It delivers 150 watts per channel--more than enough power for the largest of rooms and the most demanding of speakers. With seven HDMI inputs and three HDMI outputs, the receiver lets you enjoy high-definition audio and video from a range of devices in multiple rooms. The AVR-4520CI incorporates true multi-zone HDMI audio/video distribution with its HDMI matrix-switching functionality.

<b>Audyssey Platinum</b>
The AVR-X4000 features Audyssey Platinum, our most robust level of Audyssey support with Audyssey MultEQ XT32, Audyssey Dynamic Volume, Audyssey Dynamic EQ, Audyssey DSX, Audyssey Sub EQ HT, Audyssey LFC, and Audyssey Pro. Audyssey MultEQ XT32 harnesses the power of sophisticated DSP processing, measures the acoustic output of the speakers and subwoofers, and generates multiple digital EQ filters with 256 times the resolution of standard MultEQ. This provides the smoothest, most natural tonal balance in virtually any room. Audyssey DSX offers the option of front wide and front height speakers which are placed to the left and right or above the main front speakers to broaden the width and/or height of the soundstage, making the audio experience more impressive, engaging, and believable. Audyssey Dynamic Volume senses the impending arrival of very loud sounds and automatically reduces the difference between normal and extra-loud programming. Audyssey Dynamic EQ automatically adjusts subwoofer and surround speaker levels for maximum performance at any playback volume. Audyssey Sub EQ HT provides individual tailoring for dual subwoofer setups. Audyssey LFC (Low Frequency Containment) provides a full range tonal balance for late-night listening that minimizes the intrusion of deep bass content into adjacent rooms or spaces. The AVR-X4000 is also Audyssey Pro Installer ready.

<b>Superior Surround Sound and 3D Pass-Through Technology</b>

<b>4K Upscaling for Pristine Picture Quality</b>
