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.

Stream with DLNA
DLNA is widely supported on PCs, laptops, smartphones and other devices. This receiver being DLNA certified, you can easily stream audio from such a device using your home network.
The remote of the future
iControlAV2 is our 2nd-generation app that lets you control all important receiver functions from your smartphone or tablet. Control playback, select an input, adjust listening modes and change sound balance and emphasis from one app. iOS + Android.

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.
