A vertical rack space of 2U (88mm high) is required, with an in rack depth of 18.1 inches (460mm).

The amplifier protrudes 1.6 inches (40mm) from the rack supports.

Mounting & unit dimensions

If the unit is likely to undergo extreme vibration through trucking and touring, front rack ear reinforcement brackets and rear mounting plates must be fitted. These are available from your dealer. Damage caused by insufficient support is not covered by the warranty.

To prevent damage to the front panel finish, always use protective plastic cups or washers underneath the rack mounting bolts.

Ventilation gaps between units are not required, however care must be taken to ensure that an unobstructed free flow of clean air is possible from the back of the unit to the front. It is important that neither the rear air intakes or front exhaust grilles are covered. The internal airflow of all PULSE amplifiers is designed to minimize contamination of the electronics by the cooling air so fan filters will not normally be required. If however, the amplifier is to be used in an environment where the intake air might be excessively dirty, optional external fan filters should be purchased from your dealer. Fan filters should NOT be fitted unless there is likely to be a problem as they require regular cleaning to stop them getting clogged. Clogged fan filters will result in the amplifier going into premature temperature protect.

PLEASE NOTE: Users must ensure that glycol based smoke and related substances are not allowed to enter the amplifier (fan filters will not help). Glycol based smoke is HIGHLY corrosive and prolonged exposure will cause irreparable damage to your amplifier.

Do not expose the amplifier to rain or moisture during either operation or storage. If the unit does come into contact with moisture, remove the AC power cord immediately and leave it in a suitably dry, warm place to dry out.

Be aware that when any equipment is taken from a cold location into a hot humid one, condensation may occur inside. Always allow time for the equipment to attain the same temperature as its environment before applying the AC power cord.
