Operating instructions

CHAPTER 3

NOTE: In the highly unlikely event that the

secondary fan does not keep the tempera-

ture below 85˚ C, the 600-HP automatically shuts

down until AC power is removed and reapplied. If

the 600-HP shuts down again after cooling and re-

applying AC power, contact Meyer Sound for repair

information.

Despite the 600-HP’s ﬁltering, extensive use or a dusty op-

erating environment can allow dust to accumulate along the

path of the airﬂow, preventing normal cooling. To prevent

this, you should periodically remove the grille frame, air-in-

take foam and ampliﬁer module and use compressed air to

clear dust from the grille, foam, fans, and heatsinks. Make

sure that the air ducts are clear.

CAUTION: Be sure to unplug power to the

unit before cleaning the ampliﬁer.
