Choosing a Microphone with Both USB and XLR Outputs

Before you start

A microphone with both USB and XLR outputs gives you two ways to connect: USB for a direct digital connection to a computer, phone, or tablet, and XLR for a balanced analog connection to an audio interface, mixer, or recorder. This article covers only the selection and connection steps that are relevant to this type of microphone. The process runs locally on your equipment and does not require an online service unless your recording or video call software uses one.

Before choosing a model, check the ports on the device you plan to use. A USB microphone needs a compatible USB port and, in some cases, an adapter for USB-C or Lightning connections. An XLR microphone needs an XLR cable and a device with an XLR input that can supply phantom power if the microphone is a condenser model. Dynamic microphones usually do not need phantom power, but you should verify the requirement for the specific model.

Step-by-step instructions

Use one output at a time unless the product documentation states that both can be active together. Some microphones allow simultaneous USB and XLR use, while others route the signal to only one output. Start with the connection that matches your current recording device or interface.

For a direct USB connection, connect the microphone to the computer, open the sound settings, and select the microphone as the input device. On many systems the device appears with its model name. Set the input level so that your normal speaking voice peaks well below the maximum level without being too quiet. If the microphone has a physical gain control, adjust it first and then fine-tune the software input level.

For an XLR connection, use a balanced XLR cable between the microphone and the audio interface or mixer. Turn on phantom power only if the microphone requires it and only after the cable is connected. Set the interface gain so that a normal speaking level remains clean, then select that interface as the input device in your recording or conferencing software.

If the microphone exposes a sample rate setting, choose a value supported by your operating system and software. Common sample rates include 44.1 kHz and 48 kHz. Matching the sample rate between the microphone, interface, and software can help prevent clicks, pitch changes, or devices that do not appear as expected.

The USB and XLR paths are independent enough that a model may have different controls or monitoring behavior on each path. Check whether headphone monitoring is available on the microphone or through the interface, and keep the procedure reversible by testing the microphone on one output before changing system-wide audio settings.

Check the output

After connecting the microphone, record a short clip using the same software you plan to use for the real task. Speak at your normal distance and volume, then listen back for obvious distortion, excessive room sound, or a signal that is too quiet. Use the software meter if available: a healthy level usually keeps speech clearly above the noise floor but below the clipping point.

Check which device the software is actually using. A successful connection does not guarantee that the correct input was selected automatically. In video call applications, confirm the microphone choice in the application settings rather than relying only on the operating system setting.

Format and quality limits depend on the microphone, interface, software, and connection. A higher sample rate does not automatically mean better sound for speech, and USB audio may expose only the formats supported by the microphone. If the recorded file sounds thin, distant, or noisy, compare the same setup with a known recording application before changing the microphone.

Common problems and next steps

If the microphone does not appear as an input device, check the cable and port first. Try a different USB cable or a different XLR cable, and connect directly to the computer instead of through a hub. Close and reopen the audio software, then check whether the operating system detects the device.

Low or absent input level on XLR is often caused by phantom power being off for a condenser microphone, by a cable that is not fully seated, or by gain being set too low. On USB, check the input level in the sound settings and any physical gain control on the microphone. If the level is still unusable, test the microphone on another device when possible.

Background noise can come from room tone, computer fans, or an input level set too high. Move the microphone closer to the source and reduce gain before relying on software noise reduction. If hum appears only on the XLR path, test the cable and interface, and keep audio cables away from power cables.

If sound is distorted, lower the gain or input level and move slightly farther from the microphone. If the signal is clean on one output but not the other, the issue is likely in the cable, interface, adapter, or software path rather than the microphone capsule itself. When one output works and the other does not, use the working path to confirm the microphone functions before replacing other equipment.
