Bass and treble tone controls
These controls allow subtle adjustments to the tonal balance of the sound. In the central position these controls have no effect. These controls only modify the sound through your loudspeakers and the Pre- Out sockets (where featured), they do not affect the signals sent through the Tape Out connections. With a well produced CD and a good system the tone controls are unnecessary and can be switched out. If the musical recording is of poor quality and/or the loudspeakers/surroundings are lacking it may be necessary to adjust the tone controls to compensate.
