DAC2 AUDIO CONVERTER
e DAC2 is a high-performance stereo D/A converter with a wide
variety of user selectable digital inputs. It has evolved from EMM Labs
acclaimed converter systems which are used worldwide in professional
studios to create some of the nest recordings.
e DAC2 provides conversion from a wide variety of digital input
formats, including USB Audio for computers, media systems and
digital audio playback machines making it an extremely exible
converter system that can act as a standalone conversion hub to a host
of digital sources.

• EMM Labs proprietary internal MDAT algorithm to up-sample
and condition digital audio to twice the SACD/DSD sample
rate.
• Ed Meitner’s proprietary discrete Dual Differential DAC circuit.
• Uses our exclusive aerospace grade composite laminate circuit
boards.
e DAC2, when paired with an EMM Labs transport, performs as an
unparalleled CD/SACD playback system.
