The pedal has a direct level control knob for exact tonal shaping and separate controls for octave 1 (OCT1) and octave 2 (OCT 2).
Specifications: • 3 Controls: Octave 1 Level, Octave 2 Level and Direct Level • Connectors: Input, Output, AC Adaptor • Residual noise: -100dBm (IHF-A) • Maximum input level: -5dBm • Maximum output level: 0dBm • Input impedance: 1MΩ (FET input) • Output load impedance: > 10kΩ • Minimum operating input level: -60dBm al 250Hz • AC Adaptor: ACA series (black label) or PSA series (silver label) • Current Draw: 4mA (DC 9V) • Weight: 400g (including battery)
IC1/IC2/IC3/IC7/IC6 buffer, boost and "square up" the incoming signal then divide the fundamental of the incoming frequency by 2 and by 4.
IC5b (pins 5/6/7) mixes the incoming signal and the 1/2 frequency square wave from the flip-flops. This signal is then fed to IC4b (pins 5/6/7) which is a low pass filter/buffer. IC4b cleans up the signal and feeds it out through VR1 as OCT1.
IC5a (pins 1/2/3) mixes the signal coming out of OCT1 and the 1/4 frequency square wave from the flip-flops. This signal is then fed to IC4a (pins 1/2/3) which is a low pass filter/buffer. IC4a cleans up the signal and feeds it out through VR2 as OCT2.
