Ultra Low Jitter Clock System with Sampling Rate Converter (SC-LX90/LX81)

All of the Pioneer receivers use high-quality D/A converters, but to further ensure signal accuracy, they also feature a new clock system. After passing through the Low Jitter PLL and Crystal Oscillator circuits, the signal is upsampled to 192kHz by a Sampling Rate Converter. Controlled by the Ultra Low Jitter Clock, it undergoes D/A conversion in the best possible condition.

Full Band Phase Control

Full Band Phase Control is Pioneer's innovative solution for the phase shifts that occur in multi-channel speaker setups. Using advanced signal processing techniques, it corrects the phase irregularities that cause response deviations between the tweeter, midrange and woofer units, and also adjusts for the delays between speakers. This makes a big contribution to achieving the ideal surround sound in your home theatre.

original master recording. The receivers are also compatible with DTS-HD High Resolution Audio and Dolby Digital Plus.

Advanced MCACC (Multi-Channel ACoustic Calibration)

Designed to create a sound field ideal for surround sound reproduction, Advanced MCACC was achieved by adding time axis analysis, Standing Wave Control and New LR Symmetrical Acoustic Equaliser to the

original MCACC system. It compensates for the distance, sound pressure level and frequency response differences of each speaker, and makes numerous other adjustments as well. Time axis analysis allows the system to distinguish between direct sound and room reverberation, for more precise adjustment, while Standing Wave Control eliminates the boominess that these sound waves can cause. The New LR Symmetrical Acoustic Equaliser enhances stereo accuracy. All this is done automatically at the touch of a button.

Digital Video Converter,

Video Scaler and I/P Conversion

A high performance Digital Video Converter enables all analogue input video signals (composite, S-video and component) to be output via the HDMI terminal. The Video Scaler function performs upscaling of analogue video signals from 480i/p to a maximum of 1080p. The receivers also perform I/P Conversion that more n a t u r a l l y a n d s m o o t h l y

represents the curved parts of

images or letters that would otherwise have jagged edges. The result is that the receiver

transmits extremely high quality video signals, from both analogue and digital inputs, to your HDTV.

Home Media Gallery with DLNA Support

You can enjoy high-quality reproduction of moving pictures, music or image files stored on your PC simply by connecting your receiver to it or a LAN network. You also get the ability to access content quickly with various search options like genre and title. Home Media Gallery is designed to DLNA (Digital Living Network Alliance) guidelines, so the receivers can also play LAN-networked music files from other DLNA 1.0-compliant devices, regardless of the brand.

*The SC-LX90 is compatible with all moving picture, music and image files. The SC-LX81/LX71 are compatible with music and jpeg image files, and the VSX-LX70 with music files only.

Jitter-free HDMI Transmission

All LX receivers and amplifier are equipped with HDMI input/output terminals that provide digital transmission of the highest quality video and audio signals from Blu-ray Discs. HDMI offers the advantages of Deep Colour and x.v.Colour, for extremely natural, beautiful images based on 30/36-bit colour information. It also has a Jitter Reduction Circuit that uses a high precision PLL to reduce the clock jitter that can occur during HDMI transmission, ensuring maximum clarity.
