The 4 watt integrated amplifier expects speakers with an impedance of 8 ohms. So if the customer for example has 2 x 4 ohm speakers these will need to be connected in series to get the 8 ohms required for the correct impedance matching. The snom PA1 has basic speaker connections on the back as well as the 3.5 mm jack. The speaker wires can just be plugged into that. Use the 3.5 mm connection as a line out connection to amplifier and speakers.
