7.1 Channel HDMI 3D AV Receiver with HD Audio, iPod/iPhone/iPad Digital Direct, AirPlay, DLNA and Internet Radio


The receiver of today.

The VSX-921 meets all the popular AV receiver needs: 7.1 surround sound in HD, and a digital connection with your iPod, iPhone or iPad without dock. Additionally, it adds in easy-to-operate worldwide internet radio and network streaming via DLNA or Apple Airplay when you connect via LAN (adapter for wireless LAN available). LPCM, WAV, FLAC and other lossless formats are supported.

Compatible (free) smartphone/tablet apps include the advanced remote control app iControlAV2 and Air Jam, a Bluetooth-based social app.

The VSX-921 has 6 HD inputs including 4 x HDMI.

Intelligent speaker calibration

Surround speakers can hardly be ideally positioned. MCACC therefore analyses the existing sound field using a microphone (included), just like a sound professional, and adjusts the sound timings to precision-tune the system to your room.

Digital Direct connection with your iPod, iPhone or iPad

No need for a dock – you can connect your Apple device directly to the receiver. Thanks to the digital connection, you get the best possible audio quality (further enhanced by the Advanced Sound Retriever). Furthermore you can view photos and videos on, and stream apps like YouTube to your TV.

Stream with AirPlay

Apple's AirPlay lets you stream music from any compatible device connected to your home network. This means you can easily enjoy your iTunes music library through your AV receiver.

Music listening made social

Air Jam is a Bluetooth-based app that lets a group of people connect with their iPhones, iPod Touch or iPads and add their songs to the receiver playlist. Participants can see which song was, is or will be playing – a great way to share and discover tunes. Requires iOS 4.2 with iPhone 4/3GS/3G, iPad or iPod touch (2nd gen. or higher).

Less jitter, better audio

Transmission via HDMI can cause clock jitter, causing sound distortion during the D/A conversion. PQLS “speed synchronises” the digital audio data between the receiver and your matching Pioneer Blu-ray player, reducing the jitter. The result is clear, rich and precise audio.

Image optimised for you

Advanced Video Adjust optimises the video signal according to your type of screen or projector. Based on MCACC calibration data, it also adjusts image quality to your distance from the screen.

Intuitive setup and operation

With the receiver connected to your home network, AVNavigator software makes installing a breeze. Wiring Navi guides you in making the connections with speakers and other devices, and updates the receiver with the appropriate settings, while the interactive manual lets you intuitively explore every feature. AVNavigator is also backed by a free iPad app.
