Audio

This section covers audio test equipment and installation tools used by AV installers, studio techs, live sound engineers, and electronics hobbyists. Choose from instruments that help you measure, tune, wire, and troubleshoot everything from home theaters to broadcast racks. The right tools speed up setup, raise sound quality, and reduce costly callbacks.

Popular audio tools include:
- Audio analyzers and real‑time spectrum analyzers for frequency response, SPL, and THD+N
- Signal and tone generators for sweep, pink/white noise, and reference levels
- SPL and dB meters with weighting filters and data logging
- Oscilloscopes and USB interfaces for waveform and noise diagnostics
- Cable testers for XLR, TRS, SpeakON, RCA, and digital formats
- Impedance meters and dummy loads for speakers and amplifiers
- Wired and wireless network audio testers for Dante, AES67, and AVB streams
- RF scanners and antenna analyzers for wireless microphones and IEMs
- Calibrated measurement microphones and acoustic calibrators
- Crimpers, strippers, soldering stations, and heat tools for reliable terminations

When selecting audio test equipment, match the frequency range to 20 Hz–20 kHz or wider, check measurement accuracy, and look for balanced/unbalanced I/O as needed. Consider features like phantom power, loopback testing, FFT/RTA modes, latency analysis, and PC/mobile software. For live sound, seek rugged housings, daylight‑readable screens, and long battery life. For studios and install work, prioritize repeatable calibration, file export (CSV, WAV), and integration with DAWs or control systems.

Good practices keep projects on schedule. Label and verify every cable, keep adapters in one case, and run a quick line check with a tone generator before doors open. Calibrate SPL meters annually, store microphones with their correction files, and verify firmware for networked gear. With the right audio tools, you’ll diagnose faster, tune systems with confidence, and deliver clear, reliable sound. Find trusted brands, compare specs, and choose tools that fit your workflow today.
