The filter that defined a generation of classic polysynths — now in 8HP Eurorack format. Tiptop Audio's Z2040 is a discrete 4-pole 24dB/oct low pass filter built around the same circuit topology as the SSM2040 chip from the Prophet 5 Rev 2. Gently used, white panel, excellent condition, fully functional.

What it is:

The Z2040 is Tiptop Audio's redesign of the most famous analog filter from the polysynths of the 80s. Its heart is a discrete design 4-pole low pass filter with a core similar to the SSM2040 filter chip used in the Prophet 5 Rev 2 synthesizer, and its brother the SSM2044, used in the famous early EMU samplers and PPG synthesizers. 

When set with Resonance feedback fully up, the Z2040 transforms into a pure sine-core VC-Oscillator, great for making snappy percussive elements and whistling sounds. 

Controls:

  • Frequency (cutoff)
  • Resonance with VC-Resonance input
  • Gain — three regions: SSM2040 sweet spot, gain-compensated resonance, soft/hard clipping
  • FM with VC-FM index (modulate the modulation amount)
  • Built-in VCA — configurable pre or post filter

CV/Audio Inputs:

  • FM In, VC-FM, VC-Resonance, 1V/Oct (for self-oscillation pitch tracking)
  • Audio In / Audio Out
  • All modulation inputs accept both CV and audio signals

Specs: 8HP, 20mA +12V / 20mA -12V, 42mm deep

Condition: Gently used. White panel. Excellent cosmetic and functional condition. No rack rash.

Why it sounds different: Most Eurorack filters are based on the Moog ladder or CEM/SSI chips. The Z2040's SSM2040-style OTA core has a distinct character — smoother at low resonance, grittier when pushed into overdrive, with a bass weight that Moog-style filters don't replicate.

Ships carefully packed via UPS with tracking and insurance from Los Angeles, CA. Kept in a temperature controlled, smoke free and pet conscientious studio environment.
