Network Receiver YAMAHA R-N803 145 W + 145 W ที่ 8 โอห์ม ToP-ART เทคโนโลยี และ โหมด Pure Direct 192 kHz / 24-bit DAC (จากเทคโนโลยี ESS) จากแบรนด์ YAMAHA
High sound quality circuit design based on the ToP-ART (Total Purity Audio Reproduction Technology) concept
ToP-ART Design and ART Base Ensure Optimum Sound When processing and transmission of the audio signal is simple and direct there is less chance of it being affected by noise and distortion. Yamaha’s amplifier design technology called ToP-ART features an I/O (input to output) Direct Symmetrical Design, with left and right channels organised in a straight, symmetrical layout for highest signal purity. In addition, the ART (Anti-Resonance and Tough) Base bottom chassis and a solid centre bar provide high-rigidity support and vibration damping. These Yamaha design innovations contribute to this amplifiers’ rich audio reproduction with abundant musicality.
High Quality Parts for Outstanding Audio Performance
Custom-made power transformer, custom-made block capacitors, two direct signal path speaker relays, one-point grounding system, aluminium-extruded heat sinks and other top-quality parts effortlessly handle demanding audio signal conditions. The quality of each individual part, as well as how they work together, basically determines the sound quality of any component. Yamaha uses only very high quality parts, carefully selected and tested
Optimised for the ultimate
For the first time in a Hi-Fi receiver, the R-N803 is equipped with the Yamaha Parametric room Acoustic Optimiser (YPAO), a famed technology used in Yamaha’s AV receivers. It measures the shape of the room, the material of the wall and the position of the speaker, and then automatically adjusts the sound to create the ideal response and sonic quality. The unit also features other advanced YPAO functions, including YPAO™-R.S.C (Reflected Sound Control), which actively corrects the important early reflection sounds that greatly influence sound quality, and YPAO Volume, which applies exceptionally high-precision EQ (equalisation), with 192 kHz / 64-bit operation. The result? You can create an ideal listening environment right in your home, just like that of a professional audio listening room.
Maximum sound purity
Pure Direct mode enables the music signals to travel the shortest possible circuit route, bypassing the buffer amp and the tone, loudness and balance controls to virtually eliminate any signal degradation, for the purest sound quality.
Sophisticated circuit design
The power amp block adopts a symmetrical and direct circuit layout based on the ToP-ART concept, featuring a parallel push-pull structure using a total of eight bipolar type power transistors (four each, on left and right) as its output terminals. And by minimising the lengths of the audio signal paths in the circuit design, we’ve lowered impedance to achieve superb drive power with a maximum output of 145 watts (per channel).
The R-N803 is equipped with Bluetooth® functionality to let you enjoy easy wireless music playback from smartphones and other devices.
Your music everywhere
MusicCast employs a high performance wireless network to deliver music and audio enjoyment. It can stream digital music content from your smartphone, PC or NAS to other MusicCast devices in your home. It can also share the music from external devices such as a CD player or TV connected to the R-N803. Audio content from Bluetooth-connected smartphones or tablets can also be streamed to MusicCast devices in multiple rooms.
Hi-Fi sound for your TV
The R-N803 is equipped for digital audio input with both audio and coaxial terminals. The optical is for receiving audio from a TV and the coaxial is for receiving audio from a Blu-ray Disc™ player. The audio stays in the digital domain, giving you pure, pristine, dynamic sound for all your entertainment sources, from sports and other programmes to movies and concerts.
Enjoy your records, too
The comprehensive connectors of the R-N803 include special phono input terminals, letting you easily connect a turntable and enjoy music from your vinyl record collection.
