Sony ECM-W5 Wireless Mic System Records 32-Bit Float for $399.99

Sony has announced the ECM-W5, a wireless microphone system made up of two transmitters with built-in microphones, one receiver and a charging case. It works with Sony cameras that have a digital Multi Interface (MI) Shoe and, through a supplied USB-C adapter, with phones and computers. The kit is available for preorder at $399.99 and is scheduled to ship on November 19.

Recording and transmission

The system uses digital Bluetooth frequency hopping and reaches up to 500 m (1,640 feet) line of sight, with low latency for uses such as live streaming. Each transmitter stores backup audio on 64GB of internal memory: about 90 hours at 48kHz/32-bit float or 60 hours at 96kHz/24-bit. Files can be copied to a PC over USB-C from the mic or through the case. Through the MI Shoe, 32-bit float audio is written into the camera's video file.

• Four-channel digital output; two extra ECM-W5T transmitters can be added for four speakers on separate tracks
• Omnidirectional capsule, 21 dB SPL self-noise, 124 dB maximum SPL
• Auto gain or manual gain from -12 to +12 dB, with switchable noise cut and low cut
• 3.5mm input for lavaliers such as the ECM-L1
• Timecode sync via USB SYNC mode with compatible cameras

Monitoring, controls and power

Compatible Sony wireless headphones can be used for cable-free monitoring through Bluetooth LE Audio, and their own microphone can also feed the receiver. The receiver has an AMOLED touchscreen and a control wheel. Units power on when taken out of the case, and with camera-linked power the MI Shoe can switch on the receiver and mics. Each transmitter and the standalone receiver run up to seven hours per charge, or about 11 hours with the case. The receiver weighs 35 g and each transmitter 27.1 g.
