Product Details

Pioneer 5.1 Channel 3D Ready AV Receiver, Model VSX521K

Introducing the Pioneer VSX-521-K AV Receiver

With clean, compelling lines, the VSX-521 has been streamlined to look as elegant, modern and state-of-the-art as the technology inside. Technology designed to serve one singular purpose: to get you closer than ever before to the artist's true intent.

Unleash your Smartphone's Music with Bluetooth®
The VSX-521 is fully ready for wireless Bluetooth audio from virtually any A2DP profile Bluetooth device, including iPod®, iPhone®, iPad®, smartphones, laptops, etc. With the Pioneer AS-BT200 Bluetooth adapter, you can untether yourself from cables and inputs. And you'll enjoy near cd-quality with Sound Retriever AIR technology, created specifically to enhance Bluetooth audio.

Ultimate Sound Control
Of course the VSX-521 supports the latest high-definition audio formats, Dolby® TrueHD and DTS-HD® Master Audio to give your Blu-ray Disc® soundtracks unsurpassed audio quality. But Pioneer also includes all of the Dolby and DTS surround formats best suited for the wide variety of entertainment sources, including the newest Dolby Pro Logic IIz height channel. New for this year, the VSX-521 features Pioneer's exclusive Multi-Channel Acoustic Calibration system (MCACC), providing a near studio-quality, multi-channel listening experience customized specifically to your listening environment. An included microphone measures every speaker's connection, and notes its size, distance from the listening point, sound levels and timbre to calibrate and maximize performance specifically for your room. All you have to do is sit back and let it happen. Even compressed audio such as WMA, MP3 and AAC is enhanced with another Pioneer exclusive, Advanced Sound Retriever, by filling in areas where minute details were left out during the compression process. And since the only thing that should shock you is how good it sounds, there's also an Auto Level Control that eliminates jarring volume changes between your favorite songs, albums and audio sources by equalizing volume differences between portable audio tracks or television programming.

Ready for 3D?
You are with the Latest HDMI® Technology All of Pioneer's newest receivers support the latest HDMI 1.4a specification. So not only do you get the most out of your existing movies and music, with the VSX-521 you're prepared for the next generation of 3D video content. With 4 HDMI inputs, you've got plenty of connectivity options for the growing number of high-definition sources available. All Pioneer receivers also offer advanced HDMI conveniences like Audio Return Channel and HDMI Standby Through.

On-Screen Display
The VSX-521 features an intuitive on-screen menu for use with the included remote, so you can make guided adjustments to your home theater sound.
