Over Temp LED — Lights red when the amplifier has exceeded the maximum recommended operating temperature. The

Power limiting may or may not be applied at this point. This depends on the temperature of the unit.
Removable Plastic Grilles (2) — The removable plastic grille assembly is secured to the steel front chassis by two tabs on
5
the inner edge that hook under the center UI section and are held in place by a neodymium magnet on the outside edge. The
grilles are removable by inserting the included plastic removal tool into the front panel groove and pulling forward.
Each plastic grille covers a foam air filter. The filters are held in place inside the grille by crush ribs along the inside edges of
the grille.
To replace the filters, remove the grille from the front panel by inserting the included plastic pry tool, flathead screwdriver, or
other small flat object into the groove along the outer edge of the grille and pulling forward. Remove and wash or replace the
filter.
