The ECM-W2BT wireless microphone is compatible with select Sony cameras that have a Multi-interface shoe. The ECM-W2BT wireless microphone takes the digital audio signal output from the receiver and passes it through the MI shoe so there is no need for additional cables or power.

Nobody actually knows what cameras are compatible with the ECM-W2BT. If you click on the link for compatible cameras you get the image that is shown above. I am not sure how you can release a product and not know what cameras it works with.

According to Sony, the ECM-W2BT has been completely redesigned for high sound quality using an advanced omni-directional mic capsule to capture clear sound recordings from any direction.

Sony also claims that the ECM- offers increased stability of the wireless connection between microphone and receiver, even with obstacles or in crowded environments with high wireless activity. The claimed operating range is up to 200m (656 ft) line of sight.

The ECM-W2BT offers three sound pick up modes:

  • MIC mode
  • MIX mode
  • RCVR mode

MIC mode will only pick up audio from the microphone transmitter. RCVR mode only picks up sound from the internal microphone on the receiver, so the user can record audio of themselves. MIX mode picks up both transmitter and receiver audio which is useful when audio from both the subject and the user is desired.

The ECM-W2BT mic supports stereo audio input and an external 3.5mm stereo mini-jack to allow for stereo sound pickup, so it can be used in combination with the stereo-capable lavalier microphone such as the ECM-LV1 compact stereo lavalier microphone. The receiver is equipped with a 3.5mm audio output. The ECM-W2BT can be used with non-Multi-Interface shoe model cameras.

When longer operation is needed, there is a battery assist function via the power supply from the camera’s Multi Interface shoe enables the user to operate the receiver for up to 9 hours

The ECM-W2BT wireless microphone includes an attenuator function. You can select one of three attenuator levels. The ECM-W2BT also includes a windscreen.

The ECM-W2BT includes a LINK lamp to notify the user of the status of the communication between the microphone and the receiver and a POWER lamp to show you the remaining battery charge.
