Audio Wattmeter Circuit with LM3915 ElectroSchematics Take note that the LM3915 indicates only the positive swing of the signal. Anyway, by testing amplifiers it does not matter anyhow since a sine wave is normally used as a test signal. To test the circuit without using an actual speaker, you can connect a dummy resistor with a value of either 8 or 4 ohms. PCB layout and parts for the audio wattmeter LM3914, LM3915, LM3916 Differences | Electronics Forum ... An audio power meter, although I ran into a problem with part of the design. The circuit has 4 display modes; Dot, Bar, Dot with delay, and Bar with delay (delay meaning that there is a second VU meter connected to the LEDs in the same way as the first, but it's peak detector has a higher capacitor). VU Meter LM3915 IC to control high power LEDs | Forum Usually one of the peak detector circuits shown in the datasheet is used on an LM3915 VU meter so that it holds an LED turned on long enough (about 30ms) so that you can see it. Without a peak detector circuit then the upper LEDs will be a dim blur.
