What does the XLR-A4 Digital XLR Adaptor Kit do?

The XLR-A4 lets you connect XLR microphones to a compatible Alpha camera and capture high-quality audio within the Sony ecosystem. It supports 96kHz / 32bit float recording that handles everything from whispers to sudden loud sounds while reducing the need for gain adjustments.

Why is 32bit float recording useful with the XLR-A4?

32bit float recording captures a wide dynamic range and greatly reduces the risk of clipping, so you can adjust levels extensively in post-production while maximizing flexibility. It handles everything from whispers to sudden loud sounds.

Does the XLR-A4 require setting precise gain levels on location?

Because the signal is captured as 32bit float using dual ADCs, you don't need to dial in gain as precisely during recording. The adapter is designed to handle everything from whispers to sudden loud sounds while maintaining usable headroom.

How do the dual ADCs on the XLR-A4 work?

The XLR-A4 uses dual analog-to-digital converters to preserve a wide dynamic range. Dual ADCs are enabled when the unit is connected to a camera that supports 96kHz/32bit float, or when used as a USB audio interface.
