UAC-232 overview

High-quality audio inputs

Using original dual A/D converter circuits and 32-bit float recording technologies with a maximum sample rate of 192 kHz, the UAC-232 can process input signals as super-high-resolution audio without any need for gain adjustments.

Audio input with no need for gain adjustment

Dual A/D converter circuits enable recording sound ranging from quiet to loud without making gain adjustments.

Editing in DAWs and other software

Since 32-bit Float WAV file format is used for recording, the recording audio quality is retained when editing.

Dual A/D converter circuit overview

The UAC-232 has two A/D converters with different input gains for each input circuit. This design enables high-quality audio recording with a DAW, for example, without the need to adjust input gain settings, a step that is normally indispensable.

Providing amazing dynamic range

By combining two A/D converters, a wide dynamic range not possible with a single A/D converter has been realized.

Switching between two A/D converters

The UAC-232 constantly monitors data from the two A/D converters, and automatically selects the one that provides the best recording results.

32-bit float WAV file overview

32-bit float WAV files have the following advantages over conventional 16/24-bit linear WAV files.

These features enable the quality of the sound during recording to be maintained when editing in DAWs and other software.

Resolution advantage

32-bit float WAV files have the advantage of being able to maintain high resolution even at low volumes. As a result, quiet sounds can be made louder when editing after recording without degrading their quality.


*■ 16/24-bit linear WAV*
	Volume raised		Resolution is low


*■ 32-bit float WAV*
	Volume raised		Resolution is high

Clipping advantage

If a waveform sounds clipped when output from the UAC-232 or in a DAW, it can be edited after recording to lower its volume and restore an unclipped waveform because the data in the 32-bit float WAV file itself is not clipped.


*■ 16/24-bit linear WAV*
Clipped recording	Volume lowered	Still clipped


*■ 32-bit float WAV*
Clipped recording	Volume lowered	Not clipped
