"Magic Smoke is the exclusive licensed source of Thomas Henry's books on do-it-yourself musical electronics as well as the source for exclusive analog synthesizer modules and kits. For starters, we're bringing out Thomas's classic books plus his fantastic new voltage controlled filter."The Mankato!
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 kits for a four output model (TH-201/4) and an eight output model (TH-201/8). 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 TH-201 VCF will be produced as a kit in Euro Rack and Frac Rack panel formats. The PCB will be available separately for those who want to package the TH-201 in other formats.
The Mankato covers a very wide frequency range -- around 0.005Hz (200 seconds/cycle) to beyond 20kHz without range switches. Changing the timing capacitors can provide extended low frequency operation.
TH-201/4
• 12 and 24 dB outputs
• inverted 12 and 24 dB outputs
• 90 degrees of phase difference between each output
• quadrature sine wave oscillator
TH-201/8
• 6, 12, 18, and 24 dB outputs
• inverted 6, 12, 18, and 24 dB outputs
• 45 degrees of phase difference between each output
• 8-phase sine wave oscillator
