A23-M – New!
The A23-M is PSI Audio’s new member. It is a compact 3-way mid-field monitor with staggering precision and amazing stereo image. The dynamic behavior, precision frequency and phase responses have made of the A23-M a true reference in the entire industry. The handmade tweeter used on the A23-M has already made the success of our biggest 3-way studio monitor, the A25-M. To achieve the ultimate precision for this compact 3-way, it was also necessary to build our own midrange woofer. After more than 2 years of analysis and development, we were proud to release the current version, which is the most accurate mid that you can find on the market. Tri-powered with our own analog amps (Class G/H for bass + midrange woofers and Class A/B for the tweeter), the A23-M is the top of the art compact 3-way dedicated to music recording, mixing and mastering, broadcast and post production. When used with one of our subwoofers, the A23-M will transform in an amazing 4-way system, with ultra precise control on all the frequencies, from very low until the highest notes. |

A214-M
PSI Audio A214-M is mainly designed as a “centre” speaker for surround monitoring applications. However, the unit may also be used as a basic component for all monitoring requirements. The A214-M employs two woofers of 147mm and one tweeter of 100mm, for a programme power-handling of 160W. The speaker has sufficient acoustical output to satisfy the requirements of post-production and film mixing suites, as well as for other mixing applications. PSI active loudspeakers feature CPR (Compensated Phase Response) and AOI (Adaptive Output Impedance) technology that is a hallmark of the company. A major advantage is that it allows monitor systems to be made up from different models, without any detriment to the overall phase response of the system. The shallow height of the A214-M (less than 200mm) allows the speaker to be easily incorporated into surround installations where space is an important factor |

A225-M
An exceptional piece of acoustic design, the A225-M sub-woofer/bass extension is equally suited to use as a mono sub-woofer in a surround sound application or as a bass extension in a stereo system. Designed to work in harmony with the A225-M Sub, all PSI Audio ‘A’ series speakers feature a frequency response roll-off function that, when combined with the A225-M Sub, extends the frequency range down to an incredible 24 Hz, whilst maintaining a flat response. The powerful class G outputs feature PSI Audio‘s unique “AOI” output stages, giving the A225-M an unprecedented impulse behavior. Each driver and amplifier unit is secured by a protection circuit, which is monitored by a red LED on the front panel. The electronics are housed in a unit mechanically isolated from the speaker cabinet to avoid resonance at high sound pressure levels. To provide stability and avoid cabinet resonance A225-M is built with a double-box design, combining two cabinets into a single beautifully finished unit. |

A125-M
PSI Audio now extend their range of products with a small-sized subwoofer, the A125-M, that is designed to extend the bandwidth of their monitors down to 28 Hz. All of PSI Audio monitors have a roll-off that reduces low frequencies by up to 10 dB. Their subwoofers are designed to seamlessly extend the frequency of any PSI Audio monitor. This means that the monitors, with roll- off, and subwoofers are perfectly in phase and that the total frequency response is flat.The SPL of the A125-M is adapted to work with PSI Audio’s smaller monitors such as A14-M, A17-M (see photo) or even the A21-M. Two of them will also work in stereo with the larger models such as A21-M and A25-M. The dimensions are 32 x 38 x 48 cm and it weighs 21 kg. It is equipped with a single 25 cm driver in a double wooden cabinet driven by PSI Audio’s class-G amplifier and analogue technology. |

AVAA – Active Velocity Acoustic Absorber
The AVAA is a solution for room mode problems. The AVAA is designed to absorb the standing modes between 15 and 150 Hz in a room. It will do so just like passive absorbers but in a much more efficient way and using up much less space. Each operating AVAA will have the same effect as a hole in the wall much larger than the dimensions of the AVAA (that is 0.2 m2). The exact ratio will depend on the frequency and environment but typically range between 5 and 20. The AVAA will affect the impedance of the air and “suck” low frequencies around it. Therefore the best position to place an AVAA is in the most rigid corners as that is where all room modes will be most present. It is important to work on the positioning of loudspeakers and listening, as the AVAA will have little effect on inevitable first reflections. |

About PSI Audio
The story of PSI Audio started in 1975 when Alain Roux started producing his first speakers while studying at EPFL in Lausanne. Two years later Alain started making a profit selling his speakers and decided to found a company called Roux Electroacoustique. In 1988 the company became a Limited Company and was renamed Relec SA. At this time Alain also relocated the company in to a new purpose built facility in Yverdon-les-Bains.
Over the years, Alain and his team developed a huge variety of speakers starting from the Hi-Fi industry, Public Address systems all the way to Professional Studio applications. Many speakers where also produced as OEM products under the brand names of respected international companies. Several of these products have gone on to win the industry’s most desirable awards.
In 1991 an analogue and digital electronics section was added to the acoustic laboratory and electronics expert Christian Martin was recruited, to lead development in these areas. From 1992 until 2003, Relec SA had the privilege to work in close partnership with the Studer. Relec SA developed and produced the OEM line of monitors for Studer comprised of A1, A3 and A5 all of which are recognised worldwide. In 2004, Studer was acquired by an international group and had to stop selling studio monitors under the Studer brand. Relec SA and Studer therefore had to discontinue their fruitful relationship. This was then the start of PSI Audio brand in the studio monitoring…
Since then, PSI Audio has developed to become a respected worldwide brand, producing the ultimate professional studio monitors. PSI Audio now offers a full range of highly innovative speakers with cutting edge fully analogue technology.
