State of the art performance combined with unique operating features sets the Quad 99 Pre Amplifier apart from competing products. The combination of universal phono-socket connectors and Quad Link inputs gives the ability to connect an almost unlimited number of sources, each with optimal matching. All inputs, including those for moving-coil and moving-magnet cartridges, have adjustable sensitivity. This flexibility also extends to the wide range of precise tone control adjustments that can be made. In addition to the usual high-frequency filter, there are adjustments for the bass response, and the unique Quad ‘Tilt’ control which skews the entire frequency response to give a preferred tonal balance.
