All ADAM products are designed and manufactured to the highest quality standards.

However, if any problems with your D/A converter card occur, we recommend to

proceed as follows:

5.1 Problem: The blue “D/A” LED on the frontpanel is glowing but there is no audio

signal:

• The “D/A” LED only glows when a valid digital audio data stream is being re-

ceived correctly. If there’s no audible signal, there probably is ‘digital silence’ (i.e.

the channel is muted via the mixing desk, etc.).

5.2 Problem: I have plugged in a cable that surely carries a valid audio data stream

but neither is the “D/A” LED glowing nor is there any audio signal:

• Have you chosen the correct input with your D/A converter?

• Are you using a speciﬁed digital cable, not longer than necessary and in one

piece?

• Have you accidentally plugged an AES/EBU digital cable into the analog input?

5.3 Problem: I can hear parasitic noises.

• If you are using word clock: a) Does its rate ﬁt the digital signal and b) is it really

sample-synchronous to the digital signal?

• Some word clock splitters allow for multiples of the incoming frequency. Please

make sure that you have not accidentally set for a multiple.
