Learn how to match passive speakers and amplifiers using impedance, continuous/program power, headroom, DSP crossovers and limiters — without cooking drivers or forcing amps into protect.
Soundcheck is not just “making sure the microphones work.” It verifies gain structure, feedback margin, monitor mixes, room coverage, RF, playback and show cues before the audience arrives.
Line arrays are not automatically better than point-source speakers. Learn how coverage, throw distance, directivity, array length, room geometry and deployment determine the right system.
Speaker placement changes with room shape. Learn how to plan PA coverage for long halls, wide rooms, churches, low ceilings, reflective spaces and outdoor events before the gear arrives.
Choosing a PA system is not about matching watts to crowd size. Learn how SPL, speaker sensitivity, coverage, subs, room acoustics and headroom determine the right system for your venue.
A bridged amplifier driven into a load it was never rated for, a compression driver cooked by a clipping amp, gear bought on a wattage figure the mains couldn't deliver. Almost all of it comes down to impedance — here's the guide we wish every customer had read first.
Watts is the number printed biggest on the box, and it's the least useful one when you're sizing a PA for a hall. Here's the method we actually use — throw, coverage angle and headroom — with the sums you can do on a phone calculator.
Every guide here is written by the technicians, installers and sales staff who work on this equipment daily — in our Blackheath workshop and on site across South Africa. Prices are local, the failure modes are ones we have actually repaired, and where a product is named it is because we have had it on the bench.
If a guide is out of date, tell us and we will fix it. If you want advice on your specific room, budget or crowd, come and talk to us — that part is free.
