PRE |
Remote-controllable, world-class, eight-channel mic preamp
|
DigiDesign |
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
