Troubleshooting
No power Y Check the power outlet. Y The AC-Terminal fuse may be blown. Disconnect
power cables and determine its status. If blown: check all AC-cables for damage and correct connections and fix problems. Replace the fuse with a corresponding one. Y The internal fuse may be blown. This fuse is not user replaceable. Please contact Hypex Electronics for more information about service and repair.
No Sound Y A protection might be triggered. Is the module
overheated? Try cycling the mains power. Y Check the volume and mute settings. Y Check if Headphones are activated. Y Check optional trigger settings. Y Check the source signal. Y Check all the cables.
Poor sound or noise Y Check if the signal is not inverted. Inverted
signals might cause one of your speakers to be out-of-phase. Y Is the amplifier clipping? Y Check all connections.
Hum Y Use balanced connections for best system
performance. Y Use grounded wall sockets.
Heat Y The PreAmplifier Kit will get warm/hot when
used intensively, this is normal and therefore no reason for concern.
Balanced/unbalanced connections Y The PreAmplifier kit is equipped with balanced
and unbalanced inputs. If all the unbalanced inputs are already in use and your source does not provide a balanced output but only an unbalanced output you can use one of our interconnects to connect both properly.
