The Sennheiser EW 122P 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 122P 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 an ME 4 cardioid 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 in noisy environments, for projects ranging from documentaries to wedding videos, corporate spots, and hands-free interviews.

The EW 122P 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 122P G4 features rugged, all-metal chassis well suited for extended use on location. The lightweight and compact bodypack transmitter is easy to conceal. Its rounded edges are soft to the touch making it comfortable to wear for the talent. A locking connector ensures that your lav doesn’t detach at a critical moment, while a convenient switch allows you to mute your mic.

Q: 8. I currently own the Sennheiser XSW-D lav set and need to upgrade to a system that will allow two mics simultaneously. Will this receiver allow more than one mic at a time and if so will my existing transmitter work with this receiver?

A: No, the Sennheiser EK 100 G4 Camera-Mount Wireless Receiver included with the Sennheiser EW 122P G4 Camera-Mount Wireless Cardioid Lavalier Microphone System is single-channel and can only be used with one transmitter. Sennheiser does offer any camera-mountable receivers or other EW Series wireless receivers with two channels. You will need to get a second receiver in order to use two transmitters at the same time. If you need to use two mics and have a camera with a single mic input like a DSLR or mirrorless camera, you can use a passive mini mixer such as the Kopul CMX-1-V2 Two-Channel Mini Mixer with Shoe Bracket (B&H # KOCMX1V2) or the Kopul CMCS-1 Passive 3.5mm Microphone Combiner/Splitter (B&H # KOCMCS1) to connect the output from each receiver and then send one signal with the audio from both mics into the camera.

Q: 9. I have this item, is there any way to use this wired? That is, to avoid the need to use batteries for non-moving, studio usage, drawing power from a mixing table for example?

Q: 10. Can the system be used with a zoom recorder?

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