9 channel Amplifier
Marantz SR6011 features 9 channel power amplifier. It is rated at 110 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.
- Current Feedback Topology: Marantz SR6011 features Current Feedback Topology which is a well known, Marantz’ original circuit technology. The Current Feedback amplifier technology fits perfectly with the high requirements set for Super Audio software providing wide-bandwidth, high-speed reproduction. The impedance at the Current Feedback point is limited resulting in a very low phase shift. Marantz receivers and amplifiers equipped with Current Feedback can keep the phase compensation via Negative FeedBack (NFB) to a minimum, resulting in high through-rate, excellent transient response and superb sonic transparency for the full bandwidth. Unlike conventional Voltage Feedback amplification, the Current Feedback amplification makes the power amplifier in-sensitive to difficult loudspeaker loads.
- HDAM (Hyper Dynamic Amplifier Module): Marantz SR6011 features exclusive Marantz HDAM (Hyper Dynamic Amplifier Module) technology found on their Reference Series components. Marantz developed its own discrete circuit boards to replace standard IC's. These HDAM's consist of discrete surface mount components with short mirror image L/R signal paths. Those devices are doing exactly the same thing as the Op-Amps, but outperform the regular IC Op-amps dramatically in terms of the Slew Rate and reduced noise level, resulting in a much more dynamic, accurate and detailed sound. Over the years Marantz developed different types of the HDAM to improve quality and to fit to the special requirements of a product category like CD or amplifier.
Marantz SR6011's 9 channel amplifier can be assigned for different speaker configurations.
- Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
- 5.2.2, 5.2.4, 7.2.2 with internal amplifier.
- 7.2.4 with addition of external 2 channel amplifier.
- DTS:X Configurations: The speaker configurations for DTS:X are the same as for Dolby Atmos:
- 5.2.2, 5.2.4, 7.2.2 with internal amplifier.
- 7.2.4 with addition of external 2 channel amplifier.
- Configurations without height channels: There are also other speaker configurations available which do not include height channels:
- 5.2, 7.2 with internal amplifier.
- 2-ch Bi-Amp: Marantz SR6011 allows you to bi-amp up to 2 main channels simultaneously. During bi-amplification two amplifiers are used for one speaker. One amplifier powers the midrange and tweeter section of the speaker and another amplifier powers the low frequency woofers. Each amplifier is less loaded and performs better. In order to use this feature speakers must have 2 pairs of connectors.
Marantz SR6011 supports Dolby Atmos. It is a cinematic audio format in which sounds exist as individual entities, called audio objects. In Dolby Atmos, any sound can exist as an independent audio object, free of channel restrictions. They can be precisely placed and moved anywhere in your room, including overhead, to flow above and around you in three-dimensional space. Through the use of audio objects, overhead sound, and all the richness, clarity, and power of Dolby sound, Dolby Atmos turns your room into an amazing place for entertainment. The format supports up to 128 simultaneous independent audio objects in a mix for rich, realistic, and breathtaking sound. It recreates the director's original concept through descriptive metadata to provide customized playback for home theater and delivers sounds above you through overhead speakers, special upward-firing Dolby Atmos speakers, or a Dolby Atmos enabled sound bar.
- Dolby Surround Upmixer: If the content is not mixed in Dolby Atmos then the Dolby surround upmixer will expand the audio to all channels including ceiling speakers. The upmixer has replaced the Dolby Pro Logic II family with improved upmixing algorithms.
Marantz SR6011 supports DTS:X. A technique used in DTS:X is similar to the one used in Dolby Atmos. Instead of a fixed number of channels, DTS:X defines object locations from the listener in polar coordinates. An a/v receiver then dynamically renders sound according to the current speaker configuration. The speaker layout employed by DTS:X is the sum of Dolby Atmos and Auro-3D. It has standard 7.1 channel base layer, a 5 channel height layer above the base layer on the front and side walls, and 3 rows of speakers on the ceiling.
- DTS Neural:X: DTS Neural:X is an advanced upmixer that can take non DTS:X content and upmix it to the DTS:X speaker layout. It has replaced the DTS Neo family with improved flexibility.
- DTS Dialog Control: This function adjusts the dialog levels during playback of the DTS:X stream. It allows you to separately increase the dialog levels in contrast with the background sound and hear dialog easily even under noisy circumstances.
- Audyssey: Marantz SR6011 comes with Audyssey Dynamic EQ, Dynamic Volume, LFC and Sub EQ HT.
- Dynamic EQ: selects the best possible frequency response and surround volume levels moment-by-moment. This ensures that the bass response, tonal balance and surround impression remain constant despite changes in volume. This is the first technology that carefully combines information from incoming source levels with actual output sound levels in the room, a pre-requisite for delivering a dynamic volume solution.
- Dynamic Volume: Your Listening experience can be greatly diminished when there are significant shifts in volume between television programs, commercials and within the program material itself. When this happens you must constantly adjust the volume to maintain your desired listening level. Audyssey Dynamic Volume monitors the volume of program material moment-by-moment and automatically adjusts it, maintaining the desired listening level for all content while optimizing the dynamic range to preserve impact.
- LFC (Low Frequency Containment): While high frequencies are easily stopped by walls low frequencies pass right through. After identifying the frequency range that most readily passes through walls Audyssey developed a technique, called Audyssey LFC (Low Frequency Containment) that reduses the volume at those frequencies and applies psychoacoustic processing to restore the perception of low bass for listeners in the room. The result is no more angry neighbors and no loss of enjoyment for listeners.
- Sub EQ HT: Placing two subwoofers in the room can cause problems, they can create standing waves or even cancel each other out resulting in even less bass than a single sub can produce. Audyssey Sub EQ HT allows two subwoofers to be properly used in a home theater system. The process is automated and takes only a few minutes. The result is rich, full bass for everyone in the room.
- MDAX2: Compressed music enhancement in Marantz SR6011 is done by Marantz’ MDAX2 technology. The use of compressed audio files like MP3, Windows Media™ Audio or AAC is getting more and more popular. The audio quality of these compressed files however is less than the original lossless files that are on a CD, especially lacking the higher frequencies and affecting the lower frequencies which make the audio image less wide and deep. The Marantz Digital Audio Expander 2, also called M-DAX2, recalculates the outputted frequency range. This enables you to get a more detailed and clearer sound.
Marantz SR6011 comes with Audyssey MultEQ XT32 room correction system and includes the calibration microphone. It also supports Audyssey App.
- Audyssey Room Calibration: Audyssey is an acoustic measurement technology which automatically restores the acoustic distortion caused by the acoustic behaviour of a room with only a push on a button. Audyssey equalization provides an clear, accurate, natural sound with voices and dialog that become focused and intelligible, restoring the musical balance. Musical instruments and sound effects become precisely localized and the surround soundstage is made seamless and enveloping.
Marantz SR6011 features 8 HDMI inputs. It has 3 outputs: 2 for MAIN and 1 for ZONE2.
- 4K/60Hz Passthrough: All inputs pass up to 4K 50/60Hz 4:4:4 video signal.
- 4K Upscaling: Marantz SR6011 can upscale up to 4K 50/60Hz 4:4:4 from HDMI and analog sources.
- Analog To HDMI Upconversion: The a/v receiver supports video upconversion, so you can connect your analog Component and Composite video sources and Marantz SR6011 will output them via HDMI. This means that you will need only one HDMI cable to connect to your TV.
- BT.2020 Color Space: BT.2020 or Rec. 2020 is a color standard which delivers a wider color gamut compared to Rec. 709. It covers approximately 75% of the total visual spectrum while the Rec. 709 covers only 35%.
- HDCP 2.2 Copy Protection: All inputs and outputs are HDCP 2.2 compliant which is a requirement for 4K/HDR copy-protected content transmission.
- 3D Ready: Marantz SR6011 is able to pass 3D video through HDMI.
HDR (High Dynamic Range)
Marantz SR6011 supports HDR (high dynamic range) video formats such as HDR10, Dolby Vision and Hybrid Log-Gamma. High dynamic range video has greater dynamic range than standard dynamic range (SDR) video with brighter whites and deeper blacks. The result is greater contrast and more details in dark and bright areas, better color and depth.
- HDR10: HDR10 uses the wide-gamut Rec. 2020 color space. It sends static metadata via video stream to the TV which calibrates its screen brightness and color according to that. HDR10 supports 10-bit color which corresponds to 1024 shades of the primary RGB colors. It is technically limited to a maximum of 10,000 nits peak brightness, however common HDR10 contents are mastered with peak brightness from 1,000 to 4,000 nits.
- Dolby Vision: Dolby Vision is a set of technologies developed by Dolby Laboratories for high dynamic range (HDR) video. It covers content creation, distribution, and playback. Like HDR10+, it includes dynamic metadata that are used to adjust and optimize each frame of the HDR video to the consumer display's capabilities in a way specified by the content creator. Dolby Vision allows for a maximum resolution of 8K up to 12-bit color depth, maximum peak brightness of 10,000 nits and a color gamut up to Rec. 2020. It uses Dolby's proprietary dynamic metadata defined in SMPTE ST 2094-10.
- Hybrid Log-Gamma (HLG): The Hybrid Log-Gamma (HLG) is a transfer function developed mainly for HDR live video feed and over-the-air broadcasts. It is an HDR format that uses BT.2020 color primaries and a bitdepth of 10-bit. It is backward compatible with the transfer function of SDR and is designed to be better-suited for television broadcasting, where the metadata required for other HDR formats is not backward compatible with non-HDR displays. HLG defines a non-linear optical-electro transfer function, in which the lower half of the signal values use a gamma curve and the upper half of the signal values use a logarithmic curve.
Marantz SR6011 offers multi-zone playback which allows you to play different input sources in 2 different rooms.
- Powered Zone 2: You can use the unit's 2 amplifier channels by connecting Zone 2 speakers directly to the speaker terminals. The remaining 7 channels will be left for main zone amplification.
- HDMI Output: Marantz SR6011 offers HDMI output for Zone 2. This means that it can send two different HDMI signals to two displays.
- Audio Pre Output: If you have a dedicated power amplifier for Zone 2 you can connect it to the a/v receiver via pre outs and control volume from the a/v receiver.
Inputs and Outputs
- 7.1 Multichannel Input: In case you have a high quality Blu-Ray or a DVD player with multichannel analog outputs you may connect it to a 7.1 multichannel analog inputs of the a/v receiver and use high quality DACs of the player instead of the ones in the a/v receiver.
- Analog Pre-Outs: Marantz SR6011 has 11.2 preamplifier outputs which allow you to connect the a/v receiver to the external power amplifier. You may want to use a high quality external amplifier for certain channels, usually for front L/R and center, and use the a/v receiver to power the rest. Also, Marantz SR6011 has 11 channel processing but has only 9 channel amplifier, so it needs the external amplifier connected to the analog pre-outs in order to reach the maximum speaker configuration.
- Analog Line Inputs: There are 6 line inputs for analog audio connection.
- Digital Inputs and Outputs: 1 optical input, 2 optical outputs and 2 coaxial inputs are available for digital audio connection.
- Headphone Output: There is a 6.3 mm (1/4") headphone output jack on the front panel.
- Inputs: 8 (1 front) Outputs: 3 (2 for MAIN, 1 for ZONE2)
8K Inputs: 0
- Composite Video: Connect you VCR, Laserdisc player and other old video equipment with composite video cables.
- Inputs: 4 Outputs: 1
- Component Video: Component video connection gives you the higher quality video compared to the composite video connection. So in case your old DVD player and other equipment do not have an HDMI output but have Component video output use this connection over the composite one. Marantz SR6011 supports up to 1080p resolution on Component video connectors.
- Inputs: 2 Outputs: 1
