Vinyl records have become all the rage again but you may encounter a couple of issues which are addressed by this unit: Firstly, vinyl records are manufactured in a way that requires frequency equalisation of the turntable output to make them sound right. Secondly, if your amplifier doesn’t have a phono input then you won’t be able to listen to your records. There is a front panel switch to choose between input devices and a volume control on the front panel to adjust the output level as necessary as your turntables' cartridge may provide a lower or higher output than expected. All connections are made with the popular RCA connectors. Power is provided by an included mains adaptor.
