Product Description
The AT-2 Audio Tester Pro is a compact and versatile all-in-one diagnostic tool designed for audio professionals, technicians, and engineers. Combining a signal generator, cable tester, input meter, and monitoring system, this device provides everything needed to quickly test and troubleshoot audio equipment in the field or studio.
Equipped with a built-in signal generator, the AT-2 can output a 1 kHz sine wave or pink noise through XLR, 1/4", and 1/8" connectors with selectable output levels. It also features an XLR cable tester to verify proper pin functionality, ensuring cables are operating correctly.
The integrated XLR input metering allows you to measure signal strength, while the phantom power check verifies voltage levels to ensure microphones and equipment receive proper power. For real-time monitoring, the unit includes headphone and speaker output via a 1/8" jack.
With fast USB-C charging and up to 4 hours of battery life, the AT-2 Audio Tester Pro is an essential tool for testing PA systems, mixers, cables, DI boxes, IEM systems, and more.
