ADC Sound Shaper Equalizer Spectrum Analyzer SS-415X - RACK EARS! - Tested

Description

I did connect this equalizer to my stereo system and it does what it was meant to do .As you can see from the photo, three led lights are out. It looks like it would require some effort to replace the leds that are not lit. The frequencies of the leds that are not lit are 4k, 16k and 32k.  My hearing only goes up to 4k and I can hear the increase/decrease in the frequency  . My wife can hear that the 16k frequency is working as well. As for the 32k frequency, I doubt anyone can hear that frequency since the normal frequency range that the human ear can hear is 20hZ - 20000hZ. This item has to be shipped in a 20" x 16" x 8" box and will weigh approx. 14 lbs so please check the shipping cost to your location before bidding.
I will not be able to ship from Aug. 23- Aug 31
The SS-412X uses a fluorescent indicator tube which has 156 separate segments plus 26 segments average response indicator for display to analyze sound source frequencies and room acoustics.
