Treble
Press the treble button on the hardwired controller or wireless remote.
A blue EQ LED will illuminate next to the treble button. When using the
hardwired controller, turn the master volume knob clockwise to
increase the treble and counter-clockwise to decrease the treble.
When using the remote, press and hold “+” button to increase the
treble or press and hold the “–” button to decrease the treble.
An LED will light up and move on the wired controller to indicate
changing treble levels. The LED will reside in the far right position for
maximum treble and in the far left position for minimum treble.
After a few seconds, treble will default back to main volume. To return
to treble control, press the treble button again.

controller or wireless remote. The blue LED located next to the power
button will turn off. To un-mute, press the stand-by button again.
