2 or 4 Chnl Audio Analog to Digital Converter w/ Delay DESCRIPTION
FEATURES
The ADC6800+A4BC and the ADC6800+A2BC are analog to digital audio converters with delay. They are able to handle analog to digital conversion applications (4 or 2 channels). PART NUMBERS, DESCRIPTIONS: ADC6800+A2BC Audio analog to digital conversion, two channels analog audio input, two AES coax and/or two AES balanced output (the second AES output channel is the copy of the AES1), 2 frame slots required, housed by the FR6802+XF frame only. ADC6800+A4BC Audio analog to digital conversion, four channels analog audio input, two AES coax and/or two AES balanced output, 2 frame slots required, housed by the FR6802+XF frame only. 1 AES OUT
