The 500-HP can be flown or ground- stacked with MINA arrays using the optional MTF-M’elodie/ MINA transition frame. For applications requiring more low- frequency headroom, Meyer Sound’s 600-HP and 700-HP subwoofers are ideally suited for integration with MINA sys- tems.

MINA OPERATING INSTRUCTIONS Amplifier Cooling System MINA’s amplifier relies solely on natural convection for cool- ing from air flowing over its heat sink. The efficient design of the amplifier and heat sink profile keeps temperatures low, even when the unit is used at high ambient temperatures in tightly packed conditions, and when driven continuously at high output levels. CAUTION: The MINA heat sink can reach tem- ! peratures of up to 85° C (185° F) during extreme operation. Use extreme
