What will I receive? 2 pcs x Fully Assembled KIT LM358 Audio Level Indicator as pictured (VU Meter). Sample Video: View sample video --HERE-- Description: The LM358 is implemented as an amplifier to the audio input provided by the microphone. Note that the microphone can be replaced and instead use it as line input. Line input example: Audio output from a CD-Player/MP3 Player etc. If the user decides to utilize the audio output from an already amplified audio signal, then the sensitivity of the VU Meter must be set to minimum. The sensitivity can be adjusted by the 470 KOhm variable resistor (please refer to circuit schematic for details). The remainder 5-LM358s (bottom of circuit schematic) are used as voltage comparators to indicate the audio/sound signal level.
