MULTIGATE PRO XR4400 User Manual

The philosophy behind BEHRINGER products guarantees a no-compromise circuit 

design and employs the best choice of components. The operational amplifiers 

NJM4580 which are used in the MULTIGATE PRO, are exceptional. They boast 

extreme linearity and very low distortion characteristics. To complement this 

design the choice of components includes high tolerance resistors and capacitors, 

detent potentiometers and several other stringently selected elements.
For the first time, the MULTIGATE PRO XR4400 uses SMD technology 

(Surface Mounted Device). These sub-miniature components known from 

aerospace technology allow for an extreme packing density, plus the unit’s 

reliability could be improved. Additionally, the unit is manufactured in 

compliance with a ISO9000 certified management system.

2.2.1  Balanced inputs and outputs
As standard, the BEHRINGER MULTIGATE PRO is installed with electronically 

servo-balanced inputs and outputs. The new circuit design features automatic 

hum and noise reduction for balanced signals and thus allows for trouble-free 

operation, even at high operating levels. Externally induced mains hum etc. 

will be effectively suppressed. 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 (correction 6 dB).

Your BEHRINGER MULTIGATE 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 packaging and its 

contents for any signs of physical damage, which may have occurred in transit.

Please take the time to complete and return the warranty card within 14 days of 

the date of purchase, otherwise you will lose the right to the extended warranty. 

Or just use our online-registration (behringer.com).

The BEHRINGER MULTIGATE PRO fits into one standard 19" rack unit of space 

(1 ¾"). 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 MULTIGATE PRO on high temperature devices such as 

power amplifiers etc. to avoid overheating.

unit! The fuse holder on the female mains connector has 3 triangular 

markers, with two of these triangles opposing each other. Your MULTIGATE 

RPO 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°. 

The audio inputs and outputs on the BEHRINGER MULTIGATE PRO are 

fully balanced. If possible, connect the unit to other devices in a balanced 

configuration to allow for maximum interference immunity.
