TUBE ULTRAGAIN T1953
5.3 Audio connections
As standard, the BEHRINGER TUBE ULTRAGAIN is installed with electronically servo-balanced inputs and outputs. This 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).
+Please ensure that only qualified persons install and operate the TUBE ULTRAGAIN. During installation and operation the user must have sufficient electrical contact to earth. Electro- static charges might affect the operation of the TUBE ULTRAGAIN!

5.4 Transformer-balanced output (option)
In contrast to electronic balancing, the use of transformer-balanced outputs offers the advantage of galvanic separation between units. Electrical potential differences and ground loops in audio installations do not therefore impair the performance of the units. The transformer-balanced outputs, commonly used in radio and TV engineering, can also be fitted retrospectively upon request. The BEHRINGER transformer OT-1 is designed to the highest exacting standards and is available as an accessory.
