Accusound offers alternative methods of re-inforcing the acoustic sound of guitars or similar instruments with round sound holes such as cittern
The device is attached to the sound-board by
means of low-tack double-sided tape. Where
especially sensitive surfaces are involved a
special non-invasive technique is available.
1.
The Accusound contact microphone,
photo 1, provides a
method of picking up the many vibrational nodes
distributed throughout an instrument's
sound-board. Since the pattern of these
nodes varies according to the note that is
being played, a ‘hot spot’ type pick up will
select less of these nodes.
All Accusound contact microphone are available
in two electrical configurations:
A FET version and phantom power adaptor is
supplied to connect to a standard mixing desk or
balanced microphone input of a PA system. If
phantom power is not available then a battery
phantom power adaptor can be supplied, this can
also be used into a back-line or guitar
amplifier.
A non-FET version can be supplied if you wish to
connect to a back-line or guitar type amplifier
but do not wish to use a phantom power adaptor.
2. Perhaps the simplest method of reproducing the acoustic sound of any acoustic instrument is
by using a microphone. To reduce the risk of feedback and
to improve separation between instruments, Accusound has developed a method of mounting a miniature electret capsule in the sound hole directly underneath the strings (photo 2,
3 & 4)
As our ears are not used to hearing
the acoustic sound so close to the sound
hole and strings, some equalisation may be
required to correct the tonal balance of the
output. This can usually be achieved by the
tone controls of the input mixer or a
separate equaliser.
3. The two devices described above
are available as a combined system where
each pickup has it's own volume control but
a single signal is fed to the PA system.
All
Accusound products are available as wireless
systems.
