Warning: To avoid the risk of shock or fire, do not expose this unit
to moisture. Do not remove metal panels from chassis parts.
Removing the chassis from its cabinet parts exposes dangerous
high voltages. There are no user-serviceable parts inside. Refer all
servicing to qualified personnel. Note: If your power cord
becomes damaged and must be replaced, always replace it with
the proper type (3 prong.)

When the rear panel power switch is turned on, the power indica-
tor LED will illuminate. It is important to remember to turn the Tube
PAC on before any monitoring levels or power amps are turned
on. The Tube PAC has the ability to add over 60dB of gain to its
input signal. This can cause the Tube PAC to produce a "thump"
on power up and power down.
N N o o t t e e : : Like all tube-based equipment, the Tube PAC needs to warm
up before being used. Allow one to two minutes for the tubes to
reach proper operating temperature before using.
If the Tube PAC fails to power up when the power switch is turned
on, check to see that its power cord is plugged into an active out-
let. If the unit still fails to operate properly, turn it off and unplug
it. Then consult your dealer or A R T's Customer Service depart-
ment.
