Pueblo Audio JR2/2-ADR-LIM

This variation of our JR2/2 mic preamp has been tailored for the needs of ADR stages.   First, we replace the standard rotary gain switches with high quality potentiometers which move fluidly and are comfortable to the hand.  The pot's gain range fits perfectly for riding vocal performances.  Pot action does not introduce scrapping or other wiper noise while gain ramps smoothly without sudden, wild jumps at the top of its travel.  Shooting extremely quiet talent can be a challenge so +15dB Gain Boost Switches bring total maximum gain to +75dB.  This allows the capture of the faintest breathes and sighs with vanishingly low noise and great intelligibility.  Integrated 35Hz high pass filters help control low frequency room tones without reaching up into the vocal range.  The combo of this HPF with the JR2/2's low self-noise and outstanding EMI/EMF rejection mitigates structural and telecom based intrusions.  Mixers have report very successful matching with production sound without fuss or extra work.  The JR2/2-ADR's outstanding specifications are the same as the JR2/2​​ listed above. 

In addition to these core features we will also offer a Peak Limiter option.  For practical ADR applications a "set it and forget it" approach was taken.  The limiter's peak ceiling is adjusted just below the recorder's clipping level.  When the signal reaches that ceiling it is held there with low distortion, preventing overload of the recorder's ADC.  What is special about our limiter option is that it does not introduce additional circuitry to the signal path.  Instead, the preamp's existing gain structure is controlled without loss.  This minimal signal path preserves more of the talent's nuances for heightened drama.
