The Sennheiser EW 135P G4 Wireless Microphone System 470-516 MHzcamera-mount wireless handheld 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 135P 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 transmitter offers an interchangeable capsule design, allowing you to swap mic capsules with different polar patterns to suit your application.

The system includes a camera-mount receiver and an updated, lightweight handheld transmitter equipped with an MMD 835 cardioid capsule—ideal in situations where you don't have time to position a lavalier mic or you need to quickly pass the mic between several people. The receiver connects to a camcorder or a DSLR/mirrorless camera to capture crisp-sounding speech or dialog for projects ranging from wedding and corporate videos to red-carpet and man-on-the-street interviews in noisy environments.

The EW 135P 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.

Q: 3. I've read that the AVX series introduces a 19 ms delay. Does this system introduce any delay? I will sometimes want to run wireless and wired microphones at the same time.

A: Hi Dave - the evolution Wireless series is an analog wireless system that operates on UHF frequencies - there's no delay with respect to transmission time. However, the distance of your wired microphone capsule from your wireless lav capsule should also be taken into consideration - due to timing differences between direct audio and distant audio, you can get a phasing sound, making your audio a bit hollow or lacking body. The AVX system operates on a DECT Wireless standard, which has 19ms of delay - we generally recommend to not mix G4 and AVX wireless together for that reason.

Q: 4. Can we use two of the same models with the same frequency range at one time or do we need two different frequency systems? Basically, can we use two of the same exact transmitter/receivers simultaneously?
