Sony XLR-A4 XLR Adapter

The Sony XLR-A4 XLR Adapter is a professional audio interface designed for the Sony a7R VI and compatible Sony cameras, delivering high-quality multi-channel audio capture for filmmaking, interviews, documentaries, livestreaming, and professional content production.

Engineered for advanced audio workflows, the adapter supports 96 kHz sampling and 32-bit float recording, enabling exceptional dynamic range and highly detailed sound capture while helping reduce the risk of clipped audio in unpredictable recording environments.

The XLR-A4 features two combo XLR-1/4″ inputs along with an additional 3.5mm microphone input, providing flexible compatibility with professional microphones, wireless receivers, mixers, and line-level audio sources.

Built with dual analog-to-digital converters (ADCs) and supporting four-channel audio input, the adapter allows creators to record multiple audio sources simultaneously with enhanced clarity and precision for professional post-production workflows.

Designed for seamless integration with Sony cameras, the unit mounts securely via the Multi Interface Shoe, enabling direct digital audio transfer without additional cables while maintaining a clean and compact rig setup.

For improved workflow management, the adapter supports separate WAV file in-camera recording, helping preserve high-quality isolated audio tracks for editing and sound mixing.

An integrated microphone holder provides convenient mounting support for shotgun microphones and other compatible audio accessories, making the system ideal for run-and-gun production environments.

Compact, professional, and production-ready, the Sony XLR-A4 XLR Adapter is an excellent solution for creators seeking broadcast-quality audio capture, flexible multi-input recording, and advanced professional audio control for Sony mirrorless camera systems.

Product Features in Detail

96 kHz sampling 1 for detailed audio
Ambient textures and subtle vocal nuances are captured at up to a 96 kHz sampling rate for detailed recording that maximizes the performance of professional microphones. With a Hi-Res Audio-compatible microphone2, frequencies beyond 20 kHz can also be captured, expanding post-production flexibility and adding depth and realism to your work.  [1] 48 kHz  [2] 96 kHz

32 bit float1 for flexible post-production
32 bit float recording on compatible cameras1 provides wide dynamic range and greatly reduced risk of clipping when levels are adjusted during editing. This makes post-production workflows more flexible and reduces the need for precise gain adjustments during recording3.  [1] Speaking voice recording  [2] Sudden loud sound recording

Dual ADCs4 for wide dynamic range
To maximize the performance of high-quality microphones, dual ADCs combining two analog-digital converters (ADCs) operating at different gain levels are employed, faithfully reproducing a wide dynamic range from extremely quiet to loud input sounds. With the dual ADC-equipped XLR Adaptor, the captured audio is converted into 32 bit float digital data, preserving the full dynamic range and enabling greater flexibility in post-production without precise gain adjustments during recording.

4-channel audio input5
Supports 4-channel audio input5, allowing simultaneous multi-microphone recording to independent tracks for flexible editing. Safety channels with different gain settings and flexible input assignment to CH1–CH4 provide greater confidence and creative control.

Convenience of Sony's ecosystem
Simply attach the XLR Adaptor to the Multi Interface (MI) Shoe™ of a compatible camera5 to enable cable- and battery-free power and audio connections. Support for Hi-Res Audio microphones and 96 kHz / 32 bit float recording delivers high-quality, edit-resilient sound with independent 32 bit float WAV recording.

Intuitive operation
A high-visibility layout improves operability, with OL (overload) lamps on each input for instant level monitoring. LOW CUT and ATT (attenuator) switches and manual gain dials are grouped on one side, enabling flexible and intuitive setup for each output channel.

Shoe Audio Extension Cable (supplied)
The supplied Shoe Audio Extension Cable provides flexible mounting options. Even when used with a rig, it enables adaptable installation to achieve an optimal layout for different shooting environments.

High durability for professional use
A low-profile, reinforced design ensures high durability for on-location use, while a low center of gravity reduces stress on the Multi Interface (MI) Shoe. When used with the supplied Shoe Audio Extension Cable Reinforcement Attachment, stable and reliable mounting is maintained even during extended operation.

Support for USB audio output
The built-in USB Type-C® port6 connects directly to a PC for camera-free applications such as studio recording and audio podcasting. The supplied Mini-Stand provides stability and flexibility.

Supplied accessories7
The XLR Adaptor comes with a set of useful accessories including [1] Case, [2] Mini-stand, [3] Shoe Audio Extension Cable Reinforcement Attachment along with [4] Shoe Audio Extension Cable itself, and two [5] Connector protector caps.

Environmentally conscious
Sony's environmental plan "Road to Zero"8 aims for a zero environmental footprint by 2050. The XLR Adaptor uses recycled plastic materials, constituting more than 22%9 of the main unit's plastic weight, including our durable SORPLAS™ material. We are also transitioning to non-plastic packaging materials10.
