FAQ
In general, in case of technical troubles check the electrical signal connections and the power
supply (LED at converter glows) first. If this turns out to be not helpful, we arranged the
following questions and answers for you to find the cause and solve the problem.
Problem Description
Possible Cause/Possible Solution
No or just very low
audio output.
Is the volume correctly adjusted at the playback device?
Is the signal source set on digital audio?
Is the amplifier set on the right input interface?
Is the proper digital output format (PCM Audio, Stereo)
used? For the use of the converter with a Dolby Surround
device, you need to adjust the stereo out format. Otherwise
different transmission protocols may lead to very low or
even no audio signal.
Is the signal cable to long? Or even defective?
There is a supply noise
Do the cables have a proper distance to transformers or
similar devices?
Are converter and amplifier connected to different circuits
(ground loop)?
If you use the Cinch input on the digital side, ground loops may
occur, especially with source devices using a switching power
supply like notebooks.
Is the supply noise still there if the
Notebook runs on battery operation?
The signal is distorted
Is the right output format PCM (Dolby Digital Audio) used?
Is the correct amplifier input used?
Some sound systems have input interfaces for record players,
which are more sensible and not suitable due to possibly
occurring distortions.
Is the volume at the playback device set to high?
