Give analogue inputs are present, giving a good level of flexibility in regards to connecting your various audio sources. A phono input is present, allowing you to connect a turntable directly to the amplifier without the need for an external phono stage. A tape output and subwoofer feed are also provided, and a remote control is provided to make the overall listening experience an easy and immersive process.
