Extron Electronics SSP 7.1 User Guide - Manual (Page 9)

Test signals for setup and calibration — The SSP 7.1 generates test signals, including
band-limited Dolby noise and full-bandwidth pink noise, to facilitate calibration of sound
pressure levels from all speakers, and to fine-tune the interaction of a speaker with the
acoustical environment. The SSP 7.1 also offers the option to use an external source for test
signals, which can then be directed to any speaker, or all speakers in sequence.
Speaker compensation delay — The signal to each output channel can be individually
delayed so that the sound from all speakers is synchronized when it reaches the listener.
Lip sync offset — This feature delays an audio signal so that it is resynchronized with a
video signal that has been delayed by video processing. The offset can be applied to each
input channel independently.
Equalization — Nine bands of parametric EQ are available to enhance tone, compensate
for differences in individual speaker output, and adjust frequency response for a given
acoustic environment.
