2. Detailed explanation of microphone cable connection method
1. Comparison of common microphone interface types
| Interface type | Applicable equipment | Wiring method | Advantages and Disadvantages |
|---|---|---|---|
| XLR (XLR) | Professional recording equipment | 1 ground wire 2 positive pole 3 negative pole | Strong anti-interference/requires transfer |
| 3.5mm TRS | Mobile phone/computer | Tip signal Ring ground wire | Portable/vulnerable to interference |
| USB | digital devices | plug and play | Driver-free/high latency |
2. Step-by-step wiring guide
XLR interface connection method:
① Confirm the microphone impedance (usually 200Ω-600Ω)
② Press "1 ground 2 positive 3 negative" to connect to the mixer
③ When using a balanced line, the wiring at both ends must be consistent.
3.5mm interface connection method:
① Distinguish between TRS (three-pole) and TS (two-pole) plugs
② Mobile phones need to use CTIA standard wiring (ground-right-left-microphone)
③ The front interface of the computer motherboard may require BIOS settings
3. Solutions to hot issues
| Problem phenomenon | Possible reasons | Solution |
|---|---|---|
| completely silent | Interface mismatch/insufficient power supply | Check phantom power/replace adapter |
| Obvious murmur | Poor grounding/damaged wires | Use balanced wire/replace shielding |
| Intermittent voice | Poor contact/driver issues | Clean interface/update sound card driver |
4. Suggestions for purchasing equipment (most searched models in the past 10 days)
| Microphone type | Popular models | Recommended interface | reference price |
|---|---|---|---|
| USB microphone | Blue Yeti | USB-A | ¥899 |
| XLR microphone | Shure SM58 | XLR interface | ¥1299 |
| cell phone microphone | BOYA BY-M1 | 3.5mmTRRS | ¥159 |
5. Professional tips
1. When using an XLR to USB converter, please note that the sampling rate needs to match (48kHz/24bit recommended)
2. When multiple devices are connected in series, impedance matching is key (input impedance > 5 times output impedance)
3. Recently popular live broadcast equipment (such as Elgato Wave series) supports hybrid interfaces, which can connect XLR and USB devices at the same time
With the above structured data and detailed instructions, you should already know how to connect the microphone cable. During actual operation, it is recommended to test first and then install it permanently. If you encounter any problems, please refer to the troubleshooting table in the article. Keeping cables neat and orderly can effectively improve audio quality and user experience.
