A passive bass trap absorbs low-frequency energy using physical materials such as mineral wool, fiberglass, foam, or membrane absorbers. An AVAA (Active Velocity Acoustic Absorber) uses a microphone, electronics, and a loudspeaker to actively absorb bass energy. Instead of relying on large amounts of material, it creates a low-acoustic-impedance boundary that "pulls" low-frequency energy out of [...]
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.
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 [...]
Yes PSI Audio products will work in all countries. 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 [...]
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 [...]
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 [...]
