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. The warranty will not cover any damage caused by connecting to the wrong type of AC mains.

Loudspeaker connectors

The SDA 2175 loudspeaker connectors accept banana plugs, spades or bare wire ends up to 5 mm in diameter. Connect the wires from each loudspeaker to each channel's + and – terminals. Do not make any other connections to the output terminals. The loudspeaker cable is inserted into the slot in the loudspeaker terminal and the terminal is tightened firmly.

WARNING: Always disconnect the SDA 2175 from the mains before changing any connections to its inputs or outputs.

When the SDA 2175 is operating, there is 35V DC on its output terminals with reference to ground.
