digital home theatre technology high sound quality discover the pleasure of hd audio the new yamaha amplifiers and receivers enable you to enjoy the stunningly rich and beautiful surround sound offered by blu-ray disc players you can play sources that use the two lossy formats dolby digital plus and dts-hd high resolution audio as well as the higher quality lossless formats dolby truehd and dts-hd master audio digital top-art and high current amplification yamaha s digital top-art concept combines the latest and best technologies parts and circuit designs to maximise sound quality a new interior layout completely isolates the digital analogue and video sections and provides the shortest possible signal routes top quality parts include burr-brown 192 khz/24-bit dacs a lownoise discrete power supply and custom-made block capacitors high current amplification circuitry achieves high current power with low impedance for superior amplifier performance pure direct for highest sound quality pure direct is a special listening mode that causes pure direct block diagram rx-v3800 and rx-v1800 block diagram rx-v3800 and rx-v1800 hdmi input digital input analogue input hdmi receiver dsd signal pcm signal the signal to bypass all but the most basic audio circuitry it even turns off the display to prevent any chance of electrical noise interference you will hear the purest possible sound from all sources including usb and hdmi inputs low-jitter pll circuitry a low-jitter pll circuit in the preamplifier stage significantly reduces jitter from digital inputs for enhanced sound processing this is particularly effective in improving the sound quality of digital signals that are input via hdmi the addition of a vcxo digital clock circuit further reduces the possibility of jitter distortion dsp-z11 low-jitter pll and vcxo digital clock circuits dir low-jitter pll circuit input pc lpf vco pc lpf vcxo vcxo digital clock circuit output hdmi digital signal upscaling and deinterlacing this is a function that upscales analogue composite or s-video 480i/576i and component 480i/576i or 480p/576p signals to 1080i/720p hd signals or even 1080p full hd signals so they can be output digitally from an hdmi terminal and viewed at highest quality on high-definition displays in addition the analogue video signals deinterlaced from 480i/576i to 480p/576p also 1080i to 1080p in dsp-z11 are output at the hdmi terminal deep color 30/36 bit transmission dsp-z11 rx-v3800 rx-v1800 rx-v863 and rx-v663 these components support the latest hdmi 30 and 36-bit colour depths improved from the 24-bit depth of previous versions this deep color allows the rendering of billions of colours for far greater accuracy colours are so vivid they seem to jump off the screen with perfectly smooth tonal transitions and ultra-fine gradations between colours it also enables many times more shades of grey for higher contrast ratio 30 and 36-bit colour depth deep color right and current 24-bit depth left 30-bit colour depth consists of 4 times more shades of grey or more tek stop 1.00gs/s t ch1 zoom 10994 acqs 2.0x vert 20.0x horz tek stop 1.00gs/s t ch1 zoom 657 acqs 2.0x vert 20.0x

virtually no jitter dir decoder dsp dac output high picture quality 1080p-compatible hdmi all components the hdmi interface upgrades the transmission of standard enhanced and high-definition signals providing extremely high video quality hdmi inputs allow users to connect three high-definition sources such as blu-ray disc players and switch between them adc ram ram analogue signal pure direct on pure direct delivers two-channel audio sources such as cd and multi-channel audio sources including super audio cd and dvdaudio at levels of sound quality that will satisfy even the most dedicated music lovers also compatible with hd audio bitstream signals in dsp-z11 rx-v3800 rx-v1800 rx-v863 and rx-v663 x.v.colour dsp-z11 rx-v863 and rx-v663 when you use these components hdmi outputs to transmit video signals you enjoy spectacular colour performance one reason is that hdmi uses a new colour standard called x.v.colour which supports 1.8 times as many colours as previous hdtv signals this expanded range of colours means that hdtvs can display images with colours that are far more natural and vivid than ever before 100hz/120hz and 1080p/24hz refresh rates · high refresh rate 100hz/120hz the standard refresh rate frame rate for video displays is 50hz pal and 60hz ntsc recently however lcd tvs and monitors are being introduced that use a double refresh rate 100hz/120hz to prevent flicker and delay problems these components are capable of transmitting this high refresh rate signal via hdmi · low refresh rate 1080p/24hz blu-ray discs are mastered at 24 frames per second the same as 35mm movie film with 1080p resolution in order to make the most of this high quality 1080p/24hz compliant displays and players are being introduced these components are capable of transmitting the 1080p/24hz signal to ensure highest quality throughout the reproduction chain dsp-z11 high-quality audio parts 1 volume ic jrc njm1194 left burr-brown audio dac dsd1796 centre and op
