Capture pristine, high-quality sound with PRE. Featuring eight discrete, matched-transistor, hybrid mic preamp circuits, PRE provides a transparent signal path, and easily accommodates your mic, line, and direct instrument (DI) level inputs on all eight channels. Plus, you can place PRE anywhere in your studio, thanks to its remote-controllable operation, which you can access through Pro Tools HD software or an Avid control surface. And because PRE also functions as a standalone device, you can get the same sonic quality when working with any application and outboard sound module.
Features
Whether you’re using PRE with a Pro Tools|HD system or as a standalone mic preamp, you’ll get great sound quality with all mic, line, and direct input signals you send through it.
- 8 high-performance, 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 using Pro Tools HD software or an Avid control surface; 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 standalone mode, making PRE an ideal analog front end for any recording system
