How to use

Connect the MXL AC-424 to a computer using the USB cable and allow the operating system to recognise the device. Position the microphone on a flat surface or attached stand with the cardioid front facing the speaker for optimal pickup. Adjust the input level in your system sound settings or recording software to avoid clipping while ensuring clear signal strength. For multi-person meetings, place the microphone centrally to capture participants within its pickup area.

Usage recommendations

Place the microphone 20–40 cm from the main speaker and reduce reflective surfaces nearby to minimise room echo. Use software-level gain control rather than boosting in post-production for better signal-to-noise ratio. For group settings, test positioning and input levels before important calls to ensure balanced capture across participants.
