Software installation for Anthem AVM 60, MRX 1120, MRX 720, MRX 520

The same firmware file applies to all the above models.  Model version is automatically detected.

1.  Copy the extracted "MRXx20_USB.fw" file to a USB memory stick, root directory.  Make sure there are no other .fw files in the root directory. 

2.  Connect the USB stick to AVM/MRX front panel, behind the cover in the lower left.

3.  Go to the setup menu / System Info / Update Via USB and follow the instructions.

Alternative method if a monitor is not available:

With the unit turned on, press the Select button on the front panel for 3 seconds to start the process, then let go. The front panel will indicate that the unit is being updated.  Installation can also be initiated from the setup menu.  The unit will turn on and off a few times over the next few minutes.  When installation is complete, the normal input/volume display is shown.

Very important:  Do not interfere with the unit by pressing buttons or turning power off while software is being installed.

If software installation does not start or the AC cord needs to be disconnected/reconnected to make the unit operable again, try a different brand USB stick, preferably one without unneeded software that is sometimes supplied with new USB sticks.

V02067_2016_12_14.fw:


1.  (AVM 60 and MRX 1120/720) Added dtsX decoding and Neural:X upmixing, including compatibility with Dolby Enabled upfiring speakers.

Info:

DTS:X dialog level control - this applies only to dtsX sources making use of the function.  To raise or lower the level of the dialog (actor voices), use the PG/PR up/down buttons on the remote. The range is 0-6 dB, default 3 dB.

DTS Neural:X uses all speakers in a DTS:X system for an immersive audio experience, creating separation by placing sounds at different points in the sound field. This mode does not apply to DTS:X Master Audio, DTS:X, Dolby Atmos, Dolby TrueHD, and Dolby Digital Plus sources

DTS Neural:X setup (input setup menu) - When the source is a DTS stream, Direct mode plays the audio channels as they were recorded, whereas Non-Direct mode (default) adapts the audio to your speaker layout if it is different from the content creator’s.
