A grille with foam filters is located on the front panel to prevent dust from entering the amplifier. The 
grille is removable for easy cleaning of the filter by simply pulling them off. The foam filter should always 
be used.

Both handles can be used to carry the amplifier; they also act as protection for the front panel. In fixed 
installations or where rack front covers are too shallow, they may be removed by unscrewing the 
retaining bolts behind the front panel.
