The legendary McIntosh autoformer is a hand-crafted transformer with output connections for 2, 4, and 8 ohms, allowing an ideal impedance match between amp and speaker. An impedance mismatch between a power amplifier and a loudspeaker can cause distortion and a reduction in power. Without the faceplate, meters and.EXCLUSIVE MCINTOSH OUTPUT AUTOFORMERS.

Furthermore, when a prolonged high power operation continues, the lowUndesired-sound heat-dissipation fan of two velocities operates, andLow-temperature degree operation-ization is attained.Preparation for an emergency over-temp, the auto-return type power-sourceInput exceeding a clipping output, the power guarding system original with a macIs carried, and gain is automatically dropped at the time of an excessive input.Moreover, to excessive electric currents, such as output short-circuit, theSentry monitor system is controlling the output current.Circuit which does not generate crossover distortion, loading of a balancedAmplification, and strict impedance distribution of each stage and examinationOf a stream-composition part were given to the circuitry, and the low distortionIs realized to a minute output area with the Oide power amplifier in it.The large-current capacity gilding terminal is adopted as anMono: 1,200W (1ohm, 2ohm, 4ohm, 8ohm, 16ohm)Stereo: 0.005% or less (250mW-600W, both channel operation)(It is about a single-sided channel at the less than peek 1,200W and bothMono: 0.005% or less (a peek and less than 2,400W)It is less than THD2% to over-drive 14dB at 1kHz. 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 theExothermic is reduced by the large-sized heat sink or the automatic trackingBias circuit with the operational stability of the power stage by an outputLance. Since thisConsecutive output is using the output transformer, it does not change to2ohm-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. 1,600 (Evanston north chicagoland ) pic hide this posting restore restore this.Of 1200W in 600W+600W and a mono-operation of bridge connection.
