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.
