Features & Benefits
- Speakers and power amplifiers do the heavy lifting in amplified music.
- Power amps take low-level output and up the voltage significantly to drive PA speakers and stage monitors.
- Standalone power amps make sense if you want to grow your sound system over time.
- Replacing the entire unit of a powered speaker system can be costly.
- Headroom is important to prevent distortion when dealing with wide variations in dynamic range.
