Independent power supplies for each channel. Powerful 785 VA toroidal power transformer. Modular scheme topology. The possibility of starting from an external source of 12V direct current. 6 complementary pairs of output transistors per channel, designed for a current of 15 A, a frequency of 50 MHz. The operation of the output stage in the floating class A - AB (at small capacities in class A and larger in class AB) with a high value of the bias current. Gold-plated contacts of input RCA jacks. The input stages of the amplifier on field-effect transistors work in class A. Indicators of 220V power supply, standby / normal, overload.
