1. Power Supply Instructions: If the power amplifier's output power reaches 50 W + 50 W, the power supply must be 24 V, meaning 120 W, i.e., 24 V must be 5 A. A 12 V power amplifier will also work, but the output power will be significantly lower. When using a 12 V power amplifier, ensure you select the appropriate power supply according to the current requirements. 2. Horn Wiring Instructions: Interface descriptions and polarity information are provided on the main board. The plus sign (+) indicates the positive terminal. Connect the positive terminal of the speaker or passive speaker to the negative terminal of the speaker or passive speaker. Never reverse the polarity, as this will affect the speaker's phase and significantly impair sound quality and the listening experience. Note: When using an unpopulated circuit board without obstructions, an external antenna is not required. The reception range is then 10-20 meters. When installing a metal enclosure, an external antenna must be added, as the enclosure otherwise strongly blocks the signal and reduces the reception range to 1-3 meters. After adding an external antenna, the range is 10-20 meters. When installing a plastic or wooden enclosure, an external antenna is not always necessary. Depending on your requirements, choose whether you want to include an external antenna kit.
