About the Synth Geekery Show

Synth Geekery is a weekly podcast/live stream (YouTube) show about everything synthesizers, drum machines, samplers, sequencers, eurorack and music technology. We take the “one of the masses” viewpoint, where we are also users of gear just like you (read: we’re not influenced by commercial product placement).

The show relies on the generous contributions of the synth community. You can contribute in many ways including supporting us via our YouTube Channel Membership or Patreon. There is also a Merch Store: https://ranzee-shop.fourthwall.com/. We also have regular and special video guests: if you would like to take part in future shows – please contact me via email on the about page here.

Feedback Modules 4XXX Compressor

The 4XXX Compressor is a Eurorack module developed by Feedback Modules in collaboration with CMS-LAB. Inspired by the renowned British stereo bus compressor, often referred to as the “glue compressor,” this module is designed to cohesively bind mix elements, delivering a polished, professional sound. It’s particularly effective on drums, adding punch and cohesion to your tracks.​

Feature List:

• Stereo Input Level Control: Adjusts the input level to prevent clipping, indicated by a red LED.
• Stereo Makeup Gain Control: Compensates for gain reduction post-compression; includes CV control for dynamic modulation.
• Compression Threshold: Sets the level at which compression begins; lower thresholds result in more compression.
• Attack Time: Determines how quickly compression engages after the threshold is exceeded.
• Release Time: Controls how quickly compression stops after the signal falls below the threshold; includes an AUTO RELEASE setting that adapts to signal content.
• Compression Ratio: Defines the intensity of compression above the threshold; options range from gentle to aggressive compression.
• Gain Reduction Meter: A four-LED meter provides visual feedback on the amount of gain reduction occurring.
• CV Control: Allows external control voltage to modulate the makeup gain, enabling dynamic changes over time.
• Specs:
  • Power Consumption: 85 mA at +12V, 75 mA at -12V.​
  • Form Factor: 12 HP width, 35 mm depth.
