Befaco Atte
Quad attenuate, invert, split, and offset any signal
4 HP Eurorack module
ATTE is a quad attenuator/inverter, splitter, and offset generator for Eurorack systems. Each of its four channels can scale incoming audio or CV signals from unity gain down to zero, or invert them, with cascaded inputs allowing a single source to be split and independently scaled across all four outputs. The first channel is normalled to 10V, making it a precision offset generator when no input is patched.
Features
- Four independent attenuator/inverter channels
- Inversion switch per channel selects gain of 0 to 1 or 0 to -1
- Precise zero at leftmost pot position
- Four LEDs indicate output level and polarity (green positive, red negative)
- Cascaded input topology: IN A normalled to IN B, IN B to IN C, IN C to IN D
- Channel A input normalled to 10V for use as offset generator
- Accepts input voltages from -10V to +10V
- Functions as a 1-to-4 signal splitter when inputs are left unpatched
- Available in assembled (25mm depth) and DIY (35mm depth) versions
