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.
The BEHRINGER ULTRABASS PRO fits into one standard 19" rack unit of space. Please allow at least an
additional 4" depth for the connectors on the back panel.
Be sure that there is enough space around the unit for cooling and please do not place the ULTRABASS PRO
on high temperature devices such as power amplifiers etc. to avoid overheating.
+
Before you connect your ULTRABASS 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 ULTRABASS 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 mains connection of the ULTRABASS PRO is made by using the enclosed mains cable and a standard
IEC receptacle. It meets all of the international safety certification requirements.
+
Please make sure that all units have a proper ground connection. For your own safety, never
remove or disable the ground conductor of the unit or of the AC power cable.
As standard, the BEHRINGER ULTRABASS PRO is installed with electronically servo-balanced inputs and
outputs. The circuit design features automatic hum rejection for balanced signals, permitting trouble-free
operation even at the highest operating levels. Externally induced power-line hum, etc. is thus suppressed
effectively. The automatic servo function recognizes the presence of unbalanced connectors and adjusts the
nominal level internally to avoid level differences between the input and output signals (6 dB correction).
You will find additional information in chapter 4 “INSTALLATION”.
1.3 Control Elements
Fig. 1.1: The ULTRABASS PRO
The BEHRINGER ULTRABASS PRO provides 5 illuminated push-button switches, 6 rotary controls, and 4
level displays. The ULTRABASS PRO is designed as a stereo processor and is therefore not suited to process
two different signals. The front of the ULTRABASS PRO is divided in three sections, each with its own function.
