JBL Synthesis - Manual (Page 10)

2.1.5 Woofer Equalization
While the JBL Synthesis System is calibrated to provide
awesome amounts of clear, clean bass, some listeners
might prefer a touch more bass for some sources. This
cannot be adjusted from the Remote Controller, but must
be done using the BASS EQ dial to the left of the
INPUT control on the Surround Processor.
The preset bass is encoded at the off or zero position. To
boost the bass level, slowly turn the dial clockwise a
little at a time until it meets your auditory needs. A full
17 db of boost is available, so go slow to avoid
shocking the equipment or your ears.
