KAY DSP Sona-Graph Model 5500 Acoustic Analyzer + Model 5500-1 Keyboard

Description

Thank you for your interest KAY DSP Sona-Graph Model 5500 Acoustic Analyzer + Model 5500-1 Keyboard
This instrument was removed from a lab that recently sold off some assets
The sonagraph analyzer is clean and boots to the screens pictured
We were able to use the included 5500-1 keyboard to scroll through menus and adjust parameters on the analyzer
Please note we lack the equipment to test the performance of the analyzer - Just know it may require service or calibration before it can be returned to use as we are unsure when this was last done
Feel free to ask any questions and we will do our best to get back to you promptly
