In live sound and house of worship audio, getting the relationship between your power amplifier and your passive loudspeakers wrong leads to two expensive outcomes: a system that constantly clips and distorts, or blown drivers. While many audio forums offer vague advice, calculating the required power requires balancing continuous power ratings, impedance loads, and dynamic…
KEY FACTS: Class AB amplifiers have been the live sound standard for decades. Class D has largely overtaken them for touring and installation work in recent years. Class D amplifiers are lighter, run cooler, and are more energy efficient. Class AB amplifiers have a longer track record, and some engineers prefer their behaviour under load. For…
KEY FACTSBridging combines both channels of a stereo amplifier into a single more powerful mono output.Bridged mode roughly doubles the available power compared to a single channel at the same impedance.The most important rule of bridging: the minimum speaker impedance doubles. An amp rated for 4 ohms per channel can only drive 8 ohms when…
KEY FACTSThe Crown XLi 3500 and QSC GX5 are two of the most popular budget power amplifiers used in live sound worldwide.The Crown XLi 3500 offers more raw wattage for the price. The QSC GX5 offers better build quality and more reliable long-term performance.Both are suitable for mid-size live events, churches, and small to medium…
KEY FACTS• Churches require 5 to 10 watts of amplifier power per seat as a starting baseline.• Room acoustics, ceiling height, and worship style affect the real-world number significantly.• A church of 200 seats typically needs 1,000 to 2,000 watts of amplifier power for comfortable, clear speech and music.• Bigger is always safer — headroom…
KEY FACTS• Power amplifiers cut out due to overheating, impedance mismatch, clipping, gain issues, or faulty cabling.• Thermal protection is the most common culprit and almost always a symptom of a deeper problem.• Most cut-out issues can be diagnosed and fixed without replacing the amplifier.• This guide walks you through every cause systematically, from the…
