Sansui QS 4 Channel Amplifier QA 7000
www.youtube.com/user/sakamatra1
Year 1973 − 74
Specifications
Four-channel Integrated Amplifier.
The new synthesizer functionality / decoder functionality by the newly developed 2-4 translation encoder are carried.
All schemes, such as 4ch source not only by a regular matrix but the formation of 4ch and SQ scheme of 2ch and a discrete, are supported.
The pure complimentary OCL circuitry is adopted as a power part.
The three-step hardwired-connection equalizer circuitry is adopted, and it has become 270mV of maximum permissible inputs.
The BTL interconnection of 40W+40W is possible.
