Thank you for purchasing the MXL
neering and manufacturing. They are designed to provide you with outstanding performance and exceptional
value. For best results, please take a few moments to review this literature.
INSTALLATION/SETUP
The AC-404-LED microphone is a USB (Universal Serial Bus) device that will interface with Windows® and Mac®
computers without the need for any special drivers. The MXL AC-404-LED is compatible with USB 3, USB 2 and USB
1.1 ports. We recommend connecting your microphone directly to the computer's USB port as opposed to using a
USB hub as USB hubs can interfere with the performance of various USB devices.
The MXL AC-404-LED includes a headphone jack that accepts most headphones; however, the maximum head-
phone volume will vary by manufacturer and model so care should always be exercised when first plugging in
your headphones.
SETUP FOR USE WITH MAC®
After connecting the AC-404-LED to an unused USB port, go to: System Preferences > Sounds Icon.
To use the built-in headphone jack on the AC-404-LED as the audio output, click on the Output tab then select the de-
vice named USB Audio CODEC. You can adjust the headphone volume by moving the fader labeled Output Volume.
Next, click the Input tab and select the device named USB Audio CODEC. You can adjust the microphone volume
by moving the Input Volume slider. The gain of the microphone is very sensitive. For most applications the slider
will be set toward the left.
Your computer is now setup to use the MXL AC-404-LED USB Boundary Microphone. Some applications will require
additional settings to be changed within the program.
SETUP FOR USE WITH WINDOWS®

fault audio device, go to:

Questions and answers
Hello, I just purchased the AC 404 microphone for a Webex meeting and when we plugged it in the microphone worked so they could hear us but the computer speakers no longer worked. Can this still be used without having to connect to the headphones, I need everyone in the room to hear the responses from those online. After Webex ended I opened up a YouTube video and the speakers worked fine with the mic connected. Any idea where I need to go to change the settings?
To ensure your computer speakers work during Webex meetings while using the MXL AC-404 LED microphone, follow these steps:
1. Set the Microphone as Default Recording Device
- Connect the MXL AC-404 LED to an available USB port.
- Open Control Panel > Sound and go to the Recording tab.
- Select USB audio CODEC (the microphone) and click Set Default.
- Adjust the microphone gain if needed by double-clicking the USB audio CODEC, selecting the Levels tab, and adjusting the slider.
2. Set Computer Speakers as Default Playback Device
- Open Control Panel > Sound and go to the Playback tab.
- Highlight your computer’s speakers and click Set Default to ensure sound output is directed to them instead of the microphone’s headphone jack.
3. Check Webex Audio Settings
- Open Webex and go to Audio Settings.
- Ensure Microphone is set to MXL AC-404 LED (USB audio CODEC).
- Ensure Speaker is set to your computer’s speakers.
Click Apply or OK for changes to take effect.
