  • Single Discrete Input with Thru
  • Gain Select Switch - High/Low
  • Phase Reverse Switch
  • Ground Lift Switch
  • External Power Transformer for a very low Noise Floor
  • Three Band fixed frequency Tone Filter with 12db cut/boost - High/Mid/Low
  • All Metal Chassis
  • Milled Aluminum Knobs
  • Balanced XLR Gold Pin Neutrik Outputs
  • Switchcraft 1/4" Input Jacks
  • Bipolar Electrolytic Capacitors
  • 1% Metal Resistors

APPLICATIONS:

  • Output to Line-In to FOH or Stage Monitors
