and the receiver.
•
Adjust the speaker level.
•
Measure the distance of each speaker to your
listening position.
•
Measure the speaker polarity.
•
Measure the speaker size.
•
Measure the frequency characteristics.*
*
•
DTS 96/24 signals are always played back as 48
kHz when you correct signals.
•
The measurement result is not utilized for
signals with a sampling frequency of more than
96 kHz.
The DCAC is designed to obtain proper sound
