AudioSource One Equalizer Spectrum Analyzer Microphone made in Japan , this is a extremely rare microphone that was included in the AudioSource One Equalizer for balancing a room for perfect sound.To find one with the factory stand is impossible. There is a very small 1/4 scuff ( as pictured) . I do not have the instructions for it please google that information.Add this to your vintage AudioSource One Equalizer Spectrum Analyzer to complete it. Thank you
