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 250U1000 utilizes air cooling and should be located where the normal flow of air into or exiting from
the unit will not be restricted, diverted, or re-circulated through the unit itself; in particular, the flow of warm
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.
1.4.2 Power
The Model 250U1000 is designed to operate using AC primary power of 100–240 Volts Alternating Current
(VAC), 50–60 Hz single phase, 700 watts maximum.
CAUTION:
Dangerous voltages are present in the Model 250U1000 whenever the unit
is plugged into an AC outlet. Always disconnect the unit from the main
power line when servicing it.
