1.4 INSTALLATION
Before proceeding, thoroughly inspect the amplifier for signs of physical damage that may have been
incurred during shipment and completely read the following installation and operating instructions, paying
special attention to all
CAUTION notes.
1.4.1 Location
Select an operating location that will permit air to circulate freely around the amplifier’s cabinet. The
Model 25A250B utilizes air cooling and should be located where the normal flow of air into or exiting from

air exiting the rear of the amplifier should not be impeded.
Do not position the unit next to a wall or other equipment that would restrict the flow of air into the bottom
of the unit or out of the rear of the unit.

CAUTION:
Dangerous voltages are present in the Model 25A250B whenever the unit
