At certain points in troubleshooting an issue with our Concert AV receivers, or our Maestro pre-processor it is a good idea to reset the system to factory default.

In order to do this, you will first have to access the Engineering menu.  Press and HOLD the Menu button on the front panel for at least 3 seconds.

The front display will read “setup menu” but you should see this menu pop up on your TV screen:

eng_menu_home

When you reset to factory defaults, this will wipe out all settings that are on the unit.  In order to not lose any of these settings, you will want to “Store secure backup” first.

eng_menu_enterPIN

The menu will ask for a PIN.  The default PIN is 0000.  It should be pre-loaded.  You will just need to press the select button to confirm the PIN.

eng_menu_enterPIN_2

After it stores the backup, you will then want to “Restore to factory defaults”.  When you choose this option, it will give you this message:

eng_menu_reset

Press Direct to confirm, and this will turn off the AVR/M9.  You will just need to turn the unit back on and go back into the Engineering menu by pressing and holding the Menu on the front panel again. At this point, you will just need to select “Restore Secure Backup”. The unit will turn off again, you will then turn the unit back on and you should be good to go!
