1.2 Before you begin
Your BEHRINGER ULTRA-DYNE PRO was carefully packed in the factory and the packaging was designed
to protect the unit from rough handling. Nevertheless, we recommend that you carefully examine the packag-
ing and its 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.
The BEHRINGER ULTRA-DYNE PRO fits into two standard 19" rack units of space (3 1/2). 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 ULTRA-DYNE PRO
on high-temperature devices such as power amplifiers to avoid overheating.
+
Please ensure that the ULTRA-DYNE PRO is set to the correct supply voltage before connecting
the unit to the power supply system!
The AC power connection of the ULTRA-DYNE PRO is made using a standard power supply cable and 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 ULTRA-DYNE 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).
The optional digital input and output (AES/EBU interface) connections are balanced with a negative ground.
High-quality connectors ensure isolated, noise-free signal throughput. The MIDI connections (IN/OUT/THRU)
have been realized with standardized DIN plug-in connectors. Optocouplers have been used for isolated data
communications.
