A special selected noise diode generates the white noise, and a vacuum-tube pentode in order to gate the noise on and off.
A built-in envelope generator allows adjustment of the attack and decay time. Long attack times will require triggering with a long positive pulse, while “typical” cymbal sounds can be made with a short trigger pulse.
A trigger of at least +5 volts is recommended for best performance. A built-in high-cut filter allows adjustment of the noise sound from full-range to a rolloff of about 100 Hz, giving a unique "thunk" tone.
