ITEM NAME:XH-M257 High Power 420W Mono Digital Amplifier Board TDA8954TH HiFi Audio M A1E3 XH-M257 High Power 420W Mono Digital Amplifier Board TDA8954TH HiFi Audio M A1E3 power amplifier board using TDA8954TH chip with N-vidia industrial fan, the voltage part of the Ruby capacitors. After the pure design adriver more than inches 300W stage speakers! since it is a class A class design AD has both Class A heat, there are high efficiency class D, so they work with almost no heat! Using Attention: Please do not connect the power and the speaker freely. Please refer to the data provided by the product description for reasonable collocation. Otherwise, the function board will be damaged. Product Name: Digital Audio Amplifier Board Amplifier chip: TDA8954TH Input voltage: Dual AC24V ± 4V Input current:Greater than 5A and 300VA Input impedance:1 K Input signal: 1.8 V Number of channels: mono Magnification: 33 Output power: 420 W Output impedance: 4-8 Ω Job type: AD class Size: 110 * 102 * 30MM Net weight: about 245g color: blue Material: metal + PC Package Contents: 1*High Power 420W Mono Digital Amplifier Board Warm tips: 1. The product must be used to supply a double output toroidal transformer, the output is 3 wires. DC power supply can not be used. Output transformer for 24V200W above, the maximum voltage can not exceed 28V, otherwise it may damage the board. 2 Audio input can be 3 lines or 2 lines, but in the middle of the ground must be connected. 3. The biggest speaker output possible, 8 ohm recommended, also can use 4 ohms. 4. This section is a purely post-class issue, plus the tone border is better, but after adding tone border, the power supply tone of the board and power amplifier board must to separate. it can not be shared, otherwise there will be noise!
