OOperation
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 CHAKRA 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 shut
down 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 components connected to the amplifier is faulty). Try switching the unit
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.
