Overview

Audio A/D Converter Board. Installs as option into PFV-L10 frame. The BKPFL751 is a dual channel audio analog to digital converter board that accepts up to two analog audio stereo inputs and converts them into two AES/EBU format outputs. The signals carried by the two AES/EBU outputs can be interchanged. Conversion is at a resolution of 24 bits and at a sampling frequency of 48 kHz. Either a video reference (NTSC, PAL or HD) or a 48 kHz audio word clock can be used as a reference signal. A word clock output is available by setting an internal switch on the board so that other cascade-connected BKPFL751 boards can be operated synchronously.
