KEY FACTS The QSC K12.2 and Yamaha DXR12 are two of the most respected active PA speakers in the $700 to $900 price bracket. The QSC K12.2 is louder and has more onboard DSP flexibility. The Yamaha DXR12 is lighter and has a more musical, refined sound character. Both are professional-grade speakers suitable for small to…
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 FACTS EQ is the most powerful and the most abused tool on a mixing console.Most engineers add too much EQ. The best results usually come from cutting problem frequencies rather than boosting pleasant ones.Every common live sound problem, including boominess, harshness, muddy mids, and thin vocals, has a specific EQ solution.This guide gives you…
KEY FACTS Passive PA speakers require a separate power amplifier, which gives you more control over system configuration and often better long-term value at scale.The best passive speakers under $500 per cabinet come from Yamaha, Electro-Voice, QSC, and RCF.Power handling, sensitivity, and coverage pattern matter more than peak SPL ratings when choosing passive speakers.This guide…
KEY FACTS A line array delivers more consistent volume across a large coverage area than conventional point-source speakers by controlling vertical dispersion. Proper array curvature (splay angle) is the most critical setup variable. Too little splay creates hot spots. Too much creates coverage gaps. Outdoor line arrays require more subwoofer support than indoor systems because…
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 Lavalier microphones (lapel mics) are the most discreet and natural-sounding option for speakers, presenters, and preachers. The most important factors in choosing a lavalier are consistent level as the speaker moves, feedback rejection, and ease of concealment. Good lavalier placement is as important as the microphone itself. A badly placed high-quality lavalier will…
KEY FACTS A quality wireless microphone system under $300 is now genuinely achievable from brands like Sennheiser, Shure, and Rode. For churches and small events, the most important factors are reliability, battery life, and range rather than sound quality alone. This price bracket is ideal for a single presenter or vocalist but is not designed for…
KEY FACTSMicrophone feedback is caused by a loop where the microphone picks up its own amplified signal from the speakers.Feedback can be prevented through correct microphone placement, speaker positioning, EQ notching, and gain structure.Ringing out a system before the event is the single most effective step you can take to prevent feedback at a show.When…
