BrightEye 30-D

Audio ADC and DAC, Bi-directional
Converter with Delay

BrightEye 30-D is a exible audio converter that can be
a two channel, bi-directional ADC and DAC, or it can be
congured as a four channel converter. Perfect in desktop,
post and broadcast applications, 24 bit processing ensures
beautiful audio.

As a bi-directional converter, two channels of analog audio
are converted to AES digital audio and at the same time an
AES stream is converted to two channels of analog.

Alternately, the unit can be congured as a four channel
AES to analog converter or a four channel analog to AES
converter.

BrightEye 30-D also serves as a sample rate converter.
For example, a digital 44.1 KHz signal from a CD player
can be fed to the input and a digital AES3id, 48 KHz signal
synchronous to the reference input will be output.

Audio mixing, level adjustments, channel shuing and
delay are accessed through BrightEye PC and BrightEye
Mac. Audio delay adjustments simplify signal integration.
A variety of audio connectors and adapters are available
for integrating BrightEye 30-D to any type of system.

A reference input is provided which allows digital outputs
to be synchronized to either a PAL or NTSC video signal or
AES reference.
