PERFORMING

MULTI-POINT

MEASUREMENTS

One of the most advanced features of the SDP-75 is its unique multi-point measurement technology.

Instead of using an averaged response out of multiple measurement points, the Trinnov Multi-point

Algorithm is able to take every single measurement point into account.

The purpose of multi-point measurement is not only to optimize a wider listening area but also to get
more information from measurements and increase reliability by taking into account important
variations in the listening area.

NOTE:

The multi-point approach ensures a more reliable calibration but choosing relevant microphone

positions is highly critical.
