Peak indicator for loudspeakers

Peak indicator for loudspeakers
This little circuit, designed and marketed as a kit by ELV, provides a visual warning when the maximum drive power to a loudspeaker is approached. The sensitivity of the circuit can be set to power levels between 1 Wand 300 W. Connected in parallel with the loudspeaker terminals, the peak indicator is simple to build, and does not require a separate power supply.
