1. Line Output
The line out is the best sounding stereo-mini plug out there.
This is the signal source you plug into the input of your headphone amp. You
will need a mini-mini cable to plug from the Micro DAC into the Micro Amp or
other amplifier with a line input. HeadRoom sells various mini-mini cables;
we highly recommend one of varying lengths offered by Cardas. You can also
use this output to connect your Micro DAC to another amplifier, home stereo
receiver, or home theater system.
2. Optical Input
The optical input is the first of the digital inputs we’ll
discuss on the Micro DAC, and uses your typical Toslink connector. You get
this input signal from the optical output of your player. Not so many portable
audio players have optical outputs, but many portable DVD players and some
hard disk drive players do. Of course, you can get this signal from many pieces
of home equipment.
3. E/- 15VDC Power Input
Plug in your power supply here.
The ‘brick’ power supply is included with the Micro DAC; upon purchase you
will have chosen a voltage appropriate to your country’s voltage requirement,
either 110v (North America, Japan, Singapore and others) or 220v (Europe,
Australia, China, etc). We also recommend
the Astrodyne switching power
supply or the larger Desktop Power Supply (both accomodate any country’s
voltage requirement) as available power upgrades, these upgrades are par-
ticularly useful with the Micro DAC. Visit our website for more information
about these power supply upgrades.
4. Coaxial Input
The coaxial input is your typical coaxial connector. We rec-
ommend using a 75 ohm digital cable when using the coaxial input. Please
visit our website at headphone.com for various coaxial cables. If your Coaxial
cable is a standard size, you will need a mini adaptor that adapts a full size
coaxial connector to a mini size, they are available for purchase on HeadRoom
website, and are called RCA-Mini Mono adaptor.
5. USB Input
The USB input gets its signal from a computer: laptop, desk-
top, or Micro DAC-Mobile PC; PC, Mac, or Unix. Most computers will instantly
recognize the Micro DAC upon plugging it in, but occasionally some users may
need to go into the audio preferences and select the “USB Audio Codec” as
their primary sound device. You also may need to restart your music playing
program (iTunes, Windows Media Player, etc) once the Micro DAC is plugged
in.
