2/4 channel ADC and DAC bi-directional converter with delay , bi-directional ADC and DAC, or it can be configured 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 configured 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 shuffling and delay are accessed through BrightEye Mac or PC software. 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.
