2. What is RAM®?

Record Active Matching (RAM menu)

It adapts in real time the phono stage parameters to the specificities of your turntable, including: EQ curves, mix mode, cartridge sensitivity and loading parameters. Meaning that, while you listen to the music, you can change the settings until you get the exact sound you can expect. 

In order to activate RAM, go to the configurator, select the remote, and assign one button for RAM

Options on RAM® Menu

 

Once your amplifier switch on, please go into the Phono source, then activate the RAM® menu with the remote button assign to this menu. This changes will be loaded after 2 secs of inactivity. If you are looking to find out all specs and manufacturer recommandations for your cartridge, please consult the manual of your cartridge, or contact the manufacturer. There is another option which is to use an online database where all specs for cartridge are available (such as Vinyle Engine for exemple).

3. Questions & Answers

Can I set my phono parameters via the Configurator?

You can configure your cartridge in the configurator, if you know its type, recommended max level and loading (please refer to the cartridge's manufacturer to collect these informations). On the configurator you will find a list of pre-registered cartridge models, however we do not plan on adding more currently thanks to the RAM feature.

Are Devialet recommend RAM® menu or the Configurator to set the parameters? 

We recommend to use RAM because you can make the changes on fly and adjust the sound delivery while you are listening music.

I did not assign a button for the RAM® menu on my remote 

You can access the RAM menu directly without having a dedicated button. To adjust parameters on the Phono stage please follow steps below:

1. Go into your Phono source
2. Make a short press on the "Tone" button (or the button to acces the "Balance & Tone" options)
3. Browse within this menu, you will find the RAM® Menu (To browse, you will just have to make short press with the tone button to pass from a page to another in this menu).
4. Use the wheel to change parameters in the RAM® Menu.

Where can I find all specs for my cartridge?

These information are in the instruction manual of your cartridge, if you did not kept it you can still contact the manufacturer or the seller of your cartridge. Additionally there are existing database with all specs for cartridge available online such as Vinyle Engine

Recommendations made by the manufacturer can still be adjust "on fly" via the RAM® menu. Once you set it up, all parameters will be locked into your amplifier and will be apply everytime you are switching on this source.

Even after fine tuning my parameters, the cartridge sound is not as expected

First, check that the cartridge is in a good condition.

Then check that it is correctly wired to the arm of the turntable.

Lastly, also check if you need to wire the earth ground or not. A turntable is "over-amplified" to ensure a good condition for listening vinyle, therefore every surronding voltage could be'hearable' and have a bad effect during your listening session.

A good test to try is also wire another turntable to the amp, and see if only one of them produces a bad sound.

I hear a noise on the Phono input - like a "gun noise"

As a reminder the phono input is very sensitive to all environnement's noise, as a safety check please ensure that the cabling beetween both Expert and Turntable are properly set.

In your configuration ensure that the Wifi is disable everytime you are using your Phono input within the setting of your Input

 

Lastly, also check if you need to wire the earth ground or not. A turntable is "over-amplified" to ensure a good condition for listening vinyle, therefore every surronding voltage could be'hearable' and have a bad effect during your listening session.
