The AES-404 4 Input Digital Audio
Switcher
The Switcher ...
The AES-404 is a four input AES3 compatible digital audio switcher. A convenient single rack unit digital audio
switcher with professional XLR connection throughout. Select channels from the front panel, GPIO or serial remote
control.
The Distribution System ...
Two AES digital outputs are available for distribution to independent 110 ohm balanced lines. Ruggged RS422 line
drivers provide excellent driving capability for long lines.
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-404 features up to 192 KHz, 24 bit convervsion with balanced output for professional analog applications.
There is also a front panel headphone output for confidence monitoring. Balanced analog left/right output conforms to
industry standard +4 dBm output for -20 dBFS.
The Rest of the Story:
Part of a series of digital audio products from BDI the AES-404 Digital Audio Switcher/DA/D to A Converter has
features that few switchers have which makes it suitable for broadcast, professional audio, recording, and ENG truck
use. Professional switching, distribution, diagnostics and digital to analog conversion all in one package The AES404 can even manage non audio standard AES formats for switching and distribution. DIP switch programming of
functions allows the user to customize which features for use in different audio situations. Lightweight aluminum
construction in a standard EIA rack enclosure makes the AES-404 a great solution for portable setups for transportable rack configurations. Don’t settle for so called low cost solutions that don’t use XLR connectors, require a rack
adapter kit or use “wall wart” power supplies. The AES-404 is a single EIA compatible rack enclosed product with a
rugged internal power supply.
