Frequency Selective / Broadband Peak Limiter

Share on Facebook Share on Twitter

THIS PRODUCT IS NO LONGER IN PRODUCTION.

The Inovonics 210 is a dual purpose gain limiting device for use in broadcast and recording applications requiring independent control of both high frequency program energy and broadband program peaks.

Features


  • Fast Peak Limiter with Variable control of Peak Ceiling, Attack and Release.

  • Separate Frequency Selective Limiter with plug-in inserts to compliment a variety of high frequency overload characteristics.

  • Very Low Distortion even at low frequencies, assured by unique ripple-cancelling circuits.

  • Instant Display of limiting action by peak-responding indicators. Optional remote-mounting meter may be located at console.
