XLR Cable Tester

Tests whether 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.
