RMP2 Ribbon Mic Preamp Features:
- Two transparent channels
- Optimized for Ribbon Mics - No transformers or capacitors in the signal path, and no phantom power
- Entirely balanced circuit from input to output
- Discrete front end, THAT 320 precision quad matched bipolar junction transistor arrays (each balanced circuit has 5 paralleled)
- Dual servo design to reduce DC offsets and common mode error
- Balanced signal path uses 0.1% precision metal film resistors and metal film resistors are used throughout
- WIMA film capacitors for servos, and COG ceramic for PS decoupling
- Elma type A4 24-position precision high-quality gain selector switches
- Two layer PCB with silk screen, solder mask and large low impedance ground plane
- External universal AC input power supply (90-264 VAC).
- Vinyl clad steel cover with aluminum base and end panels
- Compact size for portability or optional 1u rack mount adapter
