Apart from the Marantz NR1509 specs from this Marantz NR1509 review you will know that the compact and powerful 5.2-channel AV receiver provides support for high-definition surround sound with Dolby TrueHD and DTS-HD Master Audio.
The device supports Dolby TrueHD and DTS-HD Master Audio decoders for high-resolution multi-channel audio playback and uses a special mode for energy saving. High-current transistors are involved in five discrete amplifiers of the model, due to which a power of 85 W per channel at 6 Ohms (50 W / 8 Ohms) is achieved and operation is guaranteed even with those speakers whose impedance is 4 Ohms.
The 5.2-channel Marantz NR1509 model is assembled in a low-profile slim package. This form factor goes well with modern flat-panel TVs. For wireless switching, the Marantz NR1509 uses Wi-Fi (two bands), Bluetooth and AirPlay (AirPlay 2 protocol with multi-room audio support for Apple devices will be available after a software update). The receiver can be used as a network player and play files in Hi-Res format (including DSD 5.6 MHz), placed on servers and computers on the local network. The same formats are available when playing through the USB port built into the front of the case.
The presence of six HDMI inputs (one on the front panel) guarantees support for 4K / 60 Hz resolution, HDCP 2.2 protocol, BT.2020 color space and video standards with high dynamic range HDR10, Dolby Vision and HLG. There is an HDMI output with a return channel, coaxial and optical inputs, a 2.2-channel RCA output and an MM phono input. To connect the speakers, screw terminals (five pairs) are used, which are color-coded.
The receiver is “friends” with the HEOS wireless multi-room technology and can be easily integrated into such an ecosystem as a hub. You can control the HEOS system using an application that allows you to send audio files on the local network, as well as audio from tablets / smartphones and streaming content of network services to devices supporting this technology. This ensures accurate synchronization of playing the same track in different locations or sending certain music to the corresponding groups of HEOS devices.
