Figure 3: Rack Mounting the Amplifier
Installation
The amplifier is designed for wall mount applications but can also be mounted in a
standard 19" rack. The 250W amplifier weighs 31lb.
NOTE: The amplifier will produce heat during operation which will rise and may
cause problems for temperature-sensitive equipment mounted above it.Mount the
amplifier near the top of the backboard (for wall mounting) or rack (for rack
mounting) so that no other equipment will be above it.If this is not possible, then
allow at least 12" between the top of the amplifier and the bottom of any equipment
positioned above it. Also allow at least 6" between the bottom of the amplifier and
any equipment below it to allow for adequate air circulation.
Wall Mounting To wall mount this unit,use the four 5/8" pan head screws with nylon washers
provided (see Figure 2).Insert the top two screws first leaving the heads protruding
about 1/4". Lift the amplifier and place it over the 2 screws using the top keyhole
slots in the flanges at the sides of the amplifier.Allow the amplifier to rest on the 2
screws and then proceed to insert the bottom 2 screws into the lower keyhole slots.
With all the screws in place,tighten the screws to secure the amplifier.
NOTE:Backboard must be a minimum of 3/8" thick plywood and securely mounted
to the wall.
Rack Mounting The amplifier was designed to mount directly to standard 19" racks using the
mounting flanges as shown in Figure 3 (rack screws are not supplied).In the factory
set position the unit will protrude from the front of the rack.This provides the best
ventilation of the unit and easier access to the wiring connections.
NOTE: The unit can also be mounted partially recessed in the rack by reversing
the mounting flanges.Unscrew the mounting flanges (3 screws mount the flange to
the cover) and install them in a flipped over orientation.This position will provide
adequate ventilation and centers the weight of the unit over the rack rails.
