Review: Great tool - it has upset many - If you don’t know, this is basically a clone of the original Sound Bullet which was made by an Independant company and has now been kinda knocked off by xvive. That said, it’s pretty well made, a great price and if you weren’t going to afford the real deal this a great option.
Review: Reliable and a Must-Have for Any Audio Tech - I use my Xvive AT-1 cable tester all the time, and it’s been an absolute game-changer in my workflow. It’s quick, accurate, and easy to use—exactly what you need when troubleshooting on the fly. The build feels solid, and it gives me confidence that I’m getting dependable results every time. I’m really glad I purchased it; it’s one of those tools that just makes life easier in live production and saves me from headaches before they start. Highly recommend it to anyone working in audio.

## Features

- Simplify Audio Troubleshooting: The AT-1 audio tester integrates a signal generator, XLR cable tester, phantom power checker, input level meter, and headphone/speaker monitoring into a single compact unit. Designed for live sound engineers and audio professionals, it’s perfect for testing and troubleshooting PA systems, mixers, DI boxes, and effects units.
- Signal Generator: The AT-1 tester produces a 1 kHz sine wave or pink noise, with outputs available via XLR, 6.35 mm (1/4"), or 3.5 mm(1/8") connectors. Output levels are adjustable (-10 dB, -20 dB, -40 dB),making it ideal for frequency response analysis and signal path diagnostics.
- XLR Cable Tester:Easily test XLR cables with automatic pin-by-pin diagnostics. Simply connect the cable and press the SEL button for 2 seconds to start testing. LED indicators will sequentially check each pin and highlight faults (e.g., open or short circuits on Pin 2 or Pin 3), enabling quick identification and resolution of cable issues.
- Phantom Power Checker: Verify phantom power voltage within a range of 24V to 52V using clear LED indicators: Solid LED: Voltage between 44V-52V (line OK). Flashing LED: Voltage between 24V-44V (line OK). This ensures your phantom-powered microphones and devices receive the correct voltage, preventing performance issues or equipment damage.
- USB-C Rechargeable: Compact and portable, the AT-1 features a USB-C charging port and a built-in rechargeable battery that fully charges in 1.5 hours. A low battery warning ensures uninterrupted operation, and the device supports use while charging.
