The Hampshire Electronics 3340 VCA is a 100% analogue voltage controller oscillator in the popular Eurorack format.
The oscillator utilises the famous 3340 analogue oscillator integrated circuit popularised by a range of classic analogue synthesizers from the 1980s onwards. The 3340 has recently re-entered production, enabling a new generation of synth enthusiasts to enjoy its stability and sound quality.
The key details of the oscillator are:
- 14HP Wide Eurorack module with thin profile (20mm deep from faceplate)
- Controls designed and laid-out with performance in mind
- 100% analogue circuitry
- Excellent stability and temperature compensation from the 3340 analogue oscillator IC
- 2 x 1v per octave inputs with excellent tracking across all octaves
- Coarse and fine-tuning knobs with a tuning defeat switch
- Output frequencies of all wave shapes from less than 1Hz to over 40kHz
- Standard 16-pin Eurorack power connector with clear markings to ensure correct connection orientation
- Simultaneous ramp, square, triangle and sine wave outputs
- 2 x exponential FM inputs accepting the standard +5v to -5v levels, each featuring an attenuator
- 1 x linear FM input accepting standard +5v to -5v levels, featuring an attenuator
- Pulse width control of the square wave output
- Pulse width modulation input for the square wave output, accepting the standard +5v to -5v levels and featuring an attenuator
- Classic 3340 hard and soft sync inputs accepting a 0v to 5v square wave input
- Diode protected power input
- 23ma @ +12v
- 24ma @ -12v
