Audio Analogue Maestro Anniversary AIRTECH is given by a chain of fully balanced amplification from the entrance to the final stage where returns unbalanced to connect to the speakers. All stages are deprived of global feedback. The output power is 150W at 8Ω with downsizing of the driver and final stages now use 4 channel transistor pairs. A single gain stage followed by the output buffer. Stability is maintained by DC Servo who work at minimum frequency, a few tenths of Hertz. After 15 years resurfaces a refined unit of considerable power, impedance and easy to fly. Master amplifier consists of 3 elements Power supply 1 600VA with a transformer for each channel, full wave bridge rectifier with ultrafast diodes 50A, the filtering capacity of 67,200 uF, the firing with controlled current cue from resistors excluded from the signal path. Amplifier 2 2 separate amplifiers as masses and that as power supplies, dual mono configuration. On the printed copper it is twice the nora, optimizes signal paths and keeps the symmetry of the stadiums. 3 Preamplifier preamp dual mono. behind the connectors there are the relays of the channels followed by a buffer balanced to isolate the amplifier from the source, the input voltage can 6VRMS, buffers balanced IN and drive out in class A the four chips of the volume. There is no kind of global feedback in the Master. then there is the pramplificatore that amplifies until 12dB. Then there is an amplifier and a preamplifier a separate final.
