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
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
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:
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.
Changing input names / source naming
Mode
Press and hold the relevant input select button for four seconds to
Volume
change its name. For example, if Input 1 is a CD player, name it "CD" etc.
Letters are selected by turning the volume control to scroll through the
available characters. Press LEFT or RIGHT to select which character you
wish to edit. Press EXT CHAR to access an extended character set. Press
OK to confirm and exit the input name change menu.

Volume ramp
Mode
The 840E automatically ramps the volume down when going into

feature off, press the VOL RAMP input select button in the System
Configure menu and set to off. Press the Mode button to exit.

To change the volume display from decibels (-95 to 0dB) to arbitrary
volume units (0 to 96 units) select VOL DB in the System Configure
menu. Press the input select button to turn off the volume in decibels.
