A friend of mine still owns a KN2000 and since a few 'gigs' the KN2000 has much to low output voltage. We have no idea what the reason might be. Can someone reply with a possible solution for this ?
IF I understand well, the general volume has decreased. Try this : - Restore factory setting "Overall Sensitivity" setting must be to 6 - Check dust underneath the speaker grids (must dismount the kb - a few screws)
