Audio Level Meter
The circuit exhibits a flat frequency response ranging from approximately 20Hz to over 50kHz. The input sensitivity is set at 100mV for full-scale deflection on a 100µA meter. It is constructed using two common emitter amplifiers; the first stage includes...
become a VU meter and homemade rhythm lights easy [megapost]
A post related to a do-it-yourself project for creating a VU meter and homemade rhythm lights that are easy to assemble.
The project involves designing and constructing a visual audio level meter (VU meter) that responds to sound levels, as well...
decibel meter
The circuit responds to sound pressure levels ranging from approximately 60 to 70 dB. An 8-ohm speaker captures the sound, which is then amplified by a transistor stage and one section of an LM324 operational amplifier. A dynamic microphone may...
IC DflIVE FOB VU METER
This circuit is utilized in high-quality stereo cassette decks that operate from either an AC line or battery power. It features a meter rectifier bridge integrated into the feedback loop of an operational amplifier (op-amp), which allows for highly linear...
vu meter 4
The circuit is connected in parallel with the output of a power amplifier and provides the signal level from the output. By adjusting the resistance R1 in the input circuit, the power indication can be adapted to the resistance of...
