Introduction
The JMC Soundboard is a full-fledged musical instrument stemming from 21st century lutherie
techniques.
It is thus very important to take great care of it, in terms of packaging (resonance spruce is very soft
and thus easily marked); humidity (at least 40%); and exposure to sources of heat (avoid placing it near
a fireplace, a radiator or positioning it behind a window in direct sunlight).

Choosing the location of your Soundboard
The Soundboard is a plane-type loudspeaker that creates a hemi-directional wave. This means that
the sound is perceived in the same way whether one is near or far away from the audio device - and that
you are thus free to choose where to locate the Soundboard. This may be determined by the aesthetic
appearance of the audio system and by the interior design of the surroundings. It is nonetheless important
to be sure not to place it too close to a source of heat and at a reasonable distance from the amplifier.
It adapts perfectly well to open two-floor areas as well as L or U-shaped settings.
The Soundboard works well whatever the size of the room in which it is used. While it is extremely effective
in a large living room, it can also fill spaces of up to 400 m2in music listening situations. One may
of course also opt to install several Soundboards.

Installing your Soundboard
You can choose between three different sorts of fixture. While it is generally fixed against a wall, you may
for space -or acoustic- related reasons choose to install it in the corner of a room thanks to a longer arm serving
to place it in an angle. The latter position will generate more bass tones. If the structure of the room does not
enable wall mounting, the Soundboard may also be placed on a dedicated stand.
The Soundboard should ideally be placed between 1.2 and 1.5 m above ground level (fixing it too high might
make you lose the sense of companionship you establish with it).
You must also take account of the structure of the wall against which it is mounted (wood, plaster, concrete,
bricks); and each material requires its own screws (and safety precautions!). Before drilling, consider any
potential electrical wiring or water pipes that may be hidden inside the wall.
It is necessary to install the JMC Soundboard with two persons.
1. Use a pencil and the supplied template to mark the exact spots of the 4 screws (not supplied) for the fixation
element.
2. Drill the holes for the screws and plugs, if necessary. Be sure to select well adapted plugs in relation to
the material of the wall material. The binding must be robust and not sensitive to vibrations (figure 1).

3. Loosen the lower screw on the fixation element (figure 2).
4. Insert the adjustment tool (figure 3) on the fixation element (figure 4) and set it horizontally, first by adjusting
the level and secondly by firmly pressing the two horizontal bars of the tool against the wall (figure 3).
5. Block the lower screw (figure 2) by using the provided 4 mm Allen screwdriver (figure 5).
6. Remove the JMC Soundboard from the box and place it flat on the floor.
Attention, spruce wood is very tender and can easily be marked.
7. Prepare the 4-wire speaker cable. For installations with visible cables, place
the cable in the ring of the fixation element (figure 6), and insert the plugs
on the back of JMC Soundboard. In the case of an in-wall cable installation,
use the hole in the wall fixation and then move it into the ring.
8. Remove the protective rails, and slide the female part of the fixation located on the back of the
JMC Soundboard into the fixation element on the wall until it is completely fixed. Insert the speaker
cable plugs into the JMC Soundboard. It is recommended to connect the cable before attaching the
JMC Soundboard against the wall, because access to the rear can become difficult at a later stage...
9. Tighten the 2 screws of the female part of the fixation element (figure 6) using the supplied tool (4 mm Allen
screwdriver, Figure 5). This tightening is only possible with the supplied tool.
Now the installation is complete and you are ready to enjoy your musical instrument of the 21st century.
Remark
- The JMC Soundboard is suspended so as to enable the vibrations to travel throughout the membrane (and
not be dissipated through the wall mount or in the wall). It should therefore normally enjoy a certain degree
of freedom when suspended.

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.
