Evolution² Evolution² Switch off the amplifier and all sources before making connections to your sound system. When you switch on the system or change sources, set the volume control to minimum and turn up the level gradually. The position of your Volume Control is NOT a reliable guide as to the maximum capabilities of your system. Playing the system with extreme settings of volume and tone controls may damage the amplifier and loudspeakers. Do not connect loudspeaker terminals to the mains supply.
