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
