The BKPF-L752 is a dual channel digital audio to analog
audio converter board. It converts each of two AES/EBU
stereo-digital input signals into two monaural analog audio
signals at a resolution of 24 bits/sample at 48 kHz. A
de-emphasis function is provided.

Features

* Converts AES/EBU digital signals to analog audio
signals * 24 bits conversion at 48 kHz sampling frequency
* Dual AES/EBU inputs are each output as two analog
signals * De-emphasis ON/OFF selectable with on-board
switch * AES/EBU channel status lamp *
