K89 Stereo VU Meter

K89 Stereo VU Meter

This kit provides a simple, low cost stereo VU meter. Two LM3915 dot/bar display driver ICs are used to drive 2 rows of 10 LEDs (14 green, 6 red) in a moving bar display. Each row of LEDs spans a power range of 0-30 dB in ten 3-dB steps. This VU meter indicates "peak music power" when used with audio amplifiers. The kit accepts a wide range of supply voltages (+3VDC to +25VDC - not included). An ideal add-on for any of the amplifier kits. Dimensions = 65mm x 42mm.
