Hi can anyone explain the behaviour of the led indicator on a BP 25 pre amp?
When I wanted to play some music the led had become red while not have touched the amplifier (button/switches). Before it was green.
In the manual I see the explanation:
The three colour LED (light emitting diode) located on the front panel lights RED when the output is muted
But why was it muted (or is there another reason the pre amp led switches from green to red??
