Available from 11/30/1999 until 11/30/1999
Featuring 8 discrete, matched-transistor, hybrid mic-preamp circuits, PRE offers a pristine signal path designed specifically for the Pro Tools|HD environment. PRE accepts nearly any input signal, easily accommodating mic, line, and direct instrument (DI) level inputs on all eight channels. Comprehensive remote controllable operation via the Pro Tools software interface or Digidesign control surfaces allows you to place PRE anywhere in the studio and retain the ability to take advantage of its entire rich feature set from where you want to operate. PRE also functions exceptionally as a stand-alone device, making the same high-end sonic quality available for non-Pro Tools applications and all standard MIDI controllers.
Technical specifications
8 high-performance, discrete, matched-transistor hybrid microphone pre-amplification circuits
Support for mic (XLR), direct instrument (DI), and line level inputs (1/4")
Each channel includes a high pass filter, phase reverse, 48V (phantom power), and -18 dB pad
Fully remote-controllable via Pro Tools software and Digidesign control surfaces; allows for the highest fidelity by keeping low-level signals close to the source
Selectable impedance matching for mic, line, or instrument inputs
MIDI IN/OUT/THRU ports for remote operation
All features supported in stand-alone mode, making PRE an ideal analog front end for any recording system
