VM202 weak left channel output

I was testing the module and I only get decent output on the right channel. The left channel’s volume is much lower and has some buzz in it.
I output the line-out to the Velleman MK190 (which works fine with a standard mp3 player connected…)
Any idea what could be the problem?

If there is no wiring problem and if the problem is not related to the MP3 file, then we suspect the unit.
In that case, please return it for inspection/exchange to:

Velleman Projects Tech. Dept.
Legen Heirweg 33
9890 Gavere

The wiring is ok. I have tried different mp3 files which play ok on a computer…
Is there a warranty program/payment of shipping costs?

Sorry, warranty only covers return shipment, not shipment to Velleman.
If you want to avoid this cost, you can return the unit to your Velleman distributor.
