Selected Features

Amplifier

Marantz Slimline NR1508 has 5 channel amplifier and delivers 50 W (8 Ω, 20 Hz - 20 kHz, 2 channel driven) and also has a stable performance at 4 Ω load.


Video Features

The Receiver has 4K passthrough up to 60p.


MDAX2

Compressed music enhancement in Marantz Slimline NR1508 is done by Marantz’ MDAX2 technology. The use of compressed audio files like MP3, Windows Mediaβ„’ 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.


Audyssey

Marantz Slimline NR1508 comes with Audyssey Dynamic EQ and Audyssey Dynamic Volume.

Audyssey 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.

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.


Room Correction

Marantz Slimline NR1508 comes with[y] Audyssey MultEQ room correction system and includes the calibration microphone.

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.


Connectivity

Marantz Slimline NR1508 can be connected to internet using ethernet cable or built-in wi-fi adapter. It can also connect to bluetooth devices via built-in bluetooth adapter. The Receiver works with Amazon Alexa and supports[y] AirPlay 2. It has 6 HDMI inputs and HDCP 2.2 copy protection. There are 2.2 channel analog pre-outs for external amplification.

Front panel has HDMI and USB inputs.
