Sony has launched the ECM-W2BT wireless microphone, along with the ECM-LV1 lavalier microphone , designed for Sony mirrorless cameras with a Multi Interface (MI) Shoe on the camera head (but still supports a normal 3.5mm).
The ECM-W2BT is a wireless mic that supports Digital Audio Interface via Multi Interface or MI Shoe on many Sony camera heads, meaning that this mic can transmit audio directly to the camera. There is no need to plug in a separate cable, there is also a 3.5mm audio output port for use with other camp cameras.
For specifications, it can transmit signals up to 200 meters with Qualcomm’s aptX Low Latency codec technology. The battery is built-in, charges via the micro USB port and when connected to the MI shoe on the camera head can be used for up to 9 hours.
The ECM-W2BT has three modes:
MIC mode only records sound from a microphone transmitter.
MIX mode records audio from both transmitter and receiver.
RCVR mode only records audio from the receiver attached to the Digital Multi Interface shoe port.
Other features include a LINK light that contacts when the receiver is connected to the transmitter, a built-in attenuator function, or an audio attenuator with three levels to adjust the sound to a low volume or to adjust the volume low. Down It also comes with a windscreen to protect the wind in the box.
For those of you who want a separate mic, the ECM-W2BT also supports stereo audio input via the 3.5mm port, a perfect match to the tiny ECM-LV1 lavalier mic it launched together. The clip can rotate 360 degrees, comes with a windscreen for windproof as well.
