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 COMPOSER. During
installation and operation the user must have sufficient electrical contact to earth. Electro-

5.4 Selecting the operating level
The BEHRINGER TUBE COMPOSER allows you to switch the internal operating level with the OPERATING
LEVEL switches on the rear panel of the unit. Thus, you can choose between the homerecording level
(-10 dBV) and the professional studio level (+4 dBu). With this adjustment, the TUBE COMPOSER is adapted
to the optimal operating level. Use the input level meter on the front panel to find the appropriate operating
level.
5.5 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.
