Sansui AU Alpha 607 amp use
technics sb6 speaker use
Integrated amplifier adopting α-X balance circuit.
Sansui’s original α-X balanced circuit is adopted as a power amplifier part.
In the α – X balanced circuit, the signal circuit, the power supply circuit, the NFB circuit thoroughly make the signal independent from the ground, IHM distortion etc. are eliminated. In addition, by installing a balance amplifier in the pre-section, α-X balance transmission as well as α-X balance input can also be transmitted.
In this circuit, since the + side and the – side of the speaker are driven by dedicated amplifiers, it is possible to control the movement of the speaker on the amplifier side.
The α – X balanced power supply is adopted as the power supply part, and energy supply is carried out independently of the ground. There is no noise mixing from the AC line than this, preventing unbalanced current and ripple current from flowing into the speaker. In addition, the power supply system separates the power stage and the voltage amplification stage separately, eliminating mutual interference.
A super heavyweight transformer is adopted as a power transformer, and a Great supply capacitor is adopted as a condenser.
The newly developed solid chassis is adopted as the chassis structure, and electromagnetic wave noise is cut while aiming at high rigidity.
We adopted the CF 5 (Chassis · Fixed · 5 point support) insulator on the legs, and by placing a fifth insulator with compliance near the power source where the weight concentrates, we balance the load and realize the mechanical ground doing. CF12 (chassis · fixed · 12 point fastening) bonnet is adopted as a hood. In the CF12 bonnet, resonance and vibration are suppressed by fixing the U-shaped rigid bonnet determined from the vibration analysis result to the solid chassis using twelve screws which are much larger than before. MM / MC phono equalizer adopts FET input. The source direct function is carried and all sources can be connected directly to the α – X balanced circuit without passing through the accessory circuit. Tone control can also be used during source direct. Tone control with defeat is carried. Gold plated terminals are adopted as the terminal of CD, Phono, Tape / DAT – 1. Power cord with polarity indication is adopted. OFF The REC selector with the position is carried. The front panel is glossy & hair line finish with aluminum material.
