VU meter The original VU meter is a passive electromechanical device, namely a 200 µA DC d'Arsonval movement ammeter fed from a full wave copper oxide rectifier mounted within the meter case. The mass of the needle causes a relatively slow response, which in effect integrates or smooths the signal, with a rise time of 300 ms. VU Meter | Circuit Diagram A VU (Volume Unit) meter is a very useful device to show the audio level in audio devices from which a user can maintain a certain audio level and get rid of overloading the output. The figure below shows a schematic diagram of a audio level or VU meter circuit. Simple vu meter LM3915 vu meter circuit diagram ... The transistor Vu meter is available but it having some complicated circuits, and also need more components to build those circuits. The circuit is working by an input audio signal has to be injected to the lm3915 ic. then it will process the frequency of the audio signals and switch specific driver transistor ( inside the ic chip ) and turn on the output stage. Simple VU Meter Circuit – Jeff Thompson Simple VU Meter Circuit I recently bought a cheap VU meter on , which looks very cool but needs some circuitry to get running. Unlike vintage meters, which can be driven by the audio signal directly, newer (and especially cheap) meters require DC current. Wireless VU meter Using ATmega32A IC | Full Electronics ... VU meter is a standard device that indicates the signal level in audio equipment. Unlike other devices, this meter doesn’t require a physical connection between the audio source and the circuit. Wireless VU meter circuit. Circuit diagram of the wireless VU meter is shown below. Simple VU Meter Circuit using LM358 Electronics Projects In VU meter circuit LEDs are connected in Reverse Logic. It means negative terminals of LEDs are connected to the output of the comparators. So, when comparator output is the high LED will be off, and when output is Low then LED will be on. Application of VU Meter. VU meters have usage where one have to observe the change in audio. Audio Wattmeter or Audio Power Level Meter Circuit with ...

LED VU Meter Circuit Diagram using LM3914 and LM358 Working of VU meter Circuit is simple; at first MIC picks up the sound and converts it into voltages levels linear to the intensity of sound. So for a higher sound we will have higher value and lower value for a lower sound. LED Audio VU Meter 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). LED ‘Graph’ Circuits | Nuts & Volts Magazine This basic VU meter circuit gives a bar type display, with a dot type current drain.
