INSTALLATION/SETUP
This microphone is a USB (Universal Serial Bus) device-meaning this is a plug- and-play microphone that will interface with Windows and Macintosh computers without the need for any special drivers. The MXL AC-404 will operate with both USB 2.0 (high speed USB) and USB 1.1 data buses. 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 includes a headphone jack that accepts most headphones; however, the maximum headphone volume will vary by manufacturer and model so care should always be exercised when first plugging in your headphone.
