The Float QA power supply is the classic solution in case you want to use your own main amplifier to drive the Float`s. Just connect the power supply unit with the speaker out connections of your amplifier. If you want you can connect existing speakers with the speaker out sockets of the power supply. On the frontpanel of the power supply you find a switch to decide if you want to use the Float`s or spekers. Inside the power suply we have the cascade to charge up your Float`s plus 2 large audio transformers to prepare the music signal delivered by the amplifier for the use with the Float`s.
The power supply unit not only can drive the new Float QA but also is a clear benefit to drive older original Float`s.
