IntroducIng THE BDA-1 EXTERNAL DAC
STATE-OF-THE-ART
The Bryston BDA-1 is a state-of-the-art external
Stereo DAC (digital to analog converter) using fully
discrete Class-A proprietary Bryston analog circuits,
two independent linear power supplies and dual Crystal
CS-4398 DAC chips. The BDA-1 features an impressive
array of inputs for USB, COAX, OPTICAL, AES-EBU
and BNC equipped digital devices. For audio outputs, the
BDA-1 offers both balanced XLR as well as unbalanced
RCA stereo connectors on the rear panel. The BDA-1 is
RS-232 software upgradeable, making it the most flexible
high performance DAC on the market.
BDA-1 FEATURES:
• Dual 192K/24Bit Crystal DAC’s
• Independent dual power supplies
• Discrete Class A analog output stage
• Oversampling
• Synchronous upsampling (176.4K/192K)
• Selectable upsampling feature
• Independent analog and digital signal paths
• Inputs: USB (1), COAX (2), OPTICAL (2),
AES-EBU (1) BNC (2)
• 32, 44.1, 48, 88.2, 96, 176, 192K sampling

music servers
• Cosmetically matches Bryston C-Series BP26/
MPS2/BCD-1
JITTER REDUCTION
Jitter is a mistiming of data being moved from point A to
point B in any synchronous digital system. Think of jitter
as individual ticks on a clock—however each tick is not
occurring at exact one-second intervals. Some are slightly
less than a second and some are slightly longer, and they
average out so that no actual time is being gained or lost over
a large number of seconds. Jitter is the difference between the
shortest and the longest second, and in digital audio systems
this specification is usually measured in nanoseconds.
Both the frequency and the jitter characteristics of the
system’s digital clock will affect the accuracy of reproduction.
The frequency, if not accurate, can cause the pitch and speed
of the music to change, and in some systems cause drop-outs
if there is no data available.
