This loudspeaker and fan controller has been specifically designed to suit the Ultra-LD 100W per channel amplifier described in the March and May 2000 issues. Not only does it provide muting at switch-on and switch-off to prevent any thumps from the loudspeakers, it also protects the loudspeakers against catastrophic failure in the amplifier. In addition, it provides temperature control for the fan-cooled heatsink, switching the fan on if the heatsink temperature rises above 60°C.
