130 DeepMind 12 User Manual 14. Connection Wiring Diagrams The DeepMind 12 analog polyphonic synthesizer uses servo-balanced outputs. The circuit design has an automatic hum suppression with balanced signals and is able to operate, without problem, even at highest levels. Externally-induced mains hum etc, is thus efficiently suppressed. The servo-function, also automatic, recognizes the connection of unbalanced pin assignments and changes the nominal level internally so that there is no difference in level between the input and output signals (6 dB correction) Caution: Please ensure that only qualified persons install and operate the device. During installation and operation the user must have sufficient contact to earth. Electrostatic discharges might affect the operation of the unit.
