Testing the clipping indicators. The Hypex amplifier modules can assert their channel clipping flag if the output of the amplifier exceeds either a set voltage or current limit. The clipping flag from the Hypex amplifiers are non-latched which means we need to latch the clipping flags in hardware otherwise the software could miss it if it is relying on polling. As a result each channel can report the clipping status in real time by making the LED turn red for at least 100mS so it can't possibly be missed by the user. This tells the user that amplifier is being over driven and the level should be reduced !
Scope image of the first two channels of the amplifier being driven into voltage clipping.
Indicator LEDs turn red when its respective channel is being over-driven into clipping thus signalling to the user to reduce the level !
