Multiples and mixing

More than a multiple

Links provides 3 utility functions focused on signal distribution and mixing.

4HP
25mm
+12V:15mA
-12V:15mA

Three essential functions

  • The 1:3 section is a buffered multiple, allowing a note CV to be distributed to up to 3 VCOs without voltage drop.
  • The 2:2 section is a 2-input summer with unity gains (also known as a precision adder). The sum of the two input channels is distributed to 2 outputs.
  • The 3:1 section is a 3-input mixer, with a gain of 13 per channel (also known as an averager). It is particularly suitable for rapidly mixing audio sources such as oscillators, for which a unity gain mixer would have caused clipping.

Specifications

  • Input impedance: 1M for the buffered multiple, 100k for the mixers.
  • Buffered multiple with low offset error.
  • 0.1% resistors, allowing the 2:2 section to work as a precision adder.
  • All inputs DC-coupled.
  • Audio-rate signals accepted.
