Resistor R5 acts as the input preference resistor for IC1, whereas D7 is the diode that guards Ic1 against extremely negative voltage. Capacitor labeled C2 receives the output signal from Q1 and takes it to IC1. A fine-tuned audio signal then is fed to a standard low emitter built around BJT Q1, which can hold ten times higher. The input signal of the gadget enables only sensitive modification of the circuit to the required intensity. The above configuration only allows 0.12 V waves in the first LED lights, 0.24 for the second light, and 0.36 in the third lighting. Hence known as an easy maximum level sound volume detector. The 10 LED VU meter circuits' high sensitivity fits any standard sound system. A 24MV is enough to illuminate the highest signal indicator. The meter circuit schematic features the strongest of all circuit transistors.Ģ0 to 40 LEDs Meter Circuit Diagram 10 LED VU Meter CircuitsĪ 10 LED VU meter displays six signals when connected to an amplifier. Additional transistors translate to more voltage-current input and higher power wave strength capacity. Then circuits C1 to D2 signal to the voltage doubler rectifier circuit, and all transistors labeled Q1 to Q10. An input signal from the power amplifier goes to VR1 to adjust the amplitude produced by the input signal to a proper level. The diagram below shows a perfect example of the 20 to 40 LED VU meter. If you want a 20 LED meter schematic circuit that drives LED up to 20 PCs, then purchase a 40 LED VU meter. The version of the 25 LEDs circuit supports stronger sound waves than the 5 LEDs meter circuit.Ģ5 LEDs VU Meter Circuit Diagram 20 to 40 LED Meter Circuit Schematic Therefore, the transistors drive every transistor to produce much more light. The addition of 25 LEDs enables the audio signal into more voltage. Dual incoming AC reciprocates the same to the DC voltage. ![]() The below diagram shows circuit transistors of double voltage capacity. The 25 LEDs VU meter circuit is an improved version of the previous LED5. LED 1 to LED 3 signifies appropriate sound power to your ears, while LED4 and LED5 offer a high power level. LED1 to LED4 displays the signal level, with LED1 showing the least light and LED4 indicating the most level signals. The voltage of each diode is 0.6V holding a sign of up to 1.8v. The audio signal is forwarded to each transistor featuring Q1, Q2, Q3, and Q4 through resistors R5-R8. Dividing the audio signal to decrease respectively consistently.However, the meter circuit is equally convenient.įour diodes of the VU meter, i.e., D1 to D4 passes the input to the audio signal. Reminiscent with the old aged versions, the 5 LED meter circuit supports just sound waves of lower strength levels. The VU meter has only a simple circuit with necessary parts only. ![]() ![]() Other types of circuits are the 5 LED VU Meter circuit, 10 LED meter circuit, VU Meter using DC voltmeter, and the peak reading VU meter by IC CA3130. The strongest of all meters is the 20 to 40 type which reads sound powers of the most robust sound systems. The transistor version VU meter is one of the most popular, cheap, and easy-to-use VU meters. When you apply the waveform of a speech to the meter, the movement specifies valleys and mountains within the signal. In the case of compound waves such as speech, the volume unit meters show the values of the average and peak of a complex wave. Unique ballistics assists VU meters in calculating the power levels in audio frequencies. VU meters operate sound recording and reproduction systems to evade overloading and noise distortion. ![]() Voice unit meters feature dynamic characteristics used in measuring human ear responses to sound waves. Make the correct decision of an appropriate VU meter after reading the article! Purpose of a VU Meter This article illustrates the working of various meter circuits and the underlying mechanisms behind operating the gadgets. When a VU meter connects to a piece of audio equipment, it provides you with an opportunity to establish the strength of the sound waves. Do you need an appropriate gadget for measuring the level of sound intensity? Get yourself a Vu meter to help you realize the power of the sound going through your ears!
