The standard degree-indicator circuits which can be available in the market require connections to be made to the output of the player, which may now not be simply accessible. The audio degree indicator circuit described right here take aways this limit as it can be placed on the topic of the participant’s audio system and yet the specified impact can be realised. 

Remote Audio Level Indicator Circuit Diagram

As proven within the circuit, signals are picked up with the aid of the condenser microphone, which get further amplified through the noninverting amplifier built around one of the vital 4 op-amps of LM324. The remaining three, along with 4 op-amps of the 2nd LM324, are used as seven comparators to work as the degree detector, giving seven output degrees via seven colored LEDs. 

The sensitivity of the audio level indicator circuit is also superior by using various the 220k potentiometer. If a nice adjustment is desired, a four.7-kilohm potentiometer is also related in collection resistors with the 220k potentiometer.
