Expert Pro is the last range on Expert, composed by our Version 6 of the Expert Hardware component. Expert Pro is also onboarding a brand new board - the Core Infinity.

4. Where to start

A - Plug all your material

First step you need to do, is to wire your system with all material you need to connect (CD Player, TV, Turntable, etc...)

B - Update your firmware

Once you made it, to ensure your device is up to date, we recommend you to make the firmware update of your device(s).

  • Log into your Web account here
  • Go into the page "Expert Configuration" on the first section of this page you will be able to download the apropriate firmware 
    1. For Expert Pro last firmware available is the 13.0.0
    2. For Expert (non-pro) last firmware available is the 10.1.0
    3. If you like to check the current version on your device, you can use the tone button of your remote with long press to access the Advanced menu - the software version is just aside the SW (which stands for Software Version) mention in the Expert screen.
  • Download the right version of firmware
  • Insert your SD Card into your computer and format it properly (if you do not have a SD Card reader, please consult external reader product available here)
  • Put all firmware files into the root of your SD Card
  • Unplug the electrical cable
  • Insert it into your Expert and
  • Replug the electrical cable.
  • Firmware update will start from there

Note: if with the above steps you can not update your firmware for any reasons, please consult the following article Firmware Update Q&A 

C - Customize your configuration file

One important aspect of your Expert system, is that you can fully configurate it such as naming source, pre-load your speaker profil, etc...For a basic configuration, please have a look at the following article Simple Configuration

For a more complete configuration, look at all options available into the Configurateur here. When the configuration is complete, download it and paste it into your SD Card. the configuration file should be named dp_cfg.txt if this is not the case your Expert won't be able to read it (on the screen will dispaly "factory config" when booting. 

D - Just now enjoy the music!

5. Q&A

My companion or my master is very hot - is this normal?

The heat dissipation is solely done by convection (there is no ventilation in the Devialet), we advise not to have the unit in a cabinet or in a place with poor air circulation.

You can check the Devialet’s temperature by pressing 2s on the remote tone button and going to screen 14th ont the Devialet’s information screen. You can navigate the screens by shortly pressing on the tone button. Temperatures going up to 65°C are absolutely OK.

Additionally for DUAL-Mono setup, we highly recommend you to set device side by side rather than one on top of the other one.

My remote is not longer paired to my Expert Pro - how can I pair my Remote?

If you need to pair your remote on your amplifier, here are the steps to follow:

  1. Switch on your amplifier
  2. Put the Remote on the casing on the Devialet writing on the top of the casing
  3. Turn the wheel of the remote till you see the volume on the Expert screen changing the volume.

Theses steps are the same for pairing a Remote to a Dpremier, and Expert or an Expert Pro

How to clean my Expert?

Both the amplifier's body and the remote control is made of hand-polished solid aluminium with a layer of copper and nickel. The delicate surface is sensitive to finger acidity and grease. We recommend that you regularly clean the surface with the supplied cloth. If marks or stains are persistent, you may want to use a soft cloth moistened with alcohol or a window cleaning product.

What is the factory mode on Expert and how to activate it?

 

The factory mode is the mode where no set of parameters are activated. It's exactly the same mode as when the product leaves the factory.

We usually use this mode to identify trouble on Expert, and see if a particular parameter is generating the issue you may face.

 

For example:

If the Expert is generating the same issue with parameter load (with a configuration) as without (factory mode), it means potentially either: 

  • Device plug in the Expert is generating the issue (CD player, Speaker, etc...)
  • A part of your expert is not working properly.

On the other hand, if the factory is not generating the issue as when parameter is load, it means that there is a feature which is not properly configurated on your configuration file (eg. SAM), therefore the next step our team may ask you will be about redo the configuration of your Expert via the Configurator

 

To return your Expert on factory mode, please follow the below instructions:

  1. Switch off your Expert.
  2. Remove SD card of your Expert (on both units if this is a Dual mono device)
  3. Switch on your Expert 
  4. You are then on factory mode. 

 

To leave the factory mode, please follow the below instructions:

  1. Switch off your Expert.
  2. Put on the SD card reader SD card of your Expert (on both units if this is a Dual mono device)
  3. Switch on your Expert 
  4. You are then on a configurated mode. 

 

This might be a test to run before reaching out our customer service team in order to get some more insight on where the issue might be located.

Can I adjust the balance and tone on my Expert? How can I make this adjustement?

Devialet amplifiers offers Tone and Balance adjustment possibilities.

To access and exit these controls

  • do a long press (2s) on the "Bass" on a D-Premier or the Mute key on a Devialet 250, 250 Pro, 200, 220 Pro, 120 or 140 Pro.
  • Navigate through this menu with short presses.

 

The tone control is unique in the sense that you can define the exact bass or treble frequencies where you want the correction to operate. This can be defined in the "control settings" section on the online configuration tool. Note that by default, the frequencies are set to 100Hz and 2kHz.

The balance control lets you correct problems due to unusual geometry of the listening room. By default, the unit will automatically switch to mono as soon as you attempt to adjust the balance on the remote control. This is helpful in case the musical content is different on the left and right channels when adjusting the balance. You can also configure your unit to stay in Stereo during balance adjustments. This has to be defined in the "control settings" section on the online configuration tool.

Note that both balance and tone adjustments are automatically memorized as soon as you leave the menu item.

  2. First information that appears in this screen are the main information (serial number/Hardware version/Software version etc...)
  3. To move into this menu, you will need to make a short press on the tone button again, until your screen view a "Last fault" menu.

This information will disappear if you are doing a reboot of your amplifier (by unplugging and replugging the product).

An advanced information-menu is available to service your Devialet. It contains detailed data about your product:

  • Screens 1-5: Serial numbers, firmware, software and hardware versions
  • Screens 6-7: Wi-Fi status and related information
  • Screens 8-10: Device configuration
  • Screen 11: Temperatures in the set
  • Screen 12: Last fault found

The Last Fault found screen is important to report, should your device stop during operation (i.e. enters protection mode) or show unusual behaviour. Note that this information is stored for 3 days in memory, unless Devialet is reset by disconnecting it from the mains.

To access and exit this menu, make a long press (>2s) on the Phase Invert (D-Premier, Devialet 250) or the Tone key (Devialet 200, 120) of the remote control. You can navigate through the various screens by doing a short press on the same key. You can also exit this menu by making a short press on the remote control’s On/Off button.
