This manual describes the operation of Yamaha GF24/12, GF16/12 or GF12/12 mixing consoles.
The manual begins with safety precautions, warning users to keep the unit dry, avoid pulling the power cord, and never modify the chassis. It also describes proper handling of damaged power cables and steps to take in case of fire, electric shock, or abnormal operation.
Subsequent sections detail the front‑panel and rear‑panel layout, channel controls, input and output connections, gain and EQ settings, AUX and GROUP routing, and the use of the PFL (pre‑fade listen) switch. The document includes wiring diagrams for XLR and TRS connectors and notes on phantom power and external effects insertion. This manual is written in Chinese.
