201 - Average and Peak Responding Limiter

THIS PRODUCT IS NO LONGER IN PRODUCTION

The Inovonics 201 is a dual-function unit which incorporates both fast-acting peak limiting and average-responding automaqtic gain control functions.

Features


  • Fast Peak Limiting with accurate PEAK CEILING attenuator and variable ATTACK and RELEASE timing.

  • Independent avarage-responding limiter with choice of Averaging or Quasi-VU response characteristics.

  • Unique "Increasing-Ratio" Compression is a continuously variable function of the input level.

  • Extremely smooth operation and low distortion afforded by exclusive open-loop gain control and ripple-cancelling circuitry.
