| Featuring eight discrete, matched-transistor, hybrid mic-preamp
circuits, PRE offers a transparent 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 TDM 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.
Features
- 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
