1. The Phono inputs on Expert

Devialet 120/130 Pro / 140 Pro

Both the Devialet Expert 120 and the Expert 130 Pro come equipped with an identical number of inputs. They each feature a Line input that can be converted into a Phono input using the Configurator.

1.b Devialet 200 / 220 Pro/250 / 250 Pro - 210 Pro / 400 / 800 / 440 Pro / 1000 Pro

These Devialet amplifiers come with various input options. Each of them includes a dedicated phono input (Phono 2) that can be transformed into a Line input. Additionally, there's a dedicated line input (Line 1) that can be converted into either a Phono input or two mono digital (SPDIF) inputs.

2. What is RAM®?

Record Active Matching (RAM menu)

It dynamically adjusts the phono stage parameters to match the characteristics of your turntable, which encompass EQ curves, mix mode, cartridge sensitivity, and loading parameters in real-time.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 a button for RAM.

Options on RAM® Menu

 

Once your amplifier is switched on, go into the Phono source, then activate the RAM® menu with the remote button assigned to this menu.

These changes will be loaded after 2 seconds of inactivity.

If you're seeking to gather comprehensive specifications and manufacturer recommendations for your cartridge, we recommend referring to the cartridge's manual or reaching out to the manufacturer directly for assistance.There is another option which is to use an online database where all specifications for cartridges are available (such as VINYL ENGINE).

To adjust the value for each option, simply turn the wheel on your remote and press the tone button to move on to the next available option.

Channels:

  • Stereo (by default)
  • Mono
  • Left or Right

EQ Curve: 

RIAA1953

RIAA 1976

  • 0.10mV to 1.00mV (in 0.01mV steps), for MC
  • 1.00mV to 15.00mV (in 0.1mV steps), for MM
    (NB: 0.1mV = 100uV).

Note:

  • MC stands for Moving Coil
  • MM stands for Moving Magnet

3. Questions & Answers

Can I set my phono parameters via the Configurator?

You have the option to configure your cartridge using the configurator if you have information about its type, recommended maximum level, and loading specifications (please consult the cartridge's manufacturer for this data). The Configurator includes a list of pre-registered cartridge models, but currently, we do not have plans to add more due to the RAM feature.

DOES DEVIALET RECOMMEND THE RAM® MENU OR THE CONFIGURATOR TO SET PARAMETERS?

We recommend using RAM because you can make changes on the fly and make adjustments while you are listening to music.

I DID NOT ASSIGN A BUTTON FOR THE RAM® MENU ON MY REMOTE, HOW CAN I ACCESS IT?

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

  1. Go into your Phono source
  2. Press the "Tone" button (or the button to access the "Balance & Tone" options)
  3. Within this menu, you will find the RAM® Menu (To browse, you can press the tone button to move from one page to another in this menu).
  4. Use the wheel to change parameters in the RAM® Menu.

WHERE CAN I FIND ALL SPECIFICATIONS  FOR MY CARTRIDGE?

You can find this information in the instruction manual for your cartridge. If you no longer have the manual, you can still contact the manufacturer or the seller of your cartridge to obtain these details. Additionally, there are existing databases with all specifications for cartridges available online such as what can be found at VINYL ENGINE.

Recommendations made by the manufacturer can still be adjusted "on the fly" via the RAM® menu. Once you set it up, all parameters will be locked into your amplifier and will be applied anytime you switch to 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 whether you need to connect the grounding or not. Turntables are often "over-amplified" to ensure optimal vinyl playback conditions, which means that any surrounding voltage could potentially be audible and negatively impact your listening experience during a session.

Another useful test to consider is connecting another turntable to the amplifier and determining whether only one of them produces undesirable sound quality. This can help isolate the source of any potential issues.

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

As a reminder, the phono input is highly sensitive to environmental noise. To ensure a trouble-free experience, please double-check that the cabling between both the Expert and the turntable is correctly configured and secured.

As part of your configuration, make sure to disable Wi-Fi anytime you use the Phono input. You can find this setting within the input options.

 

 

Finally, also verify whether you need to connect the earth ground or not. Turntables are typically "over-amplified" to ensure optimal vinyl listening conditions, which means that any surrounding voltage could become audible and potentially have a negative impact on your listening session.
