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. 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. 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!
