The Lollipop is a studio grade dual-mode analog mono compressor designed specifically for Eurorack. Two different compression modes – FET and Vactrol – give two different flavours of compression. Choose the Vactrol mode for a crystal clear sound, or choose the FET for dirt: try both, suck it and see!

Lollipop features a peak detecting envelope detector, variable attack / release / ratio / threshold, dedicated side-chain, dry/wet control and LED meter. The module is designed to work on a Eurorack signal level of around 10Vpp. As this signal level would not normally allow for deep compression within Eurorack power supplies, the ratio is over compensated to allow for ratio ‘over infinity’.

Lollipop MK.2 adds:
  • Threshold CV input replaced by envelope out
  • Threshold attenuator replaced by uni/bipolar switch for controlling sidechain triggering
  • Output gain is now pre dry/wet crossfader
  • Ratio pot is logarithmic taper
  • Maximum release times have been increased
  • Offset calibration no longer necessary

Lollipop Mk2 – Build Document | Calibration guide


  • Max Attenuation: ~33dB
  • Ratio:  1:1 –   ‘over infinity’
  • LED meter: ~3Db PER led
  • In gain: from -inf to +13.5dB
  • Attack: 2mS –  300mS
  • Release: 30mS – 450mS
  • Width: 12HP
  • Depth: 25mm

Set Up

To get started, set the module controls as follows: threshold to minimum (far right), input gain, attack and release all to 0 – (far left).

Set the output gain to the small 0 marker, the dry/wet to far right (all wet) and the ratio to far right (full).

Make sure your signal is connected and turn the input gain up until the first led lights. This means your input signal is around 10Vpp, the signal level that will give best results.

From here adjust the threshold and ratio to suit your needs. The threshold controls the point at which the unit will start to compress, the ratio controls the amount of gain reduction after that point is reached.

If you are seeking maximum compression, turn the ratio and threshold all the way up.

When a signal is plugged into the side-chain input, the unit automatically uses it as the trigger source. This input is DC coupled! Square waves and pulse waves may give unpredictable results
