The amplifiers Studio have passive cooling. The housing is manufactured from a 1,5-mm steel with a plenty of the flutes for reliable cooling.
The amplifier Studio II has been designed specially for the company Reflexion Arts under RFP developed by Philip Newell. The amplifier has Bi-Amp construction. The power channel circuitry used for the driving the LF-speaker combines the advantages of classes A and G, that provides high linearity, efficiency, small heat dissipation and boosted reliability as a consequence. The signal path consists of the voltage amplifier and current amplifier whereas the total negative feedback is absent. The voltage amplifier is designed according to tracking cascode circuit working in a pure class A, that reduces the percepted distortion to the zero. The current amplifier is made on complementary circuit on bipolar transistors Sanken and operates in a dynamic class A. High efficiency is achieved owing to multilevel power supply (class G).
The signal path of low-power channel necessary to drive the HF-speaker concludes the voltage amplifier and current amplifier whereas the total negative feedback is absent. The voltage amplifier is designed according to tracking cascode circuit working in a pure class A, at outputs to 5 W in pure class A.
Audiophile circuitry and hand technology provide high reliability, perfect characteristics and excellent quality of sounding. The effective protection against overload (Overload Protection) as well as rapid fast solid-state tiristor circuit of loudspeakers protection reduces to zero the risc of their damage. There are protection from RF, infralow frequencies, from a short circuit and constant voltage on an output, from overheat of output stages and transformers, from an overload on an input up to +15 dB. A delay and smooth rise of a signal at a time of switch on.
