Adjusting amplifier settings
It is possible to adjust the audio equalisation of the amplifier to suit a specific
environment or taste. There are separate settings for the internal Jukebox
speakers (Channel 1/2) and any additional speakers that may be connected
(Channel 3/4).
Pressing the MENU UP or MENU DOWN buttons on the D4 amplifier will cycle
through the available menus. Pressing the ‘+’ or ‘-‘ buttons will increment or
decrement the value of the current menu. Any changes will be automatically
saved. (The location of these buttons is shown in Fig 7 on page 21) If no buttons
are pressed for 1 minute, the amplifier will revert back to its default display
mode.
Below is a description of the available menus:
• Channel 1 Stereo / Mono Switch
This menu is used to set the amplifier in Stereo or 2 channel Mono. This
should be left as ‘Stereo’.
• Channel 1 Master
This menu sets the maximum volume level that can be achieved with
the remote and should be used to set a maximum level for the Jukebox
speakers.

or boost of 15dB.
