Technical Information
Description
The
919050 Digi-2
(
Dual Input AES to Analog Converter
) module allows selected Wohler Technologies products to receive
input signals in the
AES
or
SPDIF
digital audio data formats. Sampling rate and format selection are sensed and set automatically.
Two front panel mounted bi-color (RED/GREEN) LEDs provide visual indication of input signal status. The LEDs light GREEN
when receiving a valid, error-free data stream, but turn RED when errors are detected. See
Item 10
on page
10
for more information
about error detection and indication.
There are two
AES
inputs, which are configured with unbalanced 75
Ω
BNC connectors and balanced 110
Ω
XLR connectors. This
module also features a four-channel balanced
analog
line-level output, which can be configured with unbalanced 75
Ω
BNC
connectors or balanced 110
Ω
Phoenix or XLR connectors.
