2. Brief product overview
It is relatively easy to design an amplifier with very impressive specifications, but our
listening tests over the years show us that, important as they are, there is so much
more to an amplifier design than specifications for true musicality.
Here are some of the ways we have achieved this:
Electronic Components in the signal path: All chosen for their inherent sound
performance qualities.
Power supplies: One of the critical areas of any quality audio equipment.
The AT2-2100 has dual mono power supplies from two audio quality 160VA
transformers, each supplying 16,000uf capacitance storage on each channel, and
separate dual mono power supplies for the pre-amplifier. Individual stages ensure a
clean supply, lowest noise and isolation between circuits and incoming power supply.
The design incorporates excellent EMI/RFI (Electromagnetic and radio frequency
interference) rejection to prevent this now ever present form of audible ‘noise’ from
entering the amplified signal path.
