WE
ARE OUT OF STOCK OF LV4 THEREMINS
BUT
YOU CAN STILL PLACE ORDERS,
MORE
STOCK EXPECTED 19th March.
Create music from
the ether; eerie sci-fi, psychedelic, ambient, rock, classical etc..
by moving one hand towards or away from the pitch antenna and control
the volume by moving the other hand up and down over the volume loop
antenna.
Believed to be the earliest electronic musical instrument developed
in the 1920s, the Theremin - named after its inventor Leon Theremin,
is unique in that it is played without being touched, instead it's by
the players' proximity to the pitch and volume antennas.
The Lostvolts.com LV-4 theremin features a full width case and it's
electronics are 100% analogue. It has a 6 octave range.
Along with the usual controls for Pitch Antenna Tuning, Volume Antenna
Response and Master Volume, the LV-4 has two extra controls - Waveshape
and Filter, which subtly change the timbre of the tone from pure
to woodwind through to string-like.
Compact and easy to transport, the LV-4 theremin is supplied with a
telescopic pitch antenna and a loop volume antenna along with a quality
power adaptor (9 to 12 volt dc, 2.1mm centre positive). There's also
a vintage germanium diode in the detector stage.
There is no internal
speaker, so it must be used with an amplifier.
Not just to amplify but also for the theremin to work properly. Instrument
amplifiers for electric guitars, keyboards etc. work well. USB audio interfaces
to "desktop" computers such as Behringer's UMC range should
work. Hi-fi, active computer speakers can work but may need an appropriate
lead. The theremin has a MONO 1/4" (6.35mm) jack output for a standard
electric guitar lead. It won't power earphones, you will need an amplifier.
For correct operation the amplifier should have a good electrical earth.
An amplifier that doesn't have a mains plug with 3 metal pins (or if it's
battery powered) probably won't be connected to earth. This can result
in weird modulated sounds, reduced pitch and volume range and may make
tuning difficult. Again, USB audio interfaces to "desktop" computers
should work as they are earthed through their IEC mains cables. Laptops
and tablets which have a plastic earth pin on their plugs may not work
well.
The science bit: This is a transistorised, analogue Theremin, using the
heterodyning principle. It generates a tone by obtaining the difference
audio frequency from two radio frequency oscillators. It has coils in
it's oscillators that generate the classic Theremin tone through their
reactions with each other.
Because there are no keys or frets etc., the Theremin isn't the easiest
instrument to play, but it has to be the most fun!
