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.

REVO SC-2

In the REVO SC-2 preamplifier, a pure and elegant style combines with the most refined technology.

Completely remote-controllable in all its functions, the REVO SC-2 model uses the exclusive P.D.D.A. (Programmable Digital Analogue Attenuation) volume control. It a system that attenuates between 0.0 dB and -127.0 dB in steps of 0.5 dB, with a typical precision of +/- 0.01 dB.

Plus, the input selection uses high-quality relays, no integrated circuit is used on the signal path.

The whole conception of the REVO SC-2 is tended to combine a modern operative functionality with the severity for audio signal typical of a devise which is really High-End.

Its plasma display with adjustable lightness intensity is always clearly visible from a distance, and thanks to the microprocessor management and a dedicated software, the REVO SC-2 combines simplicity and comfort with extraordinary versatility, completeness and functions customization.

The SC-2 preamplifier can be mounted with a Phono stage, and also updated to the Multichannel mode.

Finally, it can work both in Active and Passive mode.

- Extreme low noise, high speed schematic topology and wide band ( >2 MHz ).

- High filtering capacity (51.000 uF) with numerous (23) capacitors, to achieve low impedance.

- Toroidal power transformers specially designed for audio applications, low flow dispersion, low mechanical noise, high permeability magnetic core with consequent low output impedance.

- Full aluminium non-magnetic frame.

- Inputs & Outputs configurable RCA (unbalanced) & XLR (balanced)

- Inputs selection by relay with GOLD/PALLADIUM contacts.

The optional Phono board PH-3 for the REVO SC-2 preamplifier adds to the device the functions of impedance matcher, RIAA equalizer and preamplifier, to receive a signal from a turntable.

It has the peculiar characteristic, and probably unique in its genre, to be made in dual-mono layout: the two channels are placed on two independent boards, and the power supply is separately stabilized and filtered, to deliver the best possible quality.

It’s able to receive signal from MC (Moving Coil) and MM (Moving Magnet) turntables, simply by replacing an integrated circuit (provided as standard).

It’s possible to vary the load seen by the head by moving a switch, that commutates between 4 standard resistance values (100,500, 1K, 47 Kohm) and a user-definable value, which can be chosen by inserting a resistor.

The gain value is variable with a similar system, with a range that goes from 34 dB to 52 dB in six steps, plus a value definable by the user, again just by inserting a resistor.

The PH-3 board is made with very-low-noise components, which are able to handle turntables with a robust output, and also work perfectly with heads that have a lower sensibility.

With its very accurate layout, that makes the setting operations very simple, this board will let you appreciate at best the expressive nuances of an analog source, without compromising its natural character.

- Optional board, to be fitted in a main line board (Left & Right).

- 2 mono single mono phono board, independent for Left & Right.

- Both, MM & MC pick-up

- Two different OpAmp for MM & MC pick-up, can be easily swapped by the user, to achive the best S/N ratio.
