3:Customer registration form Operating voltage The SDA 2175 is available in a version for 115V mains voltage and in a version for 230V mains voltage. Check the label on the SDA 2175 rear panel and verify that you have the version with the proper voltage for your area. -
Page 6: Introduction
Lyngdorf Millennium and M2150 amplifiers. Due to the switch-mode topology, with an efficiency of up to 85%, the SDA 2175 will provide its output power with minimal heat dissipation. A massive power supply with a 650VA toroidal transformer and more than 40000 microF capacitors ensures that the SDA 2175 can deliver the current to drive even the most demanding loudspeakers. -

Fig 2: SDA 2175 rear panel. Mains Connector Mains voltage to the SDA 2175 is applied via an IEC320 type connector. The supplied cable with safety ground should be used to connect the SDA 2175 to a mains outlet. WARNING: Connect the power input only to the AC source printed on the label. -
Page 8: Input Connectors
The SDA 2175 has input sockets for both balanced and unbalanced signals, but only one may be used at a time. The XLR and phono sockets are internally connected in parallel, so only one set of the connectors should be connected externally. ALWAYS use EITHER the XLR inputs OR the phono inputs. -
Page 9: Unbalanced Inputs
If there is a plug in the TRIGGER IN socket, the SDA 2175 standby mode is controlled by the voltage on the plug. With no voltage applied, the SDA 2175 will go into standby mode. If a DC voltage of 5-24V or a 50Hz AC voltage of 4-17Vrms is applied, the SDA 2175 will go into OPERATE mode. -
