Synthesizer Printed Circuit Boards
TH-201 "Mankato" Voltage-Controlled Filter / Oscillator / Slew Limiter
TH-201/4 Mankato (rendering).
Designed by well known synth DIY guru Thomas Henry, the TH-201 is a low-pass VCF with some unusual operating modes. Magic Smoke will be producing printed circuit boards (PCBs) which can provide up to eight outputs. With the Resonance control turned all the way up, these filters will self-oscillate, operating as multi-phase LFOs or VCOs.
Both DC-coupled and AC-coupled inputs are available. The DC-coupled inputs allow the TH-201 to operate as a voltage-controlled lag processor (slew limiter). All outputs are buffered and have standard 1k impedance.
The Mankato covers a very wide frequency range: from around 0.011Hz (90 seconds per cycle) to 22kHz without range switches. Changing the timing capacitors can provide extended low frequency operation. You can certainly build your Mankato with a range switch, if that's your preference. Isn't DIY great?!
The PCB is available for do-it-yourselfers. It is not difficult to build compared to other synthesizer modules, but Magic Smoke does not recommend this for your first DIY experience.
