  • Stable operation
  • Electrostatically shielded
  • Operation under wide voltage range

Please note: Only install the 1122 opamp in units that were known to be working, such as older API modules. You may permanently damage the op-amp if the pins you’re plugging them have not been tested.

The 1122 is the same size as older API 2520 opamps and were originally designed to take their place for use in eq modules or consoles of that era. Newer 2520’s are slightly smaller and in some places the 1122 will not fit.
