INSTALLATION

The 311 may be used in a wide variety of applications and

environments. Enclosed in a rack-mountable, all-steel enclosure, the

unit is designed for continuous professional use. Mounting location is

not critical. However, for greater reliability we recommend that you not

place the unit on top of power amps or other sources of heat.

AC POWER HOOKUP

The 311 has an internal power supply designed to operate at 115

VAC @ 50 to 60 Hz. Units manufactured for use outside the United

States of America have been modified to comply with the required

electrical specifications.

Before plugging the 311 into the main AC line, make sure that all of

the equipment following the crossover outputs, are turned off or all of

the outputs are turned down.

ANALOG AUDIO CONNECTIONS

Audio input connections to the 311 are balanced XLR (Pin 2 = Hot

(+), Pin 3 = Cold (-), Pin 1 = Ground) and ¼” phone plug (Tip = Hot (+),

Ring = Cold (-), Sleeve = Ground). All output connections are

unbalanced ¼” (Tip = Hot (+), Sleeve = Ground).

SAFETY PRECAUTIONS

Warning: To avoid the risk of shock or fire, do not expose this unit to

moisture. Refer all servicing to qualified personnel. Do not remove the

metal cover; there are no user-serviceable parts inside. When

applicable, only use the power adapter that came with this unit or one

obtained from ART’s Customer Service Department.
