Adevarata legenda vie a pietei Hi-Fi europene si mondiale, Rega, este prezenta de acum si in Romania,
datorita parteneriatului cu STEREO PLANET.
Recunoscuta pentru calitatea impecabila a produselor sale, Rega isi selecteaza foarte riguros partenerii.
Este unul din putinele Brand-uri care-si permit sa-si selecteze Distribuitorii dupa criterii legate atat de
competitivitatea acestora pe pietele in care activeaza cat si legate de calitatea oamenilor si principiilor din spatele acestor Distribuitori.
Tocmai de aceea, NE ONOREAZA acest parteneriat.
The Osiris is the culmination of Rega engineers 32 years experience in solid-state amplifier development.
A no compromise audio amplifier using state of the art surface mount technology and a fully symmetrical circuit.
Design
A super high performance, 162 Watts into 8 (250 Watt 4) dual mono amplifier housed in a custom Rega CNC
machined aluminium case with high thermal efficiency heat
sinks. Designed around “minimalist” high gain power amplifier and “passive pre-amplifier” circuit topology, a
passive volume control and a single stage of power amplification between the input and the speakers the
Osiris offers unrivalled performance and build quality.
Technology
The Osiris uses a low distortion high linearity and bandwidth common base voltage amplifier driver stage.
This type of symmetrical circuit topology will provide the
necessary voltage swings to enable the Osiris to drive any speaker system with the minimum of distortion.
Eight Sanken 200 Watt output transistors are used in a “triple”
high current output stage enabling the Osiris to drive even the most awkward of speaker systems with ease.
The cascoded differential input amplifier uses two low noise LED referenced current generators.
The open & closed loop feedback levels and gain bandwidth product components are optimised to give a tight
and controlled sound stage, especially at the low frequency end of the audio range. Nichicon audio grade
capacitors are used in bypass and decoupling positions. Electrolytic capacitors have been bypassed with polyester
capacitors where necessary improving on the HF performance.
Low inductance film SM power resistors are used in the output stage.
Power Supply
The Osiris uses two low noise purpose designed 400VA toroidal transformers using high-grade fully bonded
core material.
The transformers are mounted to the chassis using Rega’s innovative mounting technique, which eliminates
noise being transferred from the transformer to the case when the transformers are operating under arduous
mains (line) conditions with high levels of asymmetric mains (line) distortion.
These transformers combined with 40,000μF of Rega K-Power smoothing capacitors per channel, provide more
than enough current to drive the hardest of loads.
All the power supplies utilise fast recovery rectifier diodes throughout. (Fast diodes generate less high frequency
switching noise therefore giving rise to a cleaner DC).
The input and low-level driver stages are fed from a regulated symmetrical tracking power supply with a low noise
voltage reference, which provides a fully stabilised low noise voltage, ensuring the highest level of sonic purity.
All the dedicated audio power supplies feed only the audio circuits.
The input switching, display & micro controller and protection circuits have their own dedicated supplies, keeping
the audio signal path as pure as possible.
All these features amalgamate to create the supreme level of performance found in the Osiris and provide a
perfect partner for the Rega ISIS Cd player.
