An audio power meter includes a circuit for measuring the power of an
amplified audio signal outputted by an audio power amplifier to which the
audio power meter is connected. The circuit generates an output signal
indicative of the power of the amplified audio signal. A first bar
display includes a plurality of separately illuminatable segments
arranged linearly with respect to one another. Each segment of the
plurality of separately illuminatable segments is responsive to the
output signal of the circuit and is selectively illuminated in response
thereto. When the measured power of the amplified audio signal exceeds a
selected threshold power level, the amplified audio signal is attenuated.
