Hi, I bought the Mirage FRX-9 trough Ebay and they were just delivered. At the site and in the manual of the speakers it is stated that the internal amplifier of the speaker can use 110 Volts or 240 Volts (which is regular in Europe). But at the back side of the speaker I only see 110 Volts mentioned. Is it OK to connect the speakers directly to the power supply of 240 Volts at my home?
