Connecting your Soundboard
Installing the Soundboard is a very simple and
straightforward procedure. To plug it in, simply
connect the left and right channels of the amp
to the left and right terminals on the back of
the Soundboard, as on traditional loudspeakers.
Be very careful to respect the polarity (according
to standard practice by which the red wire
is connected to the + and the black wire to the -)
and to avoid reversing the colours of the plugs and
the terminals. The red plugs must always be fitted
in the red terminals and the black sockets in the
black terminals, just as you will do on the amp.
First connect the Soundboard and then the amp
in order to avoid any risk of a short circuit.
Now that the Soundboard is plugged in, check that the cables are not touching the cover. If this is
the case, you can hold the cables together with a dedicated grip. You can now switch on your amp and
listen to your favourite music.
Important note
When you first begin to use it, the Soundboard generates rather discreet bass tones. You may chose
to enhance them for a certain period of time using the amp, providing it is equipped to do so, but you will
soon see that the Soundboard is gradually enriched with bass tones.
