POWERPLAY PRO HA4600

4. AUDIO CONNECTIONS

As a standard, the BEHRINGER POWERPLAY PRO is equipped with electronically servo-balanced inputs
and outputs. The circuit design features automatic hum suppression for balanced signals and so ensures
trouble-free operation, even at the highest operating levels. Externally induced mains hum, etc. can therefore
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
(6-dB correction).
