Configurazione e installazione
Follow these steps for proper installation of your Herdio ceiling speakers:

- Crea ritaglio: Use the provided cutout template to mark the exact opening size on your ceiling. Carefully cut the hole using an appropriate tool.
- Rimuovere la griglia: Gently pry off the speaker grille using a thin, flat tool to access the mounting screws and wiring terminals.

The speaker's detachable grille is shown, emphasizing its thin profile and the ease with which it can be removed for installation or maintenance.
- Collegare i cavi degli altoparlanti: Collega i cavi dei diffusori dal tuo amplifier to the terminals on the back of the speaker. Ensure the red wire connects to the positive (+) terminal and the black wire connects to the negative (-) terminal. Maintain consistent polarity for all speakers in your system.
