Vintage Sansui 7 channels Equalizer with a reverberation amplifier! Made in Japan. The Sansui RG-707 is a classic piece of "Silver Era" Hi-Fi gear from the early 1980s. It’s a versatile unit that combines a 7-band graphic equalizer with a reverberation amplifier, allowing users to both shape the frequency response and add artificial "depth" or echo to their music. Allow also to plug 2 microphones or 2 instruments (e.g. guitars), with their own each equalization. Tested and working.
