The DAC204 is a multi-format digital-to-analogue and digital-to-digital converter. Its many input and output options make it equally useful for use in a professional mixing or mastering studio as for an audiophile-grade listening room.

The DAC204 accepts incoming digital audio streams straight from any USB-equipped computer, tablet, or mobile phone. It can also receive S/PDIF and AES/EBU audio via its S/PDIF or Toslink connectors.

The DAC204 converts the incoming digital streams to analogue audio, which simultaneously appears on its balanced XLR connectors and unbalanced RCA connectors. 

It can also perform digital-to-digital conversion and output digital audio in AES/EBU or S/PDIF formats through the corresponding connectors and a BNC output connector.

Should the incoming audio be in DSD format, the DAC204 can convert that to PCM.

The DAC204 can be permanently connected to multiple digital units, and the user can easily switch between them with the front-mounted Input Selector switch.

The DAC204 is the bigger sibling to the DAC205. The two units offer the same conversion quality, but the DAC204 has a USB input and can convert DSD to PCM audio. 

The DAC204 and DAC205 are relatively affordable options to Weiss Engineering’s higher-grade units such as the DAC501and the HELIOS. They do not have the onboard digital processing capabilities of those units, nor do they include headphone outputs or remote controls.
