2hp Buff

2HP active 2:6 buffered multiple — split pitch or audio without sag.

2 HP Eurorack module

The 2hp Buff is a fully-active buffered multiple in 2HP. The panel splits into two channels of four jacks each: Input 1 with three outputs, and Input 2 with three outputs. Each output is fed by a unity-gain op-amp buffer, preserving voltage and tone when distributing one source to several destinations. Input 1 is normalled to the second channel, so with a single cable patched it acts as a 1-to-6 mult; patch Input 2 and the lower bank becomes its own independent 1-to-3 mult.

Features

  • Active 2:6 buffered multiple
  • Unity-gain op-amp buffers on every output
  • 1-to-6 mode when Input 2 is unpatched (Input 1 normals across)
  • Two independent 1-to-3 mults when both inputs are patched
  • Preserves V/Oct accuracy when stacking oscillators
  • Maintains audio integrity across multiple effect sends
  • No noticeable voltage sag versus a passive stackcable mult
  • 8 TS 3.5mm jacks (2 inputs, 6 outputs)
  • Compact 2HP form factor
  • 10mm depth — fits the shallowest skiffs
  • Available in silver or black panels
  • No knobs, switches, or LEDs — pure utility

Controls & Jacks (8)

  • Input 1— Signal input for the first channel. Normalled to Input 2 internally — when no cable is patched into Input 2, Input 1 is also copied to Outpu
  • Output 1— Buffered copy of Input 1. Audio or CV passes through with a unity-gain op-amp stage so the source impedance to downstream destinations stays
  • Output 2— Second buffered copy of Input 1, identical to Output 1. Useful for splitting a V/Oct pitch CV to two oscillators without the voltage sag of
  • Output 3— Third buffered copy of Input 1. Together with Outputs 1 and 2 this provides three precision copies of the upper-channel input.
  • Input 2— Signal input for the second channel — feeds Outputs 4, 5, and 6 only. Patching a cable here breaks the internal normal from Input 1 so the l
  • Output 4— Buffered copy of whatever is currently feeding Channel 2 — Input 2 if patched, otherwise Input 1 via the internal normal.
  • Output 5— Second buffered copy of the Channel 2 source. Identical behavior to Output 4; tracks the Input 1 normal when Input 2 is unpatched.
  • Output 6— Third buffered copy of the Channel 2 source. Bottom-most jack on the panel.

How-To Guides

  • Tune three oscillators from one pitch CV
  • Use as a 1-to-6 mult (default)
  • Two independent 1-to-3 mults
  • Send one audio source to multiple effects
  • Distribute a master clock without timing skew
