The amplifier has a dedicated microphone input that is setup to accept a low impedance
(~600
Ω ) passive microphone. Active or wireless microphones can be used but any
external gain controls should be set low.
Line Output
The amplifier provides a stereo line level audio output for connection to other amplifiers,
if required the microphone signal can be output separately.
Slave Input
If 2 D2 or D4 amplifiers are used together a special link between the Line Output of the
first amplifier and the Slave Input of the second amplifier can be made. This link will
configure the second amplifier as a slave and adjust all internal settings accordingly.
Features which can not be used on a slave amplifier, such as the auxiliary inputs, will be
hidden.
Using the Amplifier
By default the amplifier LCD display will show the active input along the top line and the
Remote Volume Control (RVC) level along the bottom line.
On the D4 amplifier, the display will show the RVC level for channels 1 and 2 for 10
seconds and then show the RVC level for channels 3 and 4 for 10 seconds.
To change the settings on the amplifier a simple 4 button system is used.
Pressing the Menu Up button or the Menu Down button will cycle through the different
menus, using the + or – buttons will increment or decrement the current menu.
The display will return to its default state, showing the active input and RVC levels, if no
buttons are pressed for 1 minute. When the display returns to this state any changes to
the menus will be saved.
Menu Description
The following is a list of the different menus and their functions:
Channel 1 Stereo Mono Switch (Shown as Channel 1/3 on the D4)
This menu is used to set the amplifier in Stereo or 2 channel Mono
For most installs the amplifier should be left in Mono which will give independent control
of each channel.
If the appropriate speakers are installed the amplifier can be used in stereo, all settings
for channel 2 will now be taken from channel 1 and the volume for both channels will be
controlled from a single RVC control.
On the D4 amplifier channels 3 and 4 are also linked as a stereo pair.
If the amplifier is set in stereo all controls for channel 2 are hidden, on the D4 amplifier
this applies to channel 3 as well.
Menus 2 to 6 are repeated for each channel, the top line of the display will show which
channel is currently selected.
