Operation
General
The blue LED on the front panel will be dim when power is first
applied and will remain dimmed when the amplifier is in standby
mode.
Signal sensing
When an input signal is detected, the AKURATE amplifier is enabled
and the LED brightens. In the absence of an audio signal, the amplifier
reverts to a low power standby mode after approximately 20 minutes.
The signal detector is quite sensitive and if there is noise in your
system, such as hum or hiss, it could trigger the detector. If this
occurs, try to eliminate the source of the noise.
Protection
Operation
If an amplifier channel overheats or detects an overload condition, the
power supply for that channel will shut down in order to protect the
amplifier and the loudspeaker drive unit(s) to which it is connected.
Please note: all channels that are powered by that same power supply
will also shutdown so more than one channel may be affected.
Duration
Once the condition that caused the amplifier to activate its protection
has passed, the amplifier will automatically resume normal operation.
How long the channels remain in protection will depend on the cause.
If the protection operates for more than a few seconds, it could
indicate overheating which may take some minutes of cooling to
rectify.
A lengthier delay (10 minutes or more) could indicate a persistent
overload condition (e.g. one of the units connected to the amplifier is
faulty). Try switching the amplifier off at the mains for 30 minutes or so
and try again. If it remains non-operational, consult your retailer who
can examine your system and determine the source of the problem.
