Description
The
USB-AES Matchbox is a professional
digital audio interface and digital-to-analog
converter. The unit provides AES/EBU digital audio
input and output from any computer that supports
USB. The USB-AES Matchbox is ideal for broadcast
stations, commercial sound, and any application
where AES/EBU digital audio needs to interface
with a computer. The USB-AES Matchbox is USB powered.
The
USB-AES Matchbox connects to the computer via
a USB port. Any O/S that supports USB 1.1 or higher
can be used; no special driver or software is
needed. The unit provides AES/EBU professional
digital audio input and output via XLR connectors.
Sample rates of 48.0, 44.1, and 32.0 kHz are supported
with 16 bit resolution. The AES/EBU input and
output are balanced and transformer isolated,
providing galvanic isolation to eliminate any
chance of hum or noise caused by ground loops.
Auxiliary S/PDIF unbalanced digital I/O allows
use with consumer digital equipment.
The
USB-AES Matchbox also provides professional analog
line level outputs on XLR connectors. The analog
output, utilizing a Burr-Brown 8X oversampled
D/A converter and advanced filtering technology,
produces stellar performance that outperforms
virtually any sound card and often surpasses the
audio quality of many 24 bit systems. The analog
output levels are adjustable with Output Level
trimmers recessed behind the front panel. The
internal switch-mode 30-volt supply ensures 20db
of headroom above normal operating level.
Other
useful features include Output Confirm LEDs that
indicate the presence of output audio, and a Speaker
output for use with amplified monitor speakers.
The Speaker output can be muted with an external
contact closure via the Mute port. The steel chassis
provides effective RF and EMI shielding. The unit
is compliant with the most recent AES grounding
standard.
The
USB-AES Matchbox is 1/3 rack width, and can be
rack-mounted using the optional rack-mount shelf,
or cabinet or wall mounted using optional wall
mounting brackets.
