Troubleshooting - Roksan Audio K3 User Manual

If you suspect that your ROKSAN K3 Integrated Amplifier is not operating
properly, you should check all the connections carefully. Pay particular
attention to speaker phasing and channel connections. Phono plugs should
be fully inserted - a frequent cause of problems is due to the phono plug
surrounds not making proper contact. On the next page are some
commonly encountered problems with suggestions for possible cures. The
list is not exhaustive: If you have any unresolved problems, please consult
ROKSAN or your appointed ROKSAN dealer or distributor.
