BALANCED INPUTS

As standard, the DS48 comes with electronically servo-bal- anced inputs. This circuit design features automatic hum and noise reduction for balanced signals and thus allows for trou- ble-free operation even at high operating levels. Externally induced mains hum etc. will be effectively suppressed. The automatic servo-function rec- ognizes the presence of unbal- anced connectors and adjusts the nominal level internally to avoid level differences between the input and output signals (correction 6 dB).
