Product description

• Sennheiser AVX-Combo SET Digital Camera-Mount Wireless Combo Microphone System (1.9 GHz)
  • Sennheiser AVX Digital Wireless Audio System: Hands-On Review
  The ultra-compact Sennheiser AVX-Combo SET provides professional videographers, video journalists, or vloggers with a dependable wireless microphone system that's so easy to use, it's like having a dedicated sound engineer on set handling audio tasks.Made with simplicity in mind, but without compromising audio quality, this self-configuring digital system handles time-consuming frequency setup and mic-level adjustments for you, so you're ready to shoot within seconds. Now, you can focus on the other critical elements vying for your attention during a shoot, and confidently record crisp, clear audio on your camcorder, DSLR, or mirrorless camera.This combo set offers a flexible solution by including a bodypack transmitter, an ME 2-II omnidirectional lavalier mic, and a handheld transmitter equipped with an MMD 42 omnidirectional capsule. The lav provides a discreet hands-free mic option, while the handheld reporter mic features enhanced wind reduction and a wide, forgiving pickup pattern that delivers intelligible speech, even when the mic is moving between speakers. The system is ideal for wedding and corporate videos, documentaries, or outdoor interviews.It should be noted that while this system includes two microphones, only one can be used at a time.

  It Goes Where You Go

  • • The lightweight AVX system is easy to carry with you when every ounce counts.
    • The roadworthy bodypack transmitter features a rugged metal chassis with a form factor even smaller than the EW G4. A locking connector ensures that your lav doesn’t detach at a critical moment, while a convenient switch allows you to mute your mic. The display shows battery life and signal strength.
    • The robust handheld transmitter also features a rugged metal chassis and a display that shows battery life and signal strength.
    • The discreet receiver plugs directly into the XLR input of your camcorder and rotates 320° to get out of the way of lights or other accessories you may have mounted on your camera. An AF button on the receiver allows you to adjust the output level to your camera, if necessary. In addition, the receiver comes with a shoe mount and 3.5mm output cable, making it a great fit for DSLR and mirrorless shooters.

  Setup Made Simple

  Automatically Finds a Clean Channel
  • • The digital AVX automatically finds the cleanest frequency in the 1.9 GHz band as soon as you power up the receiver.
  Fast Pairing
  • • A long press of the Pair button on both receiver and transmitter links the two devices. Once the indicator LED turns green, you’re good to go.
    (Note that the AVX is a peer-to-peer system, meaning the transmitter can only be paired with one receiver).

  Clear and Natural Speech

  • • The ever-popular ME 2-II omnidirectional lavalier microphone 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.
    • The handheld transmitter features an interchangeable MMD 42 dynamic omnidirectional capsule that minimizes handling and wind noise to deliver a clear sound in live reporting and broadcasting environments.
    • If you are working on a trade-show floor, busy street, or at a sporting event, you can swap out the included omni capsule with an MMD 835 cardioid capsule (available separately), that's better suited for noisy environments.
    • The AVX's automatic mic-level control takes full advantage of the system's wide dynamic range to deliver consistent speech without clipping and distortion, even when your talent goes from a whisper to a shout.
    • The system delivers 24-bit/48 kHz audio with an extended 20 Hz to 20 kHz frequency response, for pristine, nuanced recordings.

  Protected Wireless Transmission

  • • The AVX operates in the license-free 1.9 GHz band—away from TV and Wi-Fi interference—to create a wireless peer-to-peer connection, for clean audio without dropouts at a range up to 98’.
    • The system automatically finds the cleanest frequency, free from RF interference.
    • If interference is detected, the AVX automatically increases the power on the transmitter—up to 250 mW—to overcome the problem.
    • If the increase in power isn’t sufficient, the system substitutes a clear frequency well before the audio signal itself is affected, for clean, worry-free sound.

  Smart Power Management

  • • The AVX transmitters and receiver feature removable, lithium-ion batteries that are recharged via the USB port.
    • The transmitters give you up to 15 hours of battery life, while the receiver is limited to 4 hours.
    • The receiver turns itself on and off when it senses phantom power from your camcorder, extending battery life in the field.
    • All three components can also be powered through their USB ports allowing them to run for numerous hours on a USB power pack or indefinitely if you have access to AC.
    • The included BA 30 battery for the bodypack transmitter, BA 10 for the handheld transmitter, and BA 20 for the receiver are also available separately, so you can have fully charged spare batteries ready in the field.

  Other Features

  • • Up to eight AVX systems can operate simultaneously in the same area
    • AES 256-bit encryption for secure communication
    • Made in Germany
