Overview
Product Description
The Siren LFO Kit is a two-stage VCO that combines a tone generator with a low-frequency oscillator. What this means is that not only can this kit generate tones, but the pitch and rate of change of those tones can be controlled via the four potentiometers. The output of this synth can be selected between a triangle and square wave, and the LFO shape can also be changed to either square or triangular. With a push-pull output stage and small 1W 8-ohm speaker, this little kit can provide hours of synthesiser fun while also providing plenty of educational resources.

Applications
- The Siren LFO Kit is an excellent choice for those looking to create their own instruments, as the four potentiometers allow for full manipulation of the output tone as well as the LFO modulation. This also makes the Siren LFO great for use as a siren for RC emergency vehicles, video game sound effects, and dioramas. Additionally, as the kit teaches about LFOs, VCOs, and audio push-pull amplifiers, this kit is also ideal for those learning about electronics, and the numerous components in this kit make it an excellent weekend soldering project.
- Education and training – Useful for teaching low-frequency oscillators, voltage-controlled oscillation and frequency modulation, while providing practical experience with through-hole soldering, component identification and PCB assembly.
- Project integration – Suitable for projects such as Emergency-Vehicle Sound Effect, Experimental Synth Voice, Game and Diorama Sound Generator, and other designs where the following function is useful: Two-stage siren synthesiser combining a tone oscillator, low-frequency modulation and onboard audio output
