General information

Interacoustics continuously strives to improve its products and their performance, therefore the specifications can be

subject to change without notice.

The performance and specifications of the instrument can only be guaranteed if it is subject to technical maintenance

at least once a year. This should be done by a workshop authorized by Interacoustics (refer to calibration procedure on

page 26).

¹The Binaural to Monaural correction on +2dB come from ANSI S3.6 -2004

The difference between 0° - 45° - 90° come from ISO 8253-2 1998.

The maximum free field levels depend on the amplifier, speaker and the acoustic conditions of the room. The actual maximum levels are found

using the Custom Max function in the calibration software.
