7 channel Amplifier
Marantz Slimline NR1608 features 7 channel power amplifier. It is rated at 50 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and is able to drive 4 ohm speakers.
Marantz Slimline NR1608's 7 channel amplifier can be assigned for different speaker configurations.
- Dolby Atmos Configurations: The following speaker configurations are supported for Dolby Atmos:
- 5.2.2 with internal amplifier.
- DTS:X Configurations: The speaker configurations for DTS:X are the same as for Dolby Atmos:
- 5.2.2 with internal 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 Slimline NR1608 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 Slimline NR1608 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 Slimline NR1608 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 Virtual:X: DTS Virtual:X bridges the gap between DTS:X codec and the reality of so many consumers' homes, allowing you to enjoy multi-dimensional sound regardless of room size, layout, or speaker configuration. If you have a limited speaker setup you will miss a full immersive potential of your entertainment system. DTS Virtual:X adds height and surround audio effect to your system without adding height speakers. It works with multiple configurations and delivers immersive sound experience out of 5.1 or even 2.1 speaker layouts.
- 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 Slimline NR1608 comes with Audyssey Dynamic EQ and Dynamic Volume.
- 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.
- MDAX2: Compressed music enhancement in Marantz Slimline NR1608 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 Slimline NR1608 comes with Audyssey MultEQ 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 Slimline NR1608 features 8 HDMI inputs. It has 1 output.
- 4K/60Hz Passthrough: All inputs pass up to 4K 50/60Hz 4:4:4 video signal.
- 4K Upscaling: Marantz Slimline NR1608 can upscale up to 4K 30/25/24p 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 Slimline NR1608 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 Slimline NR1608 is able to pass 3D video through HDMI.
HDR (High Dynamic Range)
Marantz Slimline NR1608 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 Slimline NR1608 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 5 channels will be left for main zone amplification.
- 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
- Analog Pre-Outs: Marantz Slimline NR1608 has 2.2 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.
- Analog Line Inputs: There are 3 line inputs for analog audio connection.
- Digital Inputs and Outputs: 0 optical input, 1 optical output and 1 coaxial input 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: 1
8K Inputs: 0
- Composite Video: Connect you VCR, Laserdisc player and other old video equipment with composite video cables.
- Inputs: 3 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.
- Inputs: 2 Outputs: 1
