A stereo power amplifier designed to achieve both high quality sound and high output, following the development technology of the M-1000.

It consists of the balance system which connected two sets of all the push pull drive unit amplifiers to the bridge, and has raised the performance.
The balance system requires a transmission system dedicated to positive and negative signals, but noise entering from the outside is canceled in principle, and distortion generated by the amplifier is also canceled by the output circuit. Signal transmission is possible.

In order to achieve the same performance as the monaural amplifier, the power supply unit employs a power supply dedicated to the left and right independent.
In addition, with two power supplies that simply halve the power capacity, the power supply impedance rises and becomes disadvantageous compared to the single transformer method, so the P-800 employs a large capacity transformer of 1.5 kVA that can be used for stereo alone. , Have enough room.
Furthermore, the filter capacitor has a large capacity of 82,000μFx4 and a total of 328,000μF.

In the output stage of each unit amplifier, the broadband transistor of collector loss (Pc) 130W is adopted by 7-parallel push pull composition, and it is a total of 28 pieces with two units of one channel. For this reason, the total collector loss has reached 3.6kW.
In addition, with respect to switching distortion at the time of small output generated in the output stage, the operating point is set strictly so that each element of PNP and NPN is not cut off (state that no current flows) by the input signal. .
In addition, the P-800 is equipped with a low-load impedance switch using a low-impedance drive system that utilizes the basic characteristics of transistors, and by switching the supply voltage, consideration is given to supplying large power even at low loads. The Thereby, 1 ohm load and 2 ohm load are also supported, and sufficient drive of low impedance, low efficiency flat speaker and electrostatic speaker is enabled by all load correspondence.

MOS FET equivalent to a non-switching Class-A drive is adopted as the preceding stage which drives the last stage, and it constitutes with cascode push pull. Moreover, the front stage which sends a signal to this MOS FET also has Class-A cascode push pull composition.
This has constituted the stable output stage with few distortions from the small output of a noise area to the large output of a rated output.

The class A cascode differential push-pull system is adopted as an input stage.
A cascode circuit is a circuit used for high-frequency amplification, stable operation over a wide frequency band, good input linearity, and a wide dynamic range.

The analog type large-sized power meter which can directly read the power between -60dB-+ 3dB by logarithmic compression is carried.
There is also a switch for turning off the meter and lighting.

The input terminal carries both balanced input and unbalanced input.

It is equipped with a natural persimmon finished sideboard.

An optimal fan is sold separately and can be set inside the sideboard when set in a place where heat dissipation is poor or when driving at high output for a long time.
