Professional 32-Bit Float Wireless Audio Recording

The Sony ECM-W5 supports 48 kHz/32-bit float recording, helping preserve quiet dialogue, sudden volume peaks, and natural vocal detail. Its wide dynamic range provides greater flexibility when adjusting recorded audio during editing, reducing the need for constant gain adjustments during production.

When connected to a compatible Sony camera, 32-bit float audio can be transmitted wirelessly and recorded directly alongside video. This streamlined recording workflow reduces separate audio file management and eliminates the need for manual audio synchronization in supported configurations.

For projects requiring high-resolution audio, the ECM-W5 also supports recording at up to 96 kHz/24-bit.

Dual Wireless Microphones with Expandable Four-Channel Recording

The ECM-W5 includes two compact wireless microphone transmitters, making it an effective solution for two-person interviews, presentations, podcasts, and video production.

For larger productions, the system supports up to four microphone transmitters by adding two optional Sony ECM-W5T units. When paired with a compatible camera, each microphone can be recorded on an individual audio channel for greater control during editing.

This expandable configuration is useful for panel discussions, multi-person interviews, corporate video production, and documentary filmmaking.

Stable Wireless Transmission Up to 500 Meters

Designed for professional recording environments, the Sony ECM-W5 offers stable, low-latency wireless transmission at distances up to 500 meters (1,640 feet) under line-of-sight conditions.

Its optimized wireless design uses Bluetooth-based frequency hopping to help minimize interference and audio dropouts, even in challenging radio environments.

The extended wireless operating range is particularly useful for outdoor interviews, event coverage, field reporting, and productions where the camera operator must remain separated from the subject.

64 GB Internal Recording and Audio Backup

Each ECM-W5 microphone transmitter features 64 GB of built-in storage, allowing audio to be recorded independently of the wireless receiver.

Internal recording provides an additional safeguard against wireless transmission interruptions and allows the microphones to function as portable standalone audio recorders.

Compatible Sony cameras also support simultaneous WAV audio backup recording, providing additional flexibility for post-production.

Recorded audio files can be transferred to a computer using a USB Type-C connection, either directly from the transmitter or through the charging case.

Sony MI Shoe Integration and USB-C Connectivity

The Sony ECM-W5 integrates with compatible Sony cameras through the Multi Interface (MI) Shoe, providing cable-free digital audio transfer and receiver power directly from the camera.

This reduces equipment clutter, simplifies camera setup, and enables recording without separate audio cables.

The included USB Type-C adapter also allows the system to connect with compatible smartphones and computers, extending its functionality beyond traditional camera recording.

The ECM-W5 can support mobile video production, computer-based podcast recording, online content creation, and standalone voice recording workflows.

Timecode Synchronization for Multi-Camera Production

The Sony ECM-W5 supports timecode synchronization to simplify the alignment of audio and video recordings during post-production.

With compatible Sony cameras, USB synchronization allows the microphone system to output a timecode signal that can be aligned with camera-recorded metadata.

This functionality is especially valuable for multi-camera interviews, professional filmmaking, event production, and projects requiring accurate synchronization across multiple recordings.

Wireless Audio Monitoring and Lavalier Microphone Support

The ECM-W5 receiver supports wireless audio monitoring through select Sony Bluetooth LE Audio-compatible headphones, allowing operators to monitor recorded sound without a traditional headphone cable.

Both the transmitter and receiver also feature a 3.5 mm external microphone input. This allows users to connect optional lavalier microphones, including the Sony ECM-L1, for discreet audio recording.

Additional audio controls include automatic or manual gain adjustment, noise reduction, and low-cut filtering to accommodate different recording environments.

Compact Design with Portable Charging Case

The Sony ECM-W5 is designed for fast setup and mobile production. Opening the charging case activates the system, and removing the microphones and receiver prepares them for recording.

Each microphone transmitter offers up to 7 hours of continuous operation on a full charge. The charging case extends total transmitter operating time to approximately 11 hours.

When connected to a compatible Sony camera through the MI Shoe, the receiver can draw power directly from the camera, reducing dependence on its internal battery.

The compact transmitters support clip and magnetic mounting, making them suitable for discreet placement on clothing or handheld use during interviews and live reporting.
