Pioneer VSX-S520D – Spectacular AV receiver

The Pioneer VSX-S520D is a do-it-all AV receiver that is half the size but fully featured, including a DAB radio and network streaming.

Compact Design
The Pioneer VSX-S520D is only 70mm height, which is half the height of most AV receivers. This means it can go where others can’t and, more importantly, it can stay cool. It also happens to be one of the most aesthetically pleasing AV receivers on the market. For a clean look, a clear display is flanked by only a few controls.

Performer with a punch
Despite its small size, the VSX-S520D makes no sacrifices in terms of power. 80 watts per channel (at 4 ohms) is sufficient for all but the largest rooms.The power is supplied by a Class D amplifier that is not only powerful but also quiet, making it ideal for this small Pioneer. A unique feature of this AV receiver is the powered subwoofer output. This allows you to use a passive subwoofer, though an active subwoofer can also be connected via the standard RCA sub output.

When using Dolby Atmos-enabled speakers, high directivity sound from the unit reflects off the ceiling, while low directivity sound directly reaches the ears. The different pathways cause a phase shift, making the sound feel uncomfortable. The Reflex Optimizer which uses the Phase Control technology adjusts this shift, and improves the localisation of the sound image by aligning the frequencies with those of the floor speakers, creating the ideal reproduction environment.

Google Cast, AirPlay, and Bluetooth are all options
With Googlecast and AirPlay built in, it’s simple to stream music from your smartphone or tablet. Connect wirelessly and use the Google (Android) or iTunes (Apple) operating systems to stream your stored music or favorite music services. Bluetooth wireless music streaming is also available for universal compatibility, including many laptops and PCs.
Wi-Fi, Tidal, Spotify, and Internet radio are all available for a complete networking experience.
Wi-Fi, Internet radio, Tidal, and Spotify are also included with the VSXS520D. Simply connect to your home network via Ethernet or Wi-Fi to gain access to thousands of Internet radio sites as well as subscription services like Spotify Connect and Tidal.

FlareConnect powered by Blackfire allows you to add a wireless speaker
It is possible to create a multi-room speaker system – wirelessly, using the latest FlareConnect by Blackfire technology. Simply add compatible Pioneer wireless speakers to another room to mirror what’s playing on the main system.
DAB (Digital Audio Broadcasting)
The Pioneer VSXS520D is the only AV receiver in its class featuring a built-in DAB digital radio. This allows you access to a large number of stations as well as the convenience of hiss-free digital radio. There’s also an FM tuner for listening to local and national stations on the analogue radio network, in addition to the DAB radio. Photo: Pioneer
