DEVICE SUMMARY

Device Capabilities
A2-7300 Series
units are high quality audio format converters designed primarily to
provide maximum format flexibility for the C2-7310 HD Audio/Video Processor's
audio inputs and outputs. The C2-7310 provides AES3-id audio I/O via two HD-44
Connectors. Any two of the A2-7300 models, or two of the same model, can connect
to these connectors to bring the AES3-id signals out to BNC connectors or to change
the audio format completely. All of the AES audio channels can be synchronized to a
DARS reference when connected to the C2-7310 via any of the A2-7300 units.
Additionally, the A2-7300 units may be used in conjunction with one another, without
the C2-7310, to provide bi-directional analog/digital or AES3/AES3-id conversion.

Device Features
A2-7302
provides an HD-44 interface to 16 AES (8-in/8-out) on XLR connectors and
a DARS reference input on a BNC connector. This unit contains eight balanced AES
to AES3-id converters, plus eight AES3-id to balanced AES converters to provide
AES I/O.
A2-7312
provides an HD-44 interface to 16 AES3-id (8-in/8-out) and a DARS
reference input on BNCs mounted on a 1RU panel via a 1.5 meter (4.5') interconnect
cable. The connectors may be separated from the panel if system wiring
requirements dictate.
A2-7322
provides an HD-44 to 16 Analog Stereo (8 -in/8-out), balanced or
unbalanced, on terminals and a DARS reference input on a BNC connector. This unit
contains eight high quality stereo analog to AES3-id converters, plus eight high
quality AES3-id to stereo analog converters. The audio sample rate is user
adjustable in stand alone mode using DIP switches or selectable from the C2-7310
menu when connected.
A2-7342
provides an HD-44 to 8 Analog Stereo (4-in/4-out) on XLR’s and a DARS
reference input on a BNC connector. This unit contains four high quality stereo
analog to AES3-id converters, plus four high quality AES3-id to stereo analog. The
audio sample rate is user adjustable in stand alone mode using DIP switches or
selected from the C2-7310 menu when connected.
