HeadRoom Micro DAC Owner's Manual

Congratulations on the purchase of one of the world's handiest audio products. Able
to buffer USB from your computer for low-jitter smoothness; able to strip S/PDIF digital
data from optical or coax inputs in a single fl ick of a switch; able to source a sweet
analog signal for your favorite headphone or speaker based back-end ...it's Super Micro
DAC! Okay, so we got a bit carried away, but so will you when your digital music so
wonderfully fi lls that space right between your ears.
Because they are functionally identical, both the Micro DAC and Ultra Micro DAC are
covered in this manual. The main difference between them is the asychronos sample
rate converter in the Ultra Micro DAC that increases the bit rate and depth to 192kHz/24
bit data and performs digital interpolation on the data prior to sending it to the D-to-A
converter. That's some long winded techno-speak for making your digital sources
sound smoother and more natural---more analog and vinyl-like due to smoother digital
data. There's one heck of an audio beast in that little Ultra Micro DAC enclosure.
Either way you go, you're getting the best DAC in Cirrus Logic's lineup; some of the fi n-
est metal-fi lm resistors and poly caps money can buy; and a perfectly lovely way to get
great sound without burning up valuable desktop real estate.
But enough of this chatter! Read on, hook up, and bliss out to your music. You deserve
