Technics - SH-GE90 Equalizer

The Technics SH-GE90 is a vintage digital sound processor (DSP) and graphic equalizer produced between 1992 and 2002, highly regarded in the audiophile community.
The equalizer for sale is in perfect working order and the front panel is in excellent condition, but it shows signs of aging (retouched) on the metal chassis, as highlighted in the photos which are an integral part of the description.
Main features
Digital sound processing (DSP): the SH-GE90 uses DSP to provide precise, repeatable, memory-based sound adjustments.
Built-in equalizer: includes a 24-band adjustable equalizer with a control range of ±12 dB. This allows detailed customization of the audio frequency response.
Parametric equalizer: like a digital parametric equalizer, it can selectively boost or attenuate three of its 24 available center frequencies. The 'Q factor' for this effect can be set to a wide range (1.8) or narrow (0.7).
Preset modes: includes several predefined EQ modes, including 'Heavy', 'Clear', 'Soft', 'Vocal', and 'Auto-stereo'.
Soundfield effects (Spatializer): presents a spatializer feature that simulates different listening environments. The presets include "Hall", "Live", "Disco", "Church", "Stadium" and "Theater".
Karaoke features: designed with karaoke capabilities, including dual microphone inputs with volume controls, vocal mute, key control, and echo effects.
Visual spectrum analyzer: a distinctive visual feature is its animated spectrum analyzer display, which uses LED/VFD bars to provide a real-time visualization of the audio spectrum.
Jog dial: An easy-to-use jog dial allows straightforward navigation and adjustment of the unit's sophisticated functions.
Connections: include loop-tape connections (Input/Output, Play/Record) for integration with other components.
