True Phantom® Power Supply Minimizes Condenser Microphone Distortion

PREMA IC PR2301

TruePhantom^® is a high impedance phantom power supply for condenser microphones with a servo-regulated output voltage of 48V. This decreases the load for your microphone considerably.
Compared with standard phantom supply circuits, TruePhantom® reduces distortion from a condenser microphone output by between 3.6 dB and 14 dB, minimizing especially the third and fifth harmonic. It complies with standard IEC 61938, P48.
The PR2301 integrates the required circuits in one IC, making it easy to replace standard phantom by TruePhantom^® and enhancing the quality of your mixing console.

Applications

• mixing consoles
• microphone preamplifiers
• standalone digital recorders
