Welcome to our FAQ (Frequently Asked Questions)

We recommend a minimum of 2 units to keep symmetry in a room.

The number of units is dependent on the number of locations that need to be treated more than the size of the room.

In practice, the first two units are placed where they are most useful to the listening position, so they will have the greatest impact. Adding other units in different places further reduces the room modes.

The AVAA C214 and AVAA C20 are very comparable in terms of performance.
The main difference lies in the design and size, which make the AVAA C214 easier to integrate into a room.
What’s more, the AVAA C214 can be individually controlled via a smartphone app to turn it on and off and to adjust the gain.
Gain can be reduced on both models if the device shows signs of instability in its environment (where it is positioned).
On the AVAA C214, it is also possible to increase the gain and make it more efficient.

The AVAAs are pressure-based absorbers and will therefore be most effective in location where the pressure build-up is greatest. As it is almost impossible to model the acoustic behaviour in a room, the following rules offer a rapid way of find the best positions:

• In the corners.
  Corners will generally be most the most effective location as they combine pressure build-up from with lengthwise, width wise and vertical room modes.
• Against the most rigid wall.
  By definition, flexible walls will move and let sound through. Rigid walls will move less and have greater pressure build-up.
• Closest to the source of sound.
  If all corners are identical, we have generally observed greater efficiency in corners closest to the source of sound, such as behind the loudspeakers.

And of course, the best result in the listening position is easily achieved after a couple of trials with AVAAs in different positions.

Refer to the user manual for further details.

When the AVAAs are positioned in a high pressure area of a room mode, the room mode resonance time (RT60) is typically reduced by 30% to 50%.

The result is less low frequency ringing, clearer mids and highs with reduced masking effect and better imaging.

It is important however that the voltage is set to match the voltage of the mains (i.e.  230 V or 115 V). This is normally done by the importer who will make sure the products are set up for the local network.

The procedure is explained in our manual:
“Check that the voltage value on the AC power selector is set correctly (according to your local AC power supply). If this is not the case, it will be necessary to adjust the main power supply with the following procedure. Carefully squeeze the two latches on either side of the fuse plug and pull the fuse holder out of its socket. Now replace the fuse for the different voltage setting with the correct value fuse according to the required voltage. The correct value of the fuse is printed next to the OnOff switch of your loudspeaker. Pull out the grey plastic cap which holds the fuse and turn it 180° so it shows the correct voltage setting through the outer window when placed back in its position. Now you can carefully push the complete fuse holder back into its place above the mains connector”
