Features
Advanced Direct Energy design
This receiver offers a new advancement in discrete 
design unique to Pioneer for high-power drivability, low 
distortion and stable imaging. Through a circuit design 
that minimizes the energy loss of the amplifier for each of 
the channels, this receiver generates equal amplifier 
power to all channels, eliminating the possibility of one 
channel dominating a particular sound field.
Easy setup using Advanced MCACC 
The Auto MCACC Setup provides a quick but accurate 
surround sound setup, which includes the advanced 
features of Professional Acoustic Calibration EQ. This 
innovative technology measures the reverb 
characteristics of your listening area, allowing you to 
customize your system calibration with the help of a 
graphical output that can be displayed on-screen or 
using computer. With the additional benefits of 
numerous MCACC preset memories, standing wave 
control and microphone measurements from a series of 
reference points, your home theater experience can be 
truly customized for optimal surround sound.
THX Select2 Plus certified design
This receiver bears the THX Select2 Plus logo, which 
means it has passed a rigorous series of quality and 
performance tests covering every aspect of the product. 
This includes testing of pre-amplifier and power amplifier 
performance and operation, and hundreds of other 
parameters in both the digital and analog domain, 
making your home theater experience as faithful as 
possible to what the director intended. 
Dolby Digital and DTS decoding, including Dolby 
Digital EX, Dolby Pro Logic IIx, DTS 96/24, DTS-ES, Dolby 
Digital Plus, Dolby TrueHD, DTS-EXPRESS and DTS-HD 
Master Audio
Dolby Digital and DTS decoding brings theater sound 
right into your home with up to six channels of surround 
sound, including a special LFE (Low Frequency Effects) 
channel for deep, realistic sound effects.
The built-in Dolby Pro Logic IIx and DTS Neo:6 decoders 
not only provide full surround sound decoding for Dolby 
Surround sources, but will also generate convincing 
surround sound for any stereo source.
Also, with the addition of a surround back speaker, you 
can take advantage of the built-in Dolby Digital EX and 
DTS-ES decoders for six-channel surround sound.
Furthermore, Dolby Digital Plus and Dolby TrueHD, 
which are designed for the next-generation high-
definition media such as Blu-ray Disc and HD DVD, 
support up to 7.1 channels and 8 channels respectively.
DTS-EXPRESS is a low-bitrate encoding technology 
supporting up to 5.1 channels, with fixed data transfer 
rates ranging from 24 kbps to 256 kbps (this encoding is 
available only when signals are delivered to this receiver 
as primary audio).
DTS-HD Master Audio delivers audio signals to listeners 
without any loss of data with its high transfer rates.
Phase Control
The Phase Control technology incorporated into this 
receiver’s design provides coherent sound reproduction 
through the use of phase matching for an optimal sound 
image at your listening position.
Sound Retriever
The Sound Retriever feature employs DSP technology to 
restore sound pressure and smooth jagged artifacts left 
over after compression. This helps bring CD quality 
sound back to WMA and MP3 audio files and achieves a 
richer sense of presence when playing Dolby Digital, DTS 
or WMA 9 Pro audio formats recorded in multiple 
channels on DVDs and other discs.
Front Stage Surround Advance
With the Front Stage Surround Advance feature, you can 
enjoy seamless, natural surround sound effects using 
only the front speakers, without deteriorating the quality 
of the original sound.
Auto Level Control
When the source is played in Auto level control mode 
(ALC), this receiver automatically equalizes the playback 
sound level according to the variation in recording levels. 
HDMI and digital video conversion
This receiver is compatible with the HDMI digital video 
format, providing you with high-definition digital video/
audio via a single cable. 
High-quality sound formats such as DTS-HD and Dolby 
TrueHD are supported while this receiver is also 
compatible with the Deep Color feature. You can operate 
this receiver in synchronization with your Pioneer 
component that supports the KURO LINK function by 
connecting your component to this receiver via HDMI. 
Also, the built-in digital video converter of this receiver 
makes both de-interlacing and up-scaling possible, and 
analog video signals being input are converted and 
output as digital video signals at the HDMI terminal.
