สตูดิโอโปรดิวซ์เพลง: การตั้งค่าสายเสียง

## Core Signal Chain

```
Microphone → XLR → Audio Interface → USB → Computer → Monitor Speakers
```

## Essential Audio Cables

| Cable | Use | Connector |
|---|---|---|
| XLR | Microphones | 3-pin XLR |
| TRS 1/4" | Monitor speakers | 6.35mm TRS |
| TS 1/4" | Guitars, keyboards | 6.35mm TS |
| MIDI DIN | Old synths/controllers | 5-pin DIN |
| USB-C | Audio interface to PC | USB-C |
| 3.5mm TRS | Headphones | 3.5mm |

## Audio Interface Connection

- **USB**: Most common, works for 2-8 channel interfaces
- **Thunderbolt**: Lower latency, needed for 16+ channels
- **PCIe**: Lowest latency, studio-grade (RME, UAD)

## Common Mistakes

1. Using unbalanced (TS) cables for long monitor speaker runs — use balanced (TRS)
2. Cheap XLR cables picking up interference — invest in Mogami or Canare
3. USB 2.0 audio interface on a USB 3.0 hub — can cause clicks and pops
4. Running audio and power cables parallel — causes hum
