An excellent thermal coupling between the FETs is assured by the absence of the otherwise usually

incorporated mica insulators. All FETs are selected with a tolerance of +/- 5mV to provide optimal current

distribution.

The optimal circuit layout, allows very short signal paths between the circuit board and speaker terminals.

This results in extreme damping factors which are necessary to control the loud speaker and architectural

acoustics. The damping factor of a power amplifier controls the tone of a loud speaker - not just through

attenuation of oscillations of the speaker itself.

Just as important is the ability to absorb the acoustic energy that is reflected back from the room to the

membrane of the speaker. Namely loudspeakers are, in complete reversal of their principle of operation, at

the same time microphones.

The acoustic energy that occurs in the vicinity of room resonance can be attenuated if it is absorbed by the

amplifier. Audio tests have shown that the high damping factor of the essential mono makes it very capable

of minimizing room resonance. The bass reproduction remains extremely controlled and clear, even to the

deepest bass tone.

Safety circuits against overheating, short circuit and extreme ultra sonic frequencies ensure that should such

faults occur your amplifier and any loudspeakers connected to it are reliably protected.
