Advanced MCACC
(Multi-Channel ACoustic Calibration)
You will enjoy maximum
performance from your
Blu-ray Discs and DVDs
thanks to full support for
the Dolby TrueHD and
DT S-HD Mas ter Aud io
lossless surround sound
formats. The sound of
m o v i e s a n d m u s i c i s
completely faithful to the
original master recording. The receivers are also compatible
with DTS-HD High Resolution Audio and Dolby Digital Plus.
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.
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.
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.
Home Media Gallery with DLNA Support
N
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.
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.

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

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.
