Stereo power amplifier announced as the top who
attained the maximum output and the minimum distortion simultaneously in the mac
power amplifier group, and a model.
The stereo has realized Oide power
of 1200W in 600W+600W and a mono-operation of bridge connection. Since this
consecutive output is using the output transformer, it does not change to
2ohm-8ohm (they are 1ohm-16ohm at the time of a monophonic recording).
Moreover, the power margin which can supply the dynamic power of 2,200W+2,200W (at the time of a mono-operation 4,400W) is realized also to a heavy load lower 80% than a rated impedance. And it has the output current capacity which attains to 200A at the maximum, and the powerful speaker drive is realized.
power device of a total of 36 9 parallel is adopted as an output stage, and the
exothermic is reduced by the large-sized heat sink or the automatic tracking
bias circuit with the operational stability of the power stage by an output
lance. Furthermore, when a prolonged high power operation continues, the low
undesired-sound heat-dissipation fan of two velocities operates, and
low-temperature degree operation-ization is attained.
preparation for an emergency over-temp, the auto-return type power-source
contact breaker is built in.
In order to correspond to the excessive
input exceeding a clipping output, the power guarding system original with a mac
is carried, and gain is automatically dropped at the time of an excessive input.
Moreover, to excessive electric currents, such as output short-circuit, the
sentry monitor system is controlling the output current.
The new mac
circuit which does not generate crossover distortion, loading of a balanced
amplification, and strict impedance distribution of each stage and examination
of a stream-composition part were given to the circuitry, and the low distortion
is realized to a minute output area with the Oide power amplifier in it.
The large-current capacity gilding terminal is adopted as an
