2.3.2 Front Panel Controls

Notes

Input Level Knob

Caution: This knob should not be used for volume control. It should be approximately 12 o’clock or straight up. The only time it should be turned down is if you notice the LED Level Light going into the red. The unit is then being overloaded and at any output level distortion is being produced.

Bass EQ Knob

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.

2.3.3

The balance of these switches perform the identical function as the remote so please refer to Remote Instructions for their functionality.
