SANSUI SE-9 Stereo Graphic Computer Equalizer Spectrum Analyzer WORK Good Look Refurbished, Work Perfect On AC 110/120 and 220/240 volts Stereo Graphic Equalizer (1981-83) The Sansui SE-9 is a truly unique graphic equalizer that lets you attain flat response in any room, regardless of speaker response, furnishings or room size. Here's how it works: the calibrated microphone (included) is placed in a favorite listening position. Next, the SE-9's Analyze button is pushed. Automatically, a built-in pink noise generator is activated and the sound is picked up by the microphone. Response is sent to the SE-9's computer, which automatically adjusts each control - one by one - until response is flat. The Spectrum Analyzer lets you actually watch the SE-9 flatten response. Frequency Bands: 80, 160.
