The BEHRINGER MULTICOM PRO fits into one standard 19" rack unit of space (1 3/4"). Please allow at least

an additional 4" depth for the connectors on the back panel. Be sure that there is enough air space around the

unit for cooling and please do not place the MULTICOM PRO on high temperature devices such as power

amplifiers etc. to avoid overheating.

Before you connect your MULTICOM PRO to the mains, please make sure that your local voltage

matches the voltage required by the unit! The fuse holder on the female mains connector has 3 triangular

markers, with two of these triangles opposing each other. Your MULTICOM PRO is set to the operating voltage

printed next to these markers, and can be set to another voltage by turning the fuse holder by 180°. CAUTION:

this instruction does not apply to export models exclusively designed, e.g. for 115 V operation!

The audio inputs and outputs on the BEHRINGER MULTICOM PRO are fully balanced. If possible, connect the

unit to other devices in a balanced configuration to allow for maximum interference immunity.

+Please ensure that only qualified persons install and operate the VIRTUALIZER. During instal-

lation and operation the user must have sufficient electrical contact to earth. Electrostatic

charges might affect the operation of the MULTICOM PRO!
