Figure 1 - The LED VU Meter Circuit L1 to L7 will normally be green (normal operating range) and L8 to L10 should be red (indicating overload). This gives a 9dB overload margin when the unit is calibrated as described below. As shown, full scale sensitivity (with VR1 at maximum) is 4 Volts peak (approximately 2.8 volts RMS).
