LED VU Meter provides fast, accurate visual indication of
the status of power amplifiers.
This module consists of 4 independent meters. Each meter is
represented by a bargraph comprising of 10 rectangular LEDs.
Each LED signifies a 3dB increase in power output, with the
Red LED at the top indicating full power. Metering mode is
RMS power output.
For best performance, the AuxPsu Kit
is recommended. The 3 voltage regulators ensure that the LEDs
maintain the same brightness even when all 40 are lit.
