How to choose the power supply?the power supply with the board is very key, the selected power supply ripple must be small, ripple large power supply will lead to power amplifier bottom noise, there is a current soundif you only have 9v12v or 1a 2a power supply, you can also use it but with low powerit is recommended to use 18v19v24v power supply with current above 5athe higher the voltage, the higher the current, and the higher the power outputif you are above 19v 5a, no problem with 8-10 inches, power must be highly valuedspecifica:item type: amplifier boardmodel: zk-tb21materiale: componenti elettronicicolore: blackversione bluetooth: 550w(r and l channel), max1chip: tpa3116d2(with am anti-interference function)power: dc12-24v/5aadapter speaker: 20-100w, 4-8ωoutput power: maxif you only have 12v 1a, you can have 3-4 inch speakershow to select speakers?about the speaker type: commonly used speakers are generally 4-8 ohmswhen using it, choose the volume close to the maximum, which may cause distortion and affect the sound qualityif the current is too low and the horn cannot be brought up, the voltage will be pulled down, which will lead to abnormal operation or poor sound quality100w(subwoofer)quantità : 1 pzil pacchetto include:1 x amplifier boarddomanda e risposta:1if the voltage is too low and the sound is amplified, it will easily cause sound distortion0 (nessuna schermatura, 10 m)sensibilità di ingresso: 500 mvingresso audio: aux+bluetoothchannel: 2
