DESCRIPTION

This variation of our standard JR2/2 model has the exact same performance and specifications then adds High Pass Filters and +15dB Gain Boost Switches.
2 Channels of our Precision Phantom Networks
  • High-current design delivers stiff, zero-sag mic powering (mic performance is king, regardless of preamp used!)
  • Clean +50V regulation for each channel provides independent mic operation (like having individual tube-mic supplies).
  • Precision-Matched components for maximum balance, noise rejection & signal yield.
  • Phantom circuits are isolated from preamp channels offering unique flexibility & minimalist signal paths.
  • HPF Switch transforms the phantom network into a minimum phase, 35Hz high pass filter without introducing extra circuitry (custom freq. available upon request).
2 Channels of our DC-Coupled Microphone Preamps
  • Impeccable Fidelity, Resolution & Spacial Imaging.
  • Shockingly low apparent noise, even with ribbons.
  • Precision Rotary Gain Switch: +7.5dB to +65dB.  24steps, 2.5dB/step.  Tight ±0.1dB matching between every channel.
  • Gain Boost Switch adds 15dB to Main Output for a total max of +80dB!
  • Overload-proof headroom & low selectable gain eliminates need for pads.
  • Main Output:  Balanced XLR drives any length of cable, punching through difficult loads like a jack-hammer through concrete.
  • Auxiliary Output:  Separately buffered, quasi-balanced 1/4" TRS jack provides bonus functions as described below:
