Key Features:

  • Electronically balanced ultra high bandwidth input with -5dB to +75dB gain control & Pad switch
  • Continuously Variable input impedance control (1.2kOhm to 10kOhm) can accommodate signals from instruments or be adjusted to suit a wide range of microphones
  • Phase Reverse & Phantom Power
  • Dedicated Additional XLR Line Input
  • Front panel instrument input with ground lift switch
  • Independently switched 12dB/Octave HF (Low-Pass) Filter
  • Independently switched 18dB/Octave LF (High-Pass) Filter
  • Independent routing to L & R Record bus
