The AVR-4520 A/V receiver features all-channel discrete circuitry for the power amplifiers of 9 channels. It is also endowed with?symmetrical monolithic construction where the power transformer is placed at the centre and the power amp blocks are at each side to?achieve separation for all channels and an ideal weight balance that together deliver uncompromised sound quality. In addition,?the DDSC-HD32 (Dynamic Discrete Surround Circuit), that uses the latest DSP for processing surround sound for up to 11.2 channels at?32-bit precision and 32-bit/192 kHz D/A converters for all channels, is sure to envelope you in an exciting sound space of a sort you have?never before experienced. When you add an external power amp, the expressive power of this remarkable sound space is expanded?to all 11.2 channels, the AVR-4520?s maximum potential. The AVR-4520 includes Audyssey MultEQ XT32 and Audyssey Sub EQ HTTM?that measure the performance of your speakers and the acoustics of your listening room to produce the best sound possible, as well as?support for 4K video (3840 x 2160), AirPlay, Zone-compliant HDMI output and other advanced features to give you the impeccable quality?of sound and ease of operation you expect from a flagship A/V receiver. |
