DUALFEX PRO EX2200

Surround processor

A switchable surround processor has also been integrated into the DUALFEX PRO. With this processor the intensity of the stereo effect can be dramatically improved. The program material gains in liveliness, depth and transparency. As in a cinema with its special acoustics, the listener has the impression that the orchestral instruments are placed all around him. The surround processor enlarges the stereo basis, dependent on the program material, without audibly coloring the sonic image.

1.2 Before You Begin

Your BEHRINGER DUALFEX PRO 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.

The BEHRINGER DUALFEX 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 space around the unit for cooling and please do not place the DUALFEX PRO on high temperature devices such as power amplifiers etc. to avoid overheating.

+Before you connect your DUALFEX 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 DUALFEX 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 DUALFEX 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 DUALFEX PRO is installed with electronically servo-balanced inputs and out- puts. 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 “AUDIO CONNECTIONS AND INSTALLATION”.
