Page 3: Overview
Overview The Hampshire Electronics Dual LFO is a 100% analogue modulation source in the popular Eurorack format. The LFO features two completely independent low frequency oscillator channels, with each channel outputting three independent waveforms, saw/triangle, square and sine. The duty of all three waves is controllable, enabling many waveshapes to be created. As an example, all waves from downward ramp, through triangle and to upwards ramp can easily be dialled in by using the shape knob for each LFO. -
Page 4: Installation
Installation Power Availability The Dual LFO module draws the following current from your power supply: 32ma @ +12v 30ma @ -12v You should first ensure that your power system has enough power capacity to drive the module before considering installation. If you are in doubt, please consult with your power supply manufacturer. -
Page 5: Using The Dual Lfo Module
The waveform outputs all have the voltage levels of -5v to +5v. Shaping the Waveforms The SHAPE knob can be used to shape the waveforms output from the Dual LFO module. Turning the SHAPE knob will affect all three outputs for the relevant LFO (either 1 or 2). - Page 6 For the saw/triangle output, the SHAPE knob will change the shape from a down-slope ramp wave (knob fully left), through a triangle (knob centred) to an up-slope ramp wave (knob fully right). Any variation of these shapes can be achieved by turning the knob appropriately.

Page 7: Trimming The Dual Lfo Module
Trimming the Dual LFO Module The Dual LFO module has a trim pot on the back, which serve to adjust the sine wave shaping circuit. Care must be taken when adjusting the trims pots and it is highly recommended that a good quality oscilloscope is used when making any adjustments.
