11.+/ - – These increment/decrement buttons have different functions, depending upon whether a front panel button is flashing or not. If a front panel button is flashing, they are used to increment or decrement the value of the selected parameter. (For example, if the PRESET button is flashing, the +/- buttons step through the various equalization presets.) If no front panel button is flashing, the +/- buttons adjust the overall system volume. (Press the + button to increase system volume and the – button to decrease system volume.)
In addition, by pressing both the + and – buttons at the same time, they can be used to alter the brightness of all front panel buttons and the Meter Display. There are six settings; at the lowest setting, all buttons and meter segments are completely off, and only the JBL logo glows to indicate power.
