We are more sensitive to directivity on the horizontal plane that on the vertical plane. Also dispersion is wider left-right of the monitor than top-bottom. Therefore in theory it is best to have the drivers of a loudspeaker in vertical position as the sweet spot will be larger. In practice many users position their monitors [...]
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 [...]
The components we use don’t vary over time and the settling time is of a few seconds only. So in normal use conditions the burn-in is not necessary.
Our monitors are all calibrated to be as accurate as possible. In 2015 we upgraded the woofer baskets on the A21-M and A17-M to a cast aluminum basket for solidity reason. The basket is stringer but there is no difference to the driver itself nor to the sound.
First of all our approach is scientific and defines the role of a loudspeaker as being to transform and electric signal into an acoustic signal as accurately as possible. The loudspeaker manufacture should not make the sound and should respect the artist and sound engineer’s or designer’s work. A loudspeaker should be able to reproduce [...]
First of all the response from the different drivers and the port should combine perfectly to provide a flat frequency and linear phase response. The cross-over between the port and the woofer needs to be carefully adjusted and this lacks in many bass-reflex loudspeakers. Then our AOI system ensures that the woofer membrane accelerates fast [...]
The most important part of a cable is the contacts and it is important to choose cables with good quality connectors and good shielding for the XLR cables. There are many good cables on the market and we can only recommend any particular type or brand.
The latency in PSI Audio speakers depends on the model but is below 0.6 milliseconds. This is the time between when the electric signal enters the monitor until the acoustic signal comes out. It is very important to have very low latency for all live recording, mixing and post-production.
In an passive speaker the amplifier is outside the loudspeaker cabinet and can be at quite a distance. With PSI Aduio active speakers you have many advantages: Each driver has its own amplifier, designed and built A 3 way system has 3 amplifiers each perfectly adapted to each driver The amplifier is as close as [...]
Most of what can be done with digital technology can also be done with analogue technology. The advantage of analog technology is that it is faster and often avoids unnecessary conversion to and from digital. Our monitors are phase linear. This is achieved through a series of carefully adjusted all-pass filters with a maximum latency [...]
