Impressive value already at entry level
In addition to digital TV and Blu-ray, one nowadays usually has other HD video sources - such as a game console, a streaming box or a streaming stick. It is reassuring to know that even the affordable VSX-531D has four HDMI ports that can even transmit UltraHD footage to the TV or projector. Of course, via HDMI the sound can also be in high resolution. The HD multichannel formats from Dolby and dts are also decoded by the VSX-531D and precisely adapted to your individual room acoustics, loudspeaker equipment and setup using Pioneer's proprietary MCACC automatic calibration.
If you prefer to enjoy music instead of a movie, you can also use your smart phone or tablet instead of the usual analogue or digital connectable players. Simply start your favourite music app and connect your device wirelessly to the integrated Bluetooth input of the VSX-531D. A USB port on the front panel provides the mobile device with current as needed and you can also optionally play MP3, WMA and AAC music files directly from a memory stick. And do not be surprised when even older, heavily data-reduced files suddenly sound amazingly fresh and natural. Pioneer has gained decades of experience in the reconstruction of lost signal components, which has flowed into the "Advanced Sound Retriever" playback program.
Energy efficient settings
Use the ECO Modes to save energy. ECO Mode 1 is suitable for playing CD's, 2 channel audio files and internet radio. The more energy efficient ECO Mode 2 also works with movies, live concerts and other surround content.
Easy USB access
The AV receiver has an easily accessible front USB terminal so you can quickly play your favourite music tracks. It supports all kinds of audio formats, such as MP3, WMA and AAC. It can also be used to charge connected devices.
Enjoy uncompressed HD audio
The AV receiver supports the latest Dolby TrueHD and DTS-HD Master Audio surround soundtracks, so you can enjoy uncompressed, high-definition multichannel audio from Blu-ray discs, as well as from other media.
Smarter room calibration
Often, speakers for surround sound can't be ideally positioned. MCACC analyses the existing sound field using a microphone (included), just like a sound professional. It then adjusts each speaker's virtual size, level, distance, and response to precision-tune the system to your room.
