This set of PCBs adds an EQ section of the famous vintage class-A mic preamp to your existing 1290 module.
Here are the key features of our 73EQ PCBs:
- Point-to-point board connections wiring where possible - as in the vintage modules.
- Boards accept either Grayhill or Lorlin switches.
These PCBs are intended to be used in our 4-channel frame system and take up one slot space. We suggest installing no more than two modules if using internal PSU.
Important! This module can't work without the 1290 mic preamplifier module.
