The vibroacoustic amplifier transforms any furniture into a vibroacoustic element, providing stimuli that allow users to feel the music and sounds like a vibrant and relaxing experience all over the body.

Includes a pre-amplifier stage to which you can connect any music player.


  1. Low frequency amplifier

2. Pre-amplifier stage

3. RCA – RCA cable 

4. Jack 3.5 – Jack 3.5 cable

5. Pre-amplifier power suply

  • Two 230V power socket must be available for the amplifier and the pre-amplifier stage.

Connect the different elements following the next diagram:

  • Connect the sound source (MP3 player, PC, etc.) to the pre-amplifier using the jack-jack cable provided (4).
  • To connect the cable, insert it in the jack input and turn the grey disk on the jack slightly to ensure a good connection.
  • Check by pulling lightly on the jack to ensure that it is correctly secured.
  • Connect one end of the RCA-RCA cable (3) to the corresponding amplifier input, and the other end to the pre-amplifier stage, as shown in the following pictures.

  • Connect the power supply cable to the amplifier.
  • Connect the power supply to the pre-amplifier stage.


  • Connect the amplifier to the power supply.
  • Connect the preamplifier to the power supply.
  • Turn ON the amplifier.
  • Turn ON the sound source (mp3 or other). Adjust the volume to an appropriate level.

Vibration regulation

The amplifier allows the vibration intensity to be adjusted. The vibration level should be adjusted via the controls on the front, particularly via the CH.A control (or CH.B if there is a second vibroacoustic element).


  • Keep the CH.B control on minimum when only one vibroacoustic element is used.
  • When the vibration level is adjusted, if the “CLIP” indicator is permanently ON (red LED) lower the setting immediately until the indicator turns off
  • Not following these indications can lead to the malfunction of the vibroacoustic amplifier.
  • Before cleaning, disconnect the equipment from the wall plug.
  • Clean using soapy water and a soft cloth (wrung out).
  • Never use chemical or abrasive products for cleaning.
  • Carefully dry the product and do not power it until it’s completely dry.
  • Make sure the ventilation openings are free of dust to ensure proper ventilation of the device.
  • It is recommended a periodic inspection of the devices, in case of detecting any anomaly disconnect the device from the current and immediately contact your supplier for assistance.

In case the shakers do not reproduce any sound, check the following points:

Should any sound come through the vibration device?

This element is designed to produce a vibration from an audio signal, not for audio reproduction. Even so, you may notice a slight sound through the vibration device.

How could speakers be connected to listen to the music?

To connect some speakers you need an audio splitter cable connector.:

For this the main cable should be connected to the sound player and in each of the 2 outputs must be connected the vibo-acoustic amplifier and to the sound system of the speakers.
