Please note, the switch is sold here without any power supplies. In some cases the box will contain a power supply, but it is not part of this offer and not included in the price because these power supplies are for Europe use (220V) and may require a power converter to (110V) and plug adapter to operate in the USA. That is why we are saying, you are only buying the switch here.
Remember to turn your receiver OFF (using the Power OFF/ON switch) before connecting or disconnecting a splitter/switch/tap. Damage as a result of connection to a powered receiver will void your one month warranty. Switch is guaranteed not to be DOA (Dead on arrival). See return policy about switches.
