ULSI
ULSI stands for Ultra Linear Stereo Image. ULSI is a new stereo technique invented and developed by Erik Sikkema and propriety to Erik Sikkema Studio, but available to any label or enduser. The technique is mainly invented to overcome the general problems of most common stereo techniques in organ recordings, but the effect is stunning aswell on a wider spectrum of other instruments and combinations.
Advantages of ULSI in comparison to standard stereo techniques are:
1. More natural sound balance in the lower octaves and a more precise stereo image.
2. Less low frequency disturbance from harpsichord-, piano- and organ keyboard and pedal actions.
3. A more natural dynamic behaviour.
4. Singers and instrumentalists blend better together without any spot microphones at all, which improves the stereo depth enormously.
5. No hearing fatique, no pressure on the ears.
6. Listening with headphones, gives a very pleasant sound, very similar to Dummy Head stereo recordings.
7. Enjoyable also on very low listening levels of your amplifier at home.
8. Sounds also very convincing on simple and cheap equipment.
Its claims are true, there is a very much more precise and solid stereo image and an easy effortlessness to the sound, it becomes even more of a joy listening to sounds of this wonderful organ.

This organ is a reconstruction of the original instrument from
1608 built by Paul Müller. That organ was sold in two parts and
placed in Övertorneå and Hedensäset, Sweden. In one church
the Hauptwerck is still used, in the other church the Rückpositief
is still played. This reconstruction was realized by Grönlunds in
Gammelstad, Sweden. www.gronlunds-orgelbyggeri.se
