Panasonic SU-VX800 74,800yen(1991 release)

The Integrated Amplifier which adopted newly developed EDD (extended direct drive) and class AA scheme.

Newly developed EDD is adopted.
With this scheme, it is a voltage amplification gain. - The voltage amplification gain has linked directly the variable gain amplifier which can carry out variable from infinity to +30dB with the 0dB power amplifier of 0. Thereby, a noise level also becomes low and is improving the SN ratio in a real busy condition as a volume is lowered.

The class AA scheme original with Panasonic/technics is adopted.
By this scheme, separate amplifier is performing the voltage amplification and the electric-current drive, it is strong to a variation of signal level or a load impedance, and the stable transmit and amplification are realized.

The X-Pro twin capacitor which held down the mass transformer of an OFC coil, the oscillation, and the magnetic radiation in the power-source part is carried in right and left.

The power cord of the chassis and OFC adoption based on vibration analysis is adopted.

The phone input supports man month and MC.

The canon type balance input is carried.
