Audio Format Converters
Models A2-7300 Series
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 c onnectors 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 t he 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.
A2-7302 provides an HD-44 interface to 16 AES (8 -in/8out) 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 (8in/8-out) and a DARS reference input on BNC’s 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/8out), 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/4out) 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.
