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 W 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 \u0026amp; closed loop feedback levels and gain bandwidth product components are optimized 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 de-coupling 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"xxxlarge-6 cell module-2-content\"\u003e\n\u003ch2\u003e\u003cspan\u003ePOWER SUPPLY\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp\u003eThe Osiris uses two low noise, purpose designed 400 VA 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 40,000 Micro Farads of Rega K-Power smoothing capacitors per channel, provide more than enough current to drive the hardest of loads. All the power supplies utilize 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 stabilized 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 \u0026amp; micro controller and protection circuits have their own dedicated supplies, keeping the audio signal path as pure as possible.\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: large;\"\u003e\u003cstrong\u003eTECHNICAL SPECIFICATIONS\u003c\/strong\u003e\u003c\/span\u003e\u003cbr\u003e\u003cstrong\u003ePower Output\u003c\/strong\u003e\u003cbr\u003e162 W per channel in to 8 Ω\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInput Sensitivity\u003c\/strong\u003e\u003cbr\u003e160 W into 8 Ω, 250 W into 4 Ω\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eGain\u003c\/strong\u003e\u003cbr\u003e44 dB\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRecord Output\u003c\/strong\u003e\u003cbr\u003e215 mV into 100 k\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFrequency Response\u003c\/strong\u003e\u003cbr\u003e10 Hz (-1.7 dB point)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTHD \u0026amp; Noise\u003c\/strong\u003e\u003cbr\u003eLess than 0.05%\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower Consumption\u003c\/strong\u003e\u003cbr\u003e560 W at 1125\/230 V\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDimensions (W x H x D)\u003c\/strong\u003e\u003cbr\u003e434 x 122 x 350 mm\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003cbr\u003e25.6 kg\u003c\/p\u003e\n\u003c\/div\u003e","brand":"The Music Room","offers":[{"title":"Default Title","offer_id":51268128407833,"sku":"0305newrega","price":11600.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/4225\/1545\/files\/Rega_Osiris_Reference_Integrated_Amplifier_1__19828.1717212549.1280.1280.jpg?v=1759347210","url":"https:\/\/tmraudio.com\/products\/rega-osiris-reference-integrated-amplifier","provider":"The Music Room","version":"1.0","type":"link"}
