Pioneer need little to no introduction to the world of premium audio, having been a market leader in a multitude of aspects within the audio industry for many years. Pioneer's range of AV receivers are designed and engineered to go beyond that of what is typically expected from boxes at their price-point. With a stand-by consumption of only 0.1 watts when enabled, the ECO mode is an appealing feature, as the setting offers all of the convenient features of current receivers, including network standby and HDMI CEC support while keeping your electricity bill down and being better for the environment.

The VSX-523 is fully equipped for optimal performance in regards to both sound and picture. Compatible with the most state of the art HD audio formats, such as Dolby TrueHD and DTS-HD Master Audio, the soundtracks to your Blu-Ray films are dynamic, immersive and life-like. This receiver also includes all of the Dolby and DTS formats most suited to online streaming services like Netflix and Vudu. 

Multi-Channel Acoustic Calibration System, an optimised multi-channel listening experience designed specifically by Pioneer can also be found within the VSX-523. This enhances the sound by measuring every speaker 's connection, making a note of its size and distance from the listening points, sound levels and acoustic timbre within the room. The receiver then calibrates, customises and maximises the performance of your home theatre system.
