55.. PPOOWWEERR//SSTTAATTUUSS LLEEDD
Located on front panel this LED illuminates green when the Power Switch is in the “ON” position and AC power is
supplied. During normal operation the LED also acts as a DDT indicator. The LED illuminates red when the DDT
speaker protection is active. When DDT is defeated, the LED will illuminate red when clipping occurs.

Provides a preset boost to treble frequencies when pressed.
