Product Name: LM3886 2.1 Subwoofer Fever Level Amplifier Module (heat sink not included, please add heat sink before connecting to transformer). Size: 235 x 100 x 50 mm (L x W x H). Output power: 120 W (use a subwoofer with more than 8 ohms, not suitable for 4 ohms) + 68 W + 68 W 4-8 ohms. Supply voltage: AC 24 V-0-24 V (voltage can be selected between 22-26 V). Transformer requirements: power 250 W or more, more than 300 W is better (not suitable for virtual transformers). Note: without circuit, only with a circuit diagram. The amplifier board is designed to use LM3886TF as the core, complemented by a built-in low pass filter and left and right channel sound adjustment.
With four Siemens 3.3UF capacitors, smaller loss angle, excellent sound, high fidelity. The main filter capacitor consists of 6 Nover Gold audio capacitors with a capacity of 10,000 μF 50 V each and a total of 60,000 μF total capacitance, suitable for high, dynamic audio output power. Four LM3886 amplifiers for 2.1 channel output: 120 W + 68 W + 68 W. The amplifier uses four TI 5532 amplifier stages with mounting seats; can replace the different stages of the Fever op amp, easy to upgrade. With perfect protection circuit: voltage medium peaks, delayed start, protection of the loudspeakers. |
