Page 6: Introduction
Introduction The JMC Soundboard is a full-ﬂedged musical instrument stemming from 21 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).
Page 7: Choosing The Location Of Your Soundboard
Soundboard wave Twin-loudspeaker wave 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 m in music listening situations. One may of course also opt to install several Soundboards.

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).

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...

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.
Page 11 Standard installation Connection diagram single (stereophonic) Soundboard Impedance 8 to 16 Ohms The Soundboard is a single stereophonic loudspeaker and two loudspeaker cables must therefore be plugged into the Soundboard (as if there were two traditional loudspeakers). www.jmclutherie.com Page | 11...
Page 12 The amp must be able to handle a 4-Ohm impedance. If such is not the case, opt for the installation suggested on the next page. Connecting both sides of the Soundboard in parallel (side-by-side) as shown above or in series (end-to- end) means it operates in monophonic mode and one can thus place two Soundboards in a room like a pair of speakers.

« Thank you very much for the quick delivery. Installing it was so simple that I did it myself: with just four screws, the Soundboard was secured to the wall. The sound is incomparable and ﬁlls the entire room, covering the entire spectrum from treble to bass notes. Complex sounds are extremely accurate and detailed.

Caring for your musical instrument The membrane of this speaker has been crafted from over 350-year resonance spruce using lutherie techniques. It is glued and varnished with varnishes that do not perturb the vibration. It is important to care for it like a musical instrument - which means it must not be installed near a source of heat, i.e.

The Soundboard generates an omnidirectional wave. Listeners can be near, far or even in another open space, and they can perceive the music on the same level of quality. The Soundboard is crafted in the tradition of musical instruments that actually play music for us. The impression is that of a concert, with a powerful presence, precision and a well-rounded sound.
Page 18 Where is the resonance chamber? One can in fact see the all piece as a resonance chamber, and the Soundboard plays the role of a vibrating membrane. Despite what one reads on the topic of resonance chambers which are said to amplify sounds, they in fact mostly serve to enable listeners to hear all the frequencies emitted by the soundboard by reducing the acoustic short-circuit inherent to the moment when a membrane begins to vibrate.
