protect the unit from rough handling. Nevertheless, we recommend that you carefully examine the packaging
and ist contents for any signs of physical damage, which may have occurred in transit.

If the unit is damaged, please do not return it to us, but notify your dealer and the shipping
company immediately, otherwise claims for damage or replacement may not be granted.
Shipping claims must be made by the consignee.
3.1 Rack Mounting
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.
3.2 Mains Voltage
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!
3.3 Audio Connections
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!
