Smart Rails Management (SRM)
Smart Rails Management (SRM) dynamically adjusts internal voltage rails based on real-time audio output demands. Powersoft’s SRM significantly reduces energy consumption during lower audio output conditions, improving overall efficiency.
How does Smart Rails Management work?
- Dynamic voltage adjustment — continuously monitors audio signals, adjusting voltage rails to match precise requirements.
- Feedback and thermal management — integrated control systems reduce thermal load, enhancing component lifespan.

Key facts
- Supply rails dynamically track the audio waveform.
- Significantly reduces energy consumption during lower audio output conditions.
- Lower voltages at reduced outputs minimize noise; electromagnetic emissions are reduced.
What are the advantages of SRM?
- Idle power reduction — essential during quiet periods, greatly reducing power usage.
- Enhanced audio clarity — lower voltages at reduced outputs minimize noise, improving audio fidelity.
- Improved EMC — reduces electromagnetic emissions, aiding regulatory compliance.
