Time alignment for the listener’s position
To achieve a perfect phase reconstruction, at the actual position of the listener, the
delays of the transducers must be adjusted carefully. The position of the tweeter has
to be mechanically adjusted, so that a plane wave will leave the speaker system
exactly in the direction to the listener's ear. This is possible owing to the specific
design of the ASCENDO Systems. The displacement of the high frequency Unit
ensures the correct phase in over-floor positions between 50 cm and 190 cm.
1. Switch off the power amplifiers and disconnect all cables of the System ZF-3
2
.
Place the high frequency unit upside down on a soft towel.
3. Loose the 4 screws (7) that fix the steel mounting bars (2) at the unit. Take care not
to remove the screws fully. Apply 2-3 rounds only.
Warning
Don’t open the screws (7) too many rounds! The screw may loose the contact to the Low-
Frequency unit.
4. Move the steel bars (2) to the right position (see section 5.1).
5. Fix the screws (7) again.
