Cambridge Audio Azur 840EW user manual Operating instructions, Pre-amplifier setup

Operating instructions

The 840E has a custom-made display on the front of the unit that shows the current status and allows you to access the 840E System Configuration 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.

Volume

Mode

Volume

Adjust the volume control knob on the front panel (or using the remote control). The display will show the change in volume in decibels (dB). ‘OdB’ indicates maximum volume while lower volume settings progress into the negative range. This can also be changed to arbitrary volume units (0-96) in the System Configure menu.

Balance, Bass, Treble

Mode

Volume

Press the Mode button to scroll through the options of Balance, Treble or Bass modes. BALANCE, TREBLE or BASS will appear on the display depending on which mode you have entered. Adjustments can then be made using the volume control. This allows subtle adjustments to the tonal balance of the sound. These modify the sound through your loudspeakers and the Pre-Out sockets only; they do not affect the signals sent through the Tape Out connections.

Press the Mode button again to return to Volume mode or wait 5 seconds for the 840E to automatically exit and return to Volume mode.

Direct

With a well produced CD and a good system the tone controls are unnecessary and can be switched out by pressing the Direct button:

Direct

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, you can adjust the tone controls to compensate. To use the tone controls press the Direct button so that the Bass/Treble icon ( ) lights in the display indicating that they are active and direct mode is Off.

The 840E stores whether Direct mode is on or off for each input individually. For example it is possible to have the tone controls automatically active for the Tuner source but not the CD source.

Pre-amplifier setup

The 840E features many advanced settings that allow its use to be customised to user preference. The inputs can be named to reflect the actual source units you have, each input can be trimmed so that each sounds the same in terms of loudness when you switch between them and other options.
