VII. Common Hardware Issues

1. What microphone cable do I need?

Most studio mics use XLR cables.

USB mics use a USB cable, no interface needed.

Lavalier and headset mics may use TRS or mini-XLR, depending on brand.

2. Why does my mic sound weak or distorted?

• Check for correct phantom power (48V) if it’s a condenser mic.
• Make sure input gain on the interface isn’t too low or too high.
• Try another cable or input channel.
• Check the polar pattern switch (if applicable) isn’t set incorrectly.

3. My mic is not recording. What should I do?

• Confirm the mic is plugged in and recognized by the interface.
• Make sure it's assigned to the correct input channel in the DAW.
• Record-enable the track.
• Confirm phantom power is ON only if using the Rode condenser mic.
• Test the mic with another system if unsure.

4. How do I connect amps correctly to avoid grounding issues or static?

• Use balanced audio cables (XLR or TRS) when possible.
• Avoid pluging the amp onto a multicontact that is shared with other devices.

• When possible, plug on a single socket on the wall.
• Avoid running audio cables parallel to power cables.
• Avoid shaking or droping the amp as parts may become loose inside the cabinet.
• Never remove a ground pin from a power cable, this is dangerous.
• Never connect a 3-prong cable to a 2-prong contact.
