Descrizione

The DPA-1 is a true digital pre-amplifier from Lyngdorf incorporating the innovative RoomPerfect room correction technology that allows you to access to the real sound of your audio system.

The DPA-1 digital pre-amplifier is much more than a pre-amplifier with room correction: It is also a complete digital signal processing control center for designing advanced loudspeaker set-ups.

To ensure maximum compatibility and easy connection the DPA-1 offers both single ended and balanced inputs/outputs. So, connect a source, analog or digital, and hook it up to your and power amplifier(s) - and you are done!

The RoomPerfect room correction technology in the DPA-1 pre-amplifier effectively removes the room from the "good sound" equation. The technology used to do this simply represents state-of-the-art within room correction. And test results from all over the world confirm that it also works perfectly in "real life".

It works and makes a world of difference - but how is it to operate? Well, even though this is the most sophisticated room correction system in the market it is very simple to use. You don't need to know anything about acoustics or computers to get full benefit from RoomPerfect. The menu will guide you through the calibration and everything needed; microphone, stand and cable come included with the DPA-1. So, you are easily up and running in less than 1- hour!

Try out the Lyngdorf DPA-1 - that is, of course, if you want to discover the real sound of your audio system.

When listening to your audio system you hear the 3 dimensional soundfield - i.e. the direct sound from your speakers as well as all the reflections. The reflections add ambience and thus the sensation of "space" and "air". However, most room corrections systems measure only at the listening position meaning that the correction is based on one-dimensional information.

At Lyngdorf, we solved the problem with getting 3-dimensional room knowledge in a very unique way.

The RoomPerfectTM system is capable of combining the information about the listening position with the information about the energy transport into the sound-field in a wholly new and innovative way.
The measurement at the listening position holds information about your access to the sound-field while the room positions hold information about the 3-dimensional sound-field in the entire listening room.

Thus we can ensure that you achieve perfect sound, irrespective of your listening room, speaker position and listening position. In fact, the vast amount of information gathered about the sound-field allows you to enjoy the benefits of room correction in any position throughout the room.

Amongst other things RoomPerfect can - as the only system in the market - derive information about:
- Room Acoustic properties, modes (peaks and dips in the room)
- Power response throughout the room
- Loudspeaker directivity
- High frequency roll-off
- Characteristics of low frequency roll-off

From the acquired measurements RoomPerfect processes the information and sets up amplitude targets and limiters for the different filters in an all automated process.

RoomPerfect automatically identifies the optimal target curve for your speakers from the information in the measurements and everything is thereafter controlled by the guided setup in the menu system.
A complete calibration typically comprises of 4-6 measurement and can be done in less than 15 minutes!

Also, RoomPerfect allows you to break away from conventional "free space" placement of your speakers.
Normally, you need to place a loudspeaker well away from rear and side walls to secure the flattest possible frequency response. Due to the fact that a traditional box loudspeaker has omni polar dispersion in the bass region, this "free space" placement has a big disadvantage namely that you actually risk "destroying" the impulse response. The reason for this is that you hear both the direct sound from the speaker and later all the reflections from the walls. The reflections are delayed as a consequence of the distance to the walls and will therefore arrive later thus smearing the "attack" of e.g. a drum beat.
If you place the loudspeaker close to the back wall the bass reflections from the wall and the direct sound will arrive simultaneously at the listening position - i.e. the impulse response in the bass region can be improved considerably and RoomPerfect can easily compensate for the uneven frequency response. So, with RoomPerfect, it can actually be an advantage to choose what's normally regarded as a less ideal "close wall" loudspeaker placement as this will not only improve the impulse response. Also, when compensating for the increased efficiency, the load on both amplifier and loudspeaker is decreased whereby less distortion and better headroom is achieved.

The RoomPerfect module comes complete with microphone, cable and microphone stand - i.e. everything you need to make the calibration.
