Norma is based in Cremona, a place where music has always played an important role. Cremona is the home of Monteverdi, Ponchielli, Stradivari, Amati and many other artists. For more than 20 years Norma has been involved in the study and implementation of sophisticated audio amplifiers. Technical skill and musical sensitivity must be merged together, in the same way in which the best musical instruments are made. In Norma we are convinced that the influence of audio electronics on the outcome of audio reproduction is much greater than commonly assumed. Listening to a Norma product can express this concept, better than words, closer than ever to live listening. The sound of Norma products is unique, represents a synthesis of parameters which often conflict with each other.
Dynamics, speed, and absolute transparency are combined with extraordinary musicality and a total lack of listening fatigue. The conflicts between solid state and valves are finally overcome, leaving space only for pure listening pleasure.
REVO SC-2
|
Into the preamplifier REVO SC-2, a pure and elegant style is combined with an refined technology. The entirely remote controlled, the REVO SC-2 model uses an exclusive volume control system called P.D.A.A. (Programmable Digital Analogue Attenuation). It is make by relays and precision resistor with 0.5 dB step an 127.5 dB range attenuation. Also, inputs and outputs selection is make by high quality relays; no any kind of Integrated Circuit is used in the signal path. All REVO SC-2 details are designed for match the modern operative features, with really high quality sound of High-End audio electronics.
The REVO SC-2 model is endowed with a variable luminous intensity plasma display which can be seen from far away and, through the use of a microprocessor and of a specific software, it combines simplicity and easy handling with high versatility, completeness and function customisation. The SC-2 preamplifier can be upgraded with Phono Board, with MCH-6 Multichannel Board or with DAC Board with USB & SPDIF inputs, 24 Bit, 192 kHz resolution . They may work in Active or Passive mode.

REVO PA-150
|
The features of REVO PA-150 make it an extremely versatile power amplifier. Its high power (140W/8Ohm), the ability to drive the most demanding speakers and sound characteristics, make it unique. Power, dynamics, speed and transparency are combined to make a total lack of listening fatigue and outstanding musicality.
These features make it a perfect match with the preamp REVO SC-2, which expresses the same sound personality. But, also for people who want to combine it with other preamps, the REVO PA-150 can become a perfect partner. For example, with the best tube preamps you can enhance the characteristics of sound, giving an extraordinary ability to drive the speakers without introducing any harshness in the sound and the listening fatigue often present in solid state amplifiers. The inside workings show that the technical refinement follow the same philosophy.
The REVO PA-150 uses a proprietary circuitry, regulated high-speed power supply, low noise and is built with a careful selection of the best available materials.
