About: DBX 286s Mic Pre-Amp Processor

Microphone Processor Single channel studio quality mic preamp plus five dynamics processors which offers: internal power supply. +48V phantom power, and frequency controllable de‐esser, as well as a premium pre‐amp section and expanded metering 2‐knob compression, spectral enhancer and an expander/gate make the 286A vital in any environment.

  • Studio quality Mic Preamp/Channel Strip Processor
  • Classic dbx Compression puts great sound within easy reach
  • Frequency tunable De-Esser reduces sibilance and high frequency distortion
  • Enhancer increases the detail and definition of the high and low frequencies
  • Program adaptive Expander/Gate
  • Insert jack allows you to add an external processor
  • Full compliment of meters and status LEDs
  • +48V Phantom Power
  • Precision detented controls
