McIntosh MC252 525,000yen(including-tax, around the 2007 time)

Description
 
Stereo power amplifier which carries two technologies of representing a mac called a balance circuit and output auto FOMA.

A low distortion and Oide power are realized by adopting the balance circuit to which right-and-left both channels supply a power source independently for each circuitry.

Also in which 2/4/8ohm load intensity, an equivalent output is sent to each load intensity by wide-range output auto FOMA original with a mac in a wide band. Moreover, a speaker is protected from damage to the system by the fault of a power transistor etc.

When a difference arises in an input/output wave exceeding the maximum power capacity, the dynamic operating time, voltage, and electric current of the power guarding in which a comparator controls gain and controls distortion of an output, and an output stage are supervised, and the sentry monitor circuitry controlled to suppress an electric current in safe level is carried.
Furthermore, protection networks, such as DC protection, a temperature protection, a turn-on latency, and an in rushes protection, are carried.

The blue-eyes power meter is carried. It is also possible to turn OFF the illumination of meter.
