7 channel Amplifier

Marantz Slimline NR1605 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.

    Speaker Configurations

    Marantz Slimline NR1605's 7 channel amplifier can be assigned for different speaker configurations.

    • Configurations: Available configurations are:
    • 5.1, 7.1 with internal amplifier.
    • Bi-Amp: You can bi-amp front left and right speakers. 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.

    Sound Processing

    • Audyssey: Marantz Slimline NR1605 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 NR1605 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.

    Room Calibration

    Marantz Slimline NR1605 comes with Audyssey MultEQ room correction system and includes the calibration microphone.

    • 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.

    Video Section

    HDMI

    Marantz Slimline NR1605 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 NR1605 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 NR1605 will output them via HDMI. This means that you will need only one HDMI cable to connect to your TV.
    • 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 NR1605 is able to pass 3D video through HDMI.

    Multi-zone Playback

    Marantz Slimline NR1605 offers multi-zone playback which allows you to play different input sources in 2 different rooms.


    Zone 2

    • 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

    Audio

    • Analog Pre-Outs: Marantz Slimline NR1605 has 2.1 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: 1 optical input 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.

    Video

    • HDMI:
    • 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.
