LP-22  ADR/Foley Processor

The LP-22 is a unique processor designed specifically for foley and dialog work in film and television post production, combining a high quality microphone preamp and full dynamics.

 

 

  • 0 to 75dB gain in 2 stages.
  • Input accepts up to 25dB without clipping.
  • 20dB pad with constant impedance.
  • Phantom power and phase reverse.
  • Common mode inductive filter protects against RF interference
  • 7 LED bargraph provides PPM metering of mic output stage.
  • Overload indicator at +18dBu which.is approximately 9dB before clip (user adjustable)
  • Low-pass and High-pass filters with overlapping frequencies cover entire audio range.
  • Insert .point with bypass for external device insertion and independent use of mic preamp and dynamics sections in a mixing console via patch bay insertion.
  • Dynamics section combines Compression, Limiting, De-essing, Expanding and a Noise Gate with independent side chain.
  • Fully variable Threshold, Range and Release times.
  • Threshold adjustable from -20dB to +10dB.
  • De-esser switch inserts a custom slope high pass filter in compressor side chain.
  • De-esser frequency control sweeps the band from 2kHz to 18kHz.
  • VCA controlled side chain provides transparent fades to silence.
  • Program dependent Attack time (unless "fast attack" switch is engaged).
  • Bargraph meter displays gain reduction from 0dB to -20dB.
