A2D-1 Manual PDF File 75 KB
The A2D-1 is a high quality, low noise analog to digital converter for
demanding professional applications.
The signal format (AES/EBU or S/PDIF) and the sampling frequency are selectable
from the front panel. The input gain is adjustable using the recessed front
panel controls. Clip indicators for left and right warn of input signal
overload.
Analog audio input connectors are the balanced XLR type, to interconnect readily
with most types of equipment. The AES/EBU and SPDIF output connectors are XLR
and RCA types, as per the respective standards.
