High quality sound

Featuring discrete high-current power amplifiers on all channels, this unit delivers 140 W of power per channel (8 Ω/ohms, 20 Hz - 20 kHz, T.H.D.: 0.05 %, 2ch. driven). With low impedance driver capability, it offers operational stability with a wide range of speakers for balanced, quality sound.

Auto Eco Mode adjusts power output to speakers based on volume level and on-screen eco meter, providing power consumption reduction in real-time without sacrificing superb Marantz sound.

Immerse yourself in evenly distributed, accurate bass. Featuring up to four subwoofer outputs to smooth out low frequencies and provide better dispersion. No audible peaks or dips - just powerful, room-filling bass.

This unit uses a high-speed current feedback amplifier circuit for its preamplifier so that signals from a Blu-ray Disc player and other equipment that support high-definition audio formats can be amplified with high fidelity. The high-speed current feedback amplifier also reproduces a natural sound space.

This unit is equipped with a decoder that supports Dolby Atmos 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.

Speaker Virtualizer enables you to access a more immersive entertainment experience from traditional channel based speaker layouts through digital signal processing including Dolby Atmos height virtualization and surround virtualization.

This unit is equipped with the DTS:X decoder technology. DTS:X brings the home theater experience to new heights with its immersive object based audio technology which removes the bounds of channels. The flexibility of objects allows for sound to be scaled large or small and moved around the room with greater accuracy than ever before leading to a richer immersive audio experience.

DTS Virtual:X technology features DTS’s proprietary virtual height and virtual surround processing to deliver an immersive sound experience from any type of input source (stereo to 7.1.4 channel) and speaker configuration.

This IMAX Enhanced product have met stringent performance standards established by IMAX and DTS in order to create a consistent and higher bar for sound performance. DTS has developed a special method for reproducing an IMAX signature sound experience in the consumer’s home. This method combines a unique conversion process for IMAX theatrical audio mixes utilizing an enhanced DTS codec technology. The IMAX theatrical audio format with point source surround speakers closely matches the speaker configuration most consumers have in their homes today. Coupled with DTS audio technology, IMAX Enhanced audio products will ensure the best and most accurate audio reproduction over 5.1 or more speaker channels.

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.

The unit has four 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 four subwoofers and then applying Audyssey MultEQ_® XT32 to four subwoofers together for improved deep bass response and detail.

The interaction between your sound system and the physical layout of your room has a huge impact on sound quality. Dirac Live_® Room Correction applies state-of-the-art, patented algorithms to analyze and digitally reduce room impact and enhance speaker performance. Dirac Live delivers a larger sweet spot, accurate staging, clarity, voice intelligibility, and a deeper, tighter bass not otherwise possible. Fully tunable to your preference.

Dirac Live Bass Control is a technology to manage low-frequency channel routing from the signal to the playback channels (speakers) of your audio device. Additionally, with full control over the device’s channel and frequency routing and output, the Dirac Live Room Correction technology is significantly augmented. In particular systems with multiple subwoofers will see a substantially improved room correction and bass performance.

This unit is equipped with an AURO-3D decoder.
With AURO-3D, Front Height (FHL + FHR), Surround Height (SHL + SHR) and Top Surround (TS/optional) are added to a conventional 5.1-channel system to achieve a natural and realistic sound field that is three-dimensional and fully immersive.

You will be able to fully enjoy AURO-3D playback if you properly place the speakers for AURO-3D.
