The ECM-AW4 Bluetooth Wireless Microphone System from Sony is a complete battery-powered Bluetooth wireless microphone system. It plugs into virtually any kind of video camera, DSLR, or recording device that features a 3.5mm mini-jack microphone input. The transmitter has a built-in mic, or you can use a separately available external mic with 3.5mm output (Plugin Power supported). Receiver unit has a talk-back function that allows the camera operator to communicate clearly with the subject. The mic has a range of up to 150 feet.

This mic system allows a subject and a device operator to communicate, eliminating the need for a separate intercom system. In this way the camera operator can act as a director, giving direction or suggesting interview questions to the onscreen talent, even if they are out of ear shot. A 3.5mm headphone jack/audio output is provided on both the transmitter and the receiver to facilitate this feature.

For mounting or wearing the microphone and receiver, a belt clip and an arm band are included. The arm band enables you to attach the transmitter to a subject that is wearing clothing that cannot accommodate a belt clip. An included carrying pouch will help to protect the transmitter.

Wide Compatibility

Compatible with nearly any video camera or portable audio recorder with a 3.5mm mini-jack microphone input

Two Way Communication

From up to 150 feet line-of-sight away from the camcorder, you can shoot while recording whole conversations with each other

One Way Communication

Select to pick-up only the voice of the subject, or both the subject's and the camera operator's voices

Separate Earphones

Two separate earphones are provided for both the microphone and the receiver units

Up to Three Hour Battery Life

In standby the microphone battery lasts up to nine hour and the receiver battery up to three hours

question

Can you use multiple (+4) SonyECM-AW4 Bluetooth Wireless Microphone System in same room?
Asked by: Donald H.
I have only used one paired set and in such can't answer this question for using 4.However, my advise is to have sender and receiver facing each other for good quality. If the body conceals the microphone set quality deteriorates significantly.Best have it fixed under your dress, but facing the camera/receiver.

question

Can someone suggest a way(s) to monitor the db level when the system is in use? I have found that the volume has been accidentally turned down and did not realize it until editing the video later.
Asked by: Anonymous
The receiver has a headphone/monitor jack in addition to the output jack, it won't tell you dBs, but you can at least listen for high/low levels.

If I use a splitter and connect 3 or 4 of these, will there be phase alignment issues and sound weird?
Asked by: Anonymous
Hmm...how would that work? As far as I know, there's a fixed relationship between the mic and the receiver- where would you add the splitter?
