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 TesterEasily 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.
