W122 Low-Frequency Oscillator
Our 3340 Low-Frequency Oscillator utilises original CEM3340 (Rev. G) architecture, similarly to our 3340 VCO.
It is a voltage-controlled LFO featuring three simultaneous, buffered 10Vpp (±5V) waveforms including DC-coupled ramp, triangle and pulse outputs.
The pulse output has a controllable PW, along with a PWM CV input (±5V range). The PW can be varied manually between 50% and 100% duty cycle with the PW knob on the front panel. When a PWM CV source is input, the PW is normalled to 50% and the CV level is attenuated using the PW knob.
Other features include a controllable FM input that is also calibrated to 1V/octave when the FM knob is fully-clockwise. So the LFO can also be used as a VCO. A comparator-based reversing type sync input also allows the LFO to be synced to another LFO or VCO etc.
The overall frequency range of approximately 0.05Hz to 4.5kHz (e.g. when using a 1V/octave source). By default, the coarse and fine frequency control knobs provide a frequency range of approximately 0.05Hz to 100Hz (this range can be changed using a trimmer on the PCB).
Features
- Original CEM3340 (Rev. G)-based LFO with a range of modulation options including PWM and an FM input calibrated to 1V/octave when FM knob is fully clockwise.
- Can be used as a VCO.
- Three simultaneous, buffered 10Vpp (±5V) waveforms including DC-coupled ramp, triangle and pulse outputs, with a controllable PW and PWM CV input (±5V).
- Overall frequency range of approximately 0.05Hz to 4.5kHz (e.g. when using a 1V/octave source). By default, the coarse and fine frequency control knobs provide a frequency range of approximately 0.05Hz to 100Hz (this range can be changed using a trimmer on the PCB).
- Comparator-based reversing sync input allowing the LFO to be synced to many different types of sources, such as other LFOs, envelopes, gate signals and so on.
- Ergonomic design.
- Hand-built and tested in the UK.
