The Klimax contains two power supplies. The small, auxiliary one runs as long
as the mains switch is on and power is present. It powers circuitry which
detects the presence of an audio input signal, and the blue front panel LED.
The signal detector is very sensitive but waits about one second before
powering up the amplifier to be certain the signal was real, not just noise.
When powered up the Klimax will stay on for twenty minutes after the last
signal was detected, then revert to standby. The detection threshold has
been found over many installations to be a good compromise between
sensitivity to low level signals and immunity to noise. However, the residual
hiss level from phono preamplifiers at moderate volume settings can be
enough to trigger the signal sensor. Mute the preamplifier or turn the volume
down after use to prevent this happening. If there is audible hum from the
loudspeakers then you may have enough noise present to trigger the signal
sensor. Always try to eliminate the source of the hum, as this is essential
for a system to sound its best.
