This is a 120-watt power supply, providing 120W at 20V. While you can also use it with the Amp2, we recommend it specifically for the Beocreate 4 channel amplifier with larger speakers (for small speakers like a CX50 the smaller 60W power supply is powerful enough). The quality is very good—as you would expect from a Meanwell power supply.
The power supply works with 100-240V mains voltage. As power cables are different in many countries, we provide it without a mains cable.
