EAM LAB CLASSIC AMP 202

We have entered a new era of high-quality music playback components. CLASSIC 202 has been designed with care and attention to the smallest details, both internally and externally.

A new circuit design, latest generation devices, a new design for power transformers. All mixed with our twenty years of experience in the sector to guarantee sound reproduction with absolute fidelity.

The new transformers guarantee stability and precision of the sound message even at low impedances and high listening pressures. The proven dual mono implementation provides greater signal stability and better channel separation which translates into a wide, deep soundstage with well-positioned instruments within the sound message, making the speakers literally disappear.

This amplifier is able to drive a wide range of speakers, thanks to its power reserve and inexhaustible current. Furthermore, its elegant and modern design fits perfectly into any environment, making it a perfect complement to your audio system

The heart of our performance: the power stage

the true heart of every amplifier, especially for our amplifiers, is for us a given of extreme care and detail of fundamental importance, resources and commitment.

CLASSIC 202 is equipped with two transformers with separate windings and wound on a single core for a total power of 1,200 Va which power the rectifier circuits mounted on a single PCB without loose wiring such as to allow a connection without contact resistors.

This design shortens the electrical path from the transformer to the final output stages, reducing overall impedance and allowing the circuit to respond faster while better controlling the speakers and more accurately.

The technology in our transformers

DIMENSIONS and WEIGHT: it is an almost certain data to ensure good performance, however these two measurements if considered as an end in themselves do not guarantee the final result. It is a set of further additional factors that determine the difference between a good transformer and an excellent transformer.

We cannot tell you point by point how we build our transformers being subject to factory veto but we can describe the major requirements to understand the efforts implemented in 20 years of research, study and evolution of materials that we use on a large scale.

Such as an extremely low induction, toroidal cores made of iron and magnesium powder, innovative coil winding and interlacing technique and last but not least, a copper magnetic shielding throughout the body.

You won't hear a more stable and silent transformer than ours!

Balanced input stage, our philosophy

the most delicate, fundamental part that must be treated with extreme care, because it is also this stage that overall determines the general performance of reproduction

this delicate task is entrusted to our proprietary HDCA modules now in their third version. Today even more refined, clear and transparent.

we assemble them with components selected for their linearity and bandwidth characteristics. The circuit operates in an open loop and the feedback is so low as to become practically negligible.

The circuit operates in pure class A and does not use decoupling capacitors across the various signal processing stages.

The power stage

revolves around a circuit design in helmet configuration. This tested configuration of ours allows a wide and extended bandwidth and the driving of the power amplifiers takes place via a Darlington type configuration.

6 pairs per channel of latest generation bipolar transistors ensure reliability and stability in any conditions of use, load or current demand.

A new integration of the circuits with SMD components allows shorter signal paths, greater noise rejection and a notable decrease in "microphonics" due to vibrations

The power transformer, in addition to being shielded, is mounted under an iron cover which further increases its rejection of disturbances. The entire filter bank and the rectifier diodes are instead mounted on a PCB with 70 micron copper without air wiring.

This decreases the contact resistance providing a higher current input and with greater transfer speed increasing the damping factor and control over the speakers
