Intellijel Buff Mult 1U

Dual 1×4 buffered mult — 1×8 when normalled. Pitch-accurate CV distribution.

14 HP Eurorack module

Buff Mult 1U is a 14HP Intellijel 1U-format dual buffered multiple. Each section is a 1×4 buffered mult: a single audio or CV input is electronically copied to four output jacks via a unity-gain buffer, isolating the source from the loads. The top input is normalled to the bottom input, so when the bottom is unpatched the module behaves as a single 1×8 buffered mult. Buffering preserves voltage accuracy critical for 1V/Oct pitch CV distribution and protects the source from output shorts.

Features

  • Dual 1×4 buffered multiple (acts as 1×8 when bottom input is unpatched)
  • Active op-amp buffering preserves voltage accuracy for 1V/Oct pitch CV
  • Top input normalled to bottom input for single 1×8 mode
  • Outputs are electrically isolated from input and from each other
  • Output shorts and faults cannot pass back to the source module
  • Works equally well for audio and CV
  • 14 HP in Intellijel 1U tile format
  • Skiff-friendly 29mm depth
  • Low power draw (4mA per rail)
  • No knobs or switches — pure utility

Controls & Jacks (10)

  • Input 1— Top section input. Audio or CV signal that gets buffered and copied to the four top outputs. Normalled to Input 2 — when Input 2 is unpatche
  • Output 1A— Buffered copy of Input 1.
  • Output 1B— Buffered copy of Input 1.
  • Output 1C— Buffered copy of Input 1.
  • Output 1D— Buffered copy of Input 1.
  • Input 2— Bottom section input. Audio or CV signal that gets buffered and copied to the four bottom outputs. Normalled from Input 1 — patching here br
  • Output 2A— Buffered copy of Input 2 (or Input 1 if Input 2 is unpatched).
  • Output 2B— Buffered copy of Input 2 (or Input 1 if Input 2 is unpatched).
  • Output 2C— Buffered copy of Input 2 (or Input 1 if Input 2 is unpatched).
  • Output 2D— Buffered copy of Input 2 (or Input 1 if Input 2 is unpatched).

How-To Guides

  • Distribute pitch CV to multiple oscillators
  • Use as a single 1×8 buffered mult (via normal)
  • Distribute two independent signals (1×4 + 1×4)
  • Use as a protective buffer between modules
  • Pre-buffer an audio signal before splitting to effects sends
