Operating instructions

INSTALLATION
The ART CX311 may be used in a wide variety of applications and environments. Enclosed in a 1U
(1.75 inches high) rack-mountable, all-steel enclosure, the unit is designed for continuous
professional use. The depth is 5 inches. 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 CX311 has an internal power supply designed to operate from 105 to 120VAC at 50/60Hz. Units
manufactured for use outside of the United States have been modified to comply with the required
electrical specifications for the country of destination. Before plugging the CX311 into the AC mains,
make sure that all of the equipment following the crossover outputs are turned off or that all of the
outputs are turned down.
INPUT/OUTPUT CONNECTIONS
The CX311 has XLR and 1/4" TRS phone jack connectors for each input. Audio input connections are
active balanced although the 1/4" phone jack connections can easily be converted to unbalanced
operation by using two-conductor phone plugs. All output connections are unbalanced and use 1/4”
TS phone jacks.
