ULTRABASS BX300

1.2 Before you begin

Your BX300 was carefully packed in the factory and the packaging is designed to protect the unit from rough
handling. Nevertheless, we recommend that you carefully examine the packaging and its contents for any
signs of physical damage, which may have occurred during transit.
+If the unit is damaged, please do not return it to BEHRINGER, 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.
Be sure that there is enough space around the unit for cooling and please do not place the ULTRABASS on
high-temperature devices such as radiators etc. to avoid overheating.
+Before you connect your ULTRABASS 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 markings, with two of these triangles opposing
each other. The ULTRABASS 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!
Please use the enclosed power cord to connect the unit to the mains. The cord complies with all applicable
safety standards.
+Please note that all units must be grounded properly. For your own safety, you should never
remove any ground connectors from electrical devices or power cords or render them
inoperative.
You will find additional information in chapter 4 INSTALLATION.
