Product name: Bluetooth 5.0 power amplifierBluetooth version: JL-AC6925A-5.0Power supply voltage: DC12-24VSupply current: 3-5AOutput power: 26Wx2/ 8 ohmNote:1. The power supply of the power amplifier board requiresDC 12-24V 3A regulated switching power supply (the battery and charger, transformer and AC switching power supply cannot be used for testing)2. DC12V 3A (above) power supply, the maximum output power is 2x15W /8 ohms (full volume may be distorted after turning on)3.DC24V 3A power supply, the output power can reach up to 2x26W /8 ohm continuous power (4 ohm speakers may be protected) (all volume may be protected)4. Do not connect to a battery with a standard 24V, because the battery may exceed 25V after being fully charged, and the capacitor on the board is 25V, there is a risk of explosion 5. Do not connect the 24V battery of a large truck, because the charging voltage reaches 28-32V when the truck is on fire, and it will burn colour: black + greenMaterial: PCB + plastic + metalPackage Contents:2 x Power Amplifier BoardOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
