Here are some interesting videos related to PA and sound reinforcement systems. Wikipedia defines that a public address system (PA system) is an electronic system comprising microphones, amplifiers, loudspeakers, and related equipment. It increases the apparent volume (loudness) of a human voice, musical instrument, or other acoustic sound source or recorded sound or music. The →

https://www.edn.com/electronics-blogs/si-pi-masterclass/4461028/Make-simple-fixtures-from-SMA-connectors For testing SMD components you need some test fixture. A fixed-geometry fixture produces consistent and repeatable results. This article tells how you can easily make fixed-geometry fixtures out of PCB-mounted SMA connectors. You can build a fixture to measure bypass capacitors using SMA-female edge-mount connectors. The narrow-base connectors (5 mm grid) and are best →
