Power monitoring for your own amp

In-Car audio, Disco Equipment

k4021.JPG (8764 bytes)These power meter are designed to give a visual representation of the output power from amplifiers built around the 300W MOSFET amplifier modules (K4010).  A visual indication of the instantaneous power output of your amplifier is useful  in that you can 'see' if you are about to exceed the loudspeakers, maximum input power level, or by running the amplifier into clipping, which can easily damage the tweeters. 

 

Two boards, one board for each channel, are mounted vertically to provide a professional visual display of power output for each channel.   If the amplifiers are bridged, the meters are mounted horizontally and connected in series.  Each board uses 12 LEDs to indicate the power out, and 16 LEDs for scale illumination.  The scales can be 0.001W to 100W/8ohms or 0.002W to 200W /4ohms (mounted vertically) or0.001W to 400W /8ohms (mounted horizontally, divided over 24 LEDs) for bridged mono.  The boards require ±40V DC that is supplied by the amplifier.
