Connecting Your Deckard
If you're using the Deckard in digital input mode, connect its
USB input to your computer or other USB-equipped source
and ensure the input switch on the front panel is set to "USB".
In the event you want to use the Deckard in analog mode, you
can connect the source to the left and right RCA analog inputs
and change the input switch on the front panel to "RCA". To
use the Deckard as a system preamplifier use the pair of left
and right RCA outputs on the rear panel labeled "OUTPUT";
just add powered speakers and you've got a desktop audio
system ready to go.
The internal DAC has impressive specifications that plays 16 to
32-bit audio and sampling rates from 44.1kHz to 384kHz on
Mac OS 10.6.4 and above. Windows computers are system
limited to 192kHz and 24-bits. The front-panel gain switch
chooses between three gain settings and we recommend
starting at the uppermost position labeled Mid with Audeze
headphones; other brands may require changing the gain.
The headphone output is a standard quarter-inch stereo jack
with RCA line-level analog inputs and outputs.
