This split-unit tool offers maximum flexibility for all your audio testing!
Signal Generator
Outputs a 1 kHz sine wave or pink noise audio signal through XLR male, 1/4″, and 1/8″ connectors, with three output level options: -10 dB, -20 dB, and -40 dB.
XLR Cable Tester
AT-3’s split-unit design allows you to test long cable runs with one unit at each end, to make sure all three pins of the XLR cable are functioning properly.
XLR Input Metering
Measures the input volume level of the XLR female connector.
Phantom Power Check
Tests the output voltage of the phantom power and ensures both pins are functioning properly.
Headphone and Speaker Monitoring
When an audio source is connected to the XLR female / 1/4″ input, you can monitor the signal with headphones or speakers via the 1/8″ headphone jack.
HOLSTER POUCH
Also included are a 1/4″ male to 1/4″ male adapter, and a USB-C charging cable
