the separate XLR channels on my Sony fs7, there is a noticeable hiss being recorded. When I only plug in one, the hiss goes away. Any suggestions? Thanks. Each is set to a different frequency.

A: Try each channel individually to see if there is a noise floor isolated to one channel. I would also recommend double checking that the level from each system is as close to the same as possible.

Q: 7. Hi, I was hoping to know what the best frequency range for New York City would be?

A: NYC is a very flooded market with something on every frequency. The frequency bank you choose will not matter as much as making sure you do a scan at every new location you go to.

Q: 8. Can you buy an additional transmitter and sync it to record two subjects direct to camera? Or do you need to purchase two units?

A: Short answer is no you can not, you will need an additional system if you want to record two subjects. You can send one transmitter to multiple receivers, but not the other way around. One receiver cannot receive signals of two transmitters. There are only a few select systems on the market that have a dual receiver built into one body.

Q: 9. Kind of 2 questions: Whats the difference between the frequency models? It shows A, A1, & G with different frequency ranges. Which is best?

A: The frequencies have nothing to do with range. The range on all these is about 300'.It really doesn't matter you can pick whatever frequency block you want. You can run as many as 4 or more units in the same frequency block. When you reach a maximum of let's say 4 units in the same block. Then the next unit you would need to change blocks. So 4 A's then switch to A1 for the next 4. So it only matters when you are running several units at the same time.

Q: 10. Will it work with DSLR cameras (specifically a Canon 7D)?

A: Yes. You need to run the receiver into the camera via a 3.5 mm jack.
