BrightEye 30

Audio ADC and DAC, Bi-directional

BrightEye 30 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 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, and channel shuing
are accessed through BrightEye Mac or PC software. A
variety of audio connectors and adapters are available for
integrating BrightEye 30 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.
