What is a preout ?

Devialet amplifiers are mainly equipped with inputs, which means that you can connect third-party devices, such as a CD player for example, and thus amplify the received signal and play it on the speakers.

 

There are instances where it may be necessary to route the audio signal from the amplifier, such as when you want to listen to music using headphones, for example. We call it pre-amplified output or PreOut and this is configurable via the Devialet configurator.

Questions & Answers

  • Is it possible to connect a stereo "Subwoofer"?

Of course it's possible, you can follow above instructions, but the output to be set will be "Pre Amplified (Stereo)"

  • Can I filter the subwoofer's signalLe signal vers un subwoofer peut etre filtré ?

There are some setting to be use on the configurator

  1. Full range - it means that the whole frequences will be played by the subwoofer

  2. High pass - the signal will remove the bass frequences selected (based on the settings). This setting can be used for the small speakers which are not able to play very low frequences.
  3. Low pass - The signal will removed the low frequencies (based on the settings)
  • After connecting the headphones via a wired connection, you may encounter a situation where there is no sound coming through them.

Make sure that the remote is properly set with an assigned button ("Pre amplified Output"), and switch on/off the button 

  • Can I use SAM on my headset? 

SAM is primarily designed for use with regular passive speakers and may not be compatible with headphones or headsets. The technology is optimized for enhancing the performance of passive speakers, and it may not function when connected to headphones due to differences in audio delivery and processing
