Home/AV-receiver /Arcam FMJ AVR550

Overview and description of the AV-receiver Arcam FMJ AVR550

The 7.1-channel Arcam FMJ AVR550 from the upgraded proprietary line of AV receivers supports the Dolby Atmos format in a 5.1.2-channel configuration. For expansion to configuration 7.1.4, it is recommended to supplement the system with a 4-channel tip or a pair of 2-channel assistants. The model works with all major codecs, incl. with DTS-HD Master Audio and Dolby TrueHD, and after the release of the new firmware will be full support for DTS: X.
Among the design features include the return of the traditional knob to adjust the volume, which was absent in the AV devices of the previous line. The regulator is installed in the center of the slightly curved front panel. Above is a 2-line display, and to the left and to the right are five buttons with which you can select a source, enter the menu, turn on Direct mode to get high-quality stereo sound and activate other functions. On the right side of the facade there is a power button and a standby mode indicator, as well as a 3.5 mm headphone jack and a 3.5 mm line Aux input.
The model is equipped with a powerful toroidal transformer and is capable of producing 7 x 90 W at 8 Ohms. On board there is an FM tuner. Digital radio DAB is supported (not available in Russia). The Arcam FMJ AVR550 can be integrated into a local network via an Ethernet port, as well as playback of compressed files and lossless formats that are stored on devices of this network (UPnP servers/PC/Mac). It supports vTuner (web radio) and the Spotify web service. Control of the device is available using the remote control, via the network (IP control) or through the MusicLife app for iOS devices.
The Dirac Live progressive system is used to auto-calibrate the speakers, which uses a microphone connected to a computer with Direct Live software installed. In this case, the computer must be connected to the same local network as the AV receiver.
The device received 7 inputs and 3 HDMI 2.0a outputs with support for HDCP 2.2 technology, which allows you to play copy-protected content in Ultra HD resolution. One of the HDMI ports supports MHL function for playing HD video from mobile devices. There is a wide selection of digital and analog inputs, as well as 7.2.4-channel Pre Out (RCA). The rear panel is equipped with a USB port for external drives, trigger connectors, RS-232 interface and other connectors. To connect the speakers involved 7 pairs of screw terminals, two of which can be used for zone 2.
The receiver Arcam FMJ AVR550 belongs to the audiophile class of components and is able to provide excellent sound quality, both in DC and in a two-channel system.
