- Whether you’re using PRE with a Pro Tools|HD family 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
