[QUOTE="gbyleveldt, post: 54435, member: 122"] Is this something new? That happens when an amp stabilises to its DC operating point at switch on. Most modern amps have an "anti-thump" circuit that disconnects the speaker during this switch on phase, so that the speaker is protected against potentially harmfull DC voltages. If the amp never used to do this, but does so now, then the DC protect relay has fused its contacts and this should be seen to immediately. [/QUOTE]
