The Switcher ...
The AES-302 is a two input switcher which can operate automatically. When placed in the automatic mode, the unit
monitors the incoming audio stream and can switch to an alternate path on user selectable error flags, loss of clock or
user defined silence. The unit can be commanded remotely or locally to switch as well.
The Distribution System ...
Up to four outputs are available Order any input or output configuration that meets your needs. The AES-302 can
support AES, SPDIF and Optical interfaces.
The Diagnostic Monitor ...
The unit features complete error flag information with memory retained to aid in troubleshooting. Slipped sample,
CRC error, parity error, coding error and unlock status are available. There is a sample rate indicator included too.
The D/A Converter ...
The AES-302 features a 96 KHz 24 bit converter with balanced output for professional analog applications. There is
also a front panel headphone output for confidence monitoring.
Standards Conversion ...
The unit can be ordered with AES-XLR , BNC, SPDIF or optical I/O in virtually any combination desired. There is
complete flexibility negating the need for outboard standards converters.
The AES-302 can be used as a transmitter or studio audio switcher, digital to analog converter, or diagnostic
monitor. It is well suited to broadcast and recording applications. It features a rugged steel chassis for excellent
shielding. All automatic switching functions are user programmable. Select the errors that you want to switch upon.
