Cambridge Audio 840A user manual Operating Instructions, Speaker A/B, Balance

OPERATING INSTRUCTIONS

The 840A has a custom-made display on the front of the unit showing the current status and allowing you to access the 840A System Configure menus. Here you can adjust the listening settings of the amplifier to personal preference. The menu system is easy to navigate and control, simply by using the input select buttons to turn a feature on (solid circle) or off (no circle) and the volume control knob to increase/decrease settings.

Bass and Treble

Bass Treble Direct

These controls allow subtle adjustments to the tonal balance of the sound. Press to release and rotate to adjust (press back in when desired settings found). In the central position these controls have no effect.

These controls only modify the sound through your loudspeakers and the Pre-Out sockets; 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 by the Direct switch. This completely removes them from the signal path for maximum fidelity. If the musical recording is of poor quality or other factors are affecting the sound quality, it may be necessary to adjust the tone controls to compensate.
