PSI Audio has announced ‘the next evolutionary step’ in its acoustic absorption technology, the AVAA C214.
With the development of AVAA, PSI Audio developed a means to manipulate the acoustic impedance in front of the device. The result is the elimination of resonant frequencies from the room – not just for the sweet spot, but the entire room. AVAA covers the spectrum from 15Hz to 160Hz and does not require calibration or tuning. Any room modes in this range will be eliminated, clearing the listening space from unnecessary rumble in the very spectrum that is so hard to treat with passive acoustics. Reckoned to be 45 times as efficient as classic absorbers of the same size, AVAA saves space while yielding impressive results. Since it deals with room modes, it particularly improves the room’s response over time: a short bass pulse does not keep ringing.
The new C214 takes the AVAA technology and approaches it slightly differently. While the original C20 is completely analogue (and will remain available), the C214 employs digital technology. As a result, the new model can react more flexibly to the room, and can be controlled with a smartphone or tablet. The corresponding app is available for iOS and Android and allows remote controlling the AVAA C214 individually or in a group. It can switch one or multiple devices on or off, and allows for a wider sensitivity adjustment for tweaking the system’s efficiency and achieve optimal absorption.
A new control system ensures optimal performance even when sudden changes in the room’s impedance occur. The C214 replaces the large membrane in the C20 with two smaller ones, hence reducing its footprint and allowing for an even more compact and stylish design that can be mounted to any location in a room –the floor, the wall and the ceiling.
The AVAA functionality does not change with the new C214 – the new model eliminates room modes just as efficiently, if not even more so, than its all-analogue predecessor. AVAA acts like a hole in the wall, letting sound waves ‘pass through and leave the room’. With its compact and neat design and its extremely high efficiency, AVAA is a particularly mobile solution: if the listening environment needs to move, AVAA devices will just move with it and take up their function again in the new space. Though AVAA is an active bass trap it still behaves like a typical bass trap: There is neither anti-sound emission nor noise cancelling nor a ‘reversed’ subwoofer – just highly efficient absorption. AVAA is arguably the easiest, most elegant and most flexible acoustics solution for room modes possible.
Manufactured to the same high standards as the active speakers from PSI Audio, the AVAA C214 ‘is a precision instrument that delivers absolute performance and unveils the music as it should be’.
