ISP Technologies VMAX 150C - Manual (Page 4)

PLACEMENT
The VMAX is designed to sit on the floor or stage in a flat position and can also be used as a
top box in a standing position or pole mounted. Do not position or mount the cabinet where it
can tip over and fall on someone. Do not attempt to ‘fly’ (suspend by cables, chains, ropes,
etc.) the cabinet. Do not attempt to suspend the cabinet from the handles. It was not
designed for flying. Position it only on a flat, stable surface where it is not in danger of tipping
over or falling.
Also, note that the placement of the cabinet relative to floors and walls will affect the low
frequency response (below about 500 Hz.). Placing it closer to the floor and walls will
reinforce the low frequency response. The closer it is, the higher in frequency this
reinforcement will go. When used as a top box make sure that adequate space (at least 6
inches) is left on the heatsink side of the cabinet to allow for adequate airflow over the
amplifier heatsink.
