High quality sound With discrete circuit technology, the power amplifier provides identical quality for all 9-channels (190 Watts x 9-channels) For optimum realism and stunning dynamic range, the power amplifier section features discrete power devices (not integrated circuitry). By using high current, high power discrete power devices, the amplifier is able to easily drive high quality speakers. Dolby Atmos (v p. 317) This unit is equipped with a decoder that supports Dolby Atmos, a completely new audio format. The placement or movement of sound is accurately reproduced by the addition of overhead speakers, enabling you to experience an incredibly natural and realistic surround sound field. Audyssey DSX® (v p. 178) This unit is equipped with Audyssey DSX® processor. By connecting front height speakers to this unit and playing back with Audyssey DSX® processing you can experience a more vertically expansive front soundstage. By connecting two front wide speakers, you can experience a wider and more expanded front soundstage. Audyssey LFC™ (Low Frequency Containment) (v p. 177) Audyssey LFC™ solves the problem of low frequency sounds disturbing people in neighboring rooms or apartments. Audyssey LFC™ dynamically monitors the audio content and removes the low frequencies that pass through walls, floors and ceilings. It then applies psychoacoustic processing to restore the perception of low bass for listeners in the room. The result is great sound that no longer disturbs the neighbors. Discrete subwoofers and Audyssey Sub EQ HT™ (v p. 201) The unit has two subwoofer output capability and can adjust the level and delay for each subwoofer individually. Audyssey Sub EQ HT™ makes the integration seamless by first compensating for any level and delay differences between the two subwoofers and then applying Audyssey MultEQ® XT32 to both subwoofers together for improved deep bass response and detail. DTS Neo:X (v p. 320) This technology enables the playback of 2-channel source audio or 7.1/5.1 multi-channel source audio through a maximum 11.1-channel speakers, achieving an even broader soundstage. Denon’s unique high quality playback technology “Denon Link HD” (v p. 63) This unit is equipped with our exclusive “Denon Link HD” technology. When connected to a Denon disc player that has Denon Link HD, the sound localization becomes more precise, with increased detail and definition. The system works by carrying the critical clock timing signals via the dedicated Denon Link HD connection, minimizing the jitter caused by conventional digital connections. This effect can be applied to an audio source of any media from a Blu-ray disc player.
