Pioneer Elite SC-81 has 7 channel Class D3 amplifier and delivers 120 W (8 Ω, 1 kHz, 2 channel driven) and also has a stable performance at 4 Ω load. This receiver even supports front wide channels which is found only in a very few high-end receivers these days.
The Receiver has 4K passthrough up to 60p and 4K upscaling up to 60p.
Class D3 Amplifier
Pioneer Class D3 amplifiers contain advanced integrated circuitry technology creating unmatched power without sacrificing sound quality or performance. Class D3 amplifiers use a Direct Signal Path Design to provide the shortest audio signal path possible. By eliminating EMI filters, feedback loops, and current limiters of previous designs, Class D3 reduces ringing distortion and noise, especially in the high frequency audio band.
The power consumption of the Digital Class D3 Amplifier is significantly lower than traditional A/B amplifiers - letting you save energy and generate less heat without compromising performance. The Digital Class D3 Amplifier uses a simple structure employing a straight signal path, resulting in improved sound quality requiring less energy than competitive models yet producing more simultaneous power output. This direct signal path means no EMI filters, feedback loops or current limiting - a true engineering art. Unlike traditional designs, these amps deliver the strength to handle multiple low-impedance speakers without dramatic power loss. The efficiency of Class D3 means cooler operation while drawing just a fraction of the power consumed by conventional amplifiers, enhancing and extending component life and reliability.
Advanced Sound Retriever
Compressed music enhancement in Pioneer Elite SC-81 is done by Pioneer’s Advanced Sound Retriever. Hear the detail, warmth and clarity, the way the artist intended it, from all of your highly compressed MP3 and WMA files stored on USB, Smartphone and portable media players. By restoring data that tend to get lost in the digital compression process, Pioneers Advanced Sound Retriever Technology enhances audio reproduction all the way upto 20 Khz frequencies.
