Based on the most common calls to Arcano tech support, here are fixes for the AM-EQ16:
| Problem | Most Likely Solution (From the Manual) | | :--- | :--- | | Channel is silent | Check the MUTE button. Is the PFL button pressed? (PFL kills the channel to the mains). | | Microphone is very low | Is the Pad button (if equipped) pressed? Is Phantom Power on for condenser mics? | | Sound is distorted | The Gain is too high. Turn it down. Also, check if the Main L/R fader is above the clip level. | | Feedback (Squealing) | Turn down the AUX sends. The mic is hearing itself in the monitor. | | Effects not working | Is the AUX 2 (Post) turned up on the channel? Is the FX return knob turned up on the master? | | One side of speakers is dead | Check the Pan knob on the channel. Is it centered? Check the cable; TRS vs TS matters. |
