for perfect phase harmony.
Pioneer's phase control technology, developed to eliminate
bass phasing problems in order to improve multi-channel
sound fields, has taken another step forward with Full Band
Phase Control. This innovative function corrects phase
irregularities that occur in multi-unit speakers. Phase
irregularities cause group delay, the delay of sound between
the tweeter, midrange and woofer units. Full Band Phase

Advanced MCACC automatically
achieves the ideal surround space.
Advanced MCACC is the latest version of Pioneer's original
MCACC (Multi-Channel Acoustic Calibration system). Designed
to create a sound field ideal for surround sound reproduction,
it was achieved by adding time axis analysis, Standing Wave
Control and New LR Symmetrical Acoustic Equaliser to the
original MCACC system. It compensates for 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.

HDMI Control for convenient operation.
HDMI Control is a user-friendly function that lets you
operate your home theatre system with a single remote
control. By connecting the receiver to a compatible Pioneer
PDP or the Blu-Ray Disc player via an HDMI cable, you can
control the basic operations of these components with the
PDP's remote control.
HDMI 1.3a provides Deep Colour
for finer colour reproduction.
The latest HDMI 1.3a digital interface supports the full
digital transmission of highly detailed 1080p high definition
video and 7.1-channel 24.5Mpbs audio data via a single cable.
It also provides the benefits of Deep Colour, which supports
30- and 36-bit RGB (previously 24-bit), permitting much finer
colour reproduction. With HDMI 1.3a, you enjoy more natural
and beautiful video images.
Advanced technology for high picture
quality: 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 naturally and smoothly represents the curved parts
of images or letters that would
otherwise have jagged edges.
The result is that the receiver

* Depending on the source device specifications, it may be impossible to output video and
audio to a TV via HDMI connection.

Pioneer's Pursuit of Perfection
Multi-channel sound can cause problemsÉ.
From bass to treble, from subwoofers and rear speakers,
you hear the sound that the creator intended you to hear.
This is the ideal of multi-channel audio. But various
factors, such as speaker configuration and the listening
environment, generally prevent the ideal from being
achieved. Pioneer has developed Full Band Phase Control
and Advanced MCACC to resolve these problems.
