TDA7294 + LM3886 5.1-Channel Power Amplifier Board AC Double 20V-24V
- Front input capacitance and interstage coupling capacitors usedCBBTop capacitor 3.3 UF
- The main filter capacitor using Black Edition Capacity10000UF/50V * 6 With a total capacity of 6WUFRectifier using domestic 25A And above flat bridge, to ensure strong support for a steady stream of power.
- Resistance selection Rings metal resistance, the main circuit employs a precision± 1%The metal film resistors rings, ensure the machine a good signal to noise ratio.
- PCBAdoption1.6mmThick double-sided sheet,2.0Oz copper thickness, HASL whole process to ensure that the size of the current through the good performance. TopPCBQuality.
- Optional hole platingICSeat, not the generalICSeat, more durable!
- Subwoofer in part by two new components TDA7294 BTL output, strong power! Other channels were served by the five LM3886, each channel has a LM3886TF support.
- The entire circuit board trace layout are very strict and reasonable, the overallPCBTraces using a little grounding. The amplifier board is stable and reliable, high output power; beautiful mellow sound, open sound field.
- Three-dimensional sense of strong, powerful low-frequency sound calm, very good signal to noise ratio, wide dynamic range; details clear, excellent transient response, both cope easily play a variety of music, sound reproduction in the home environment has a very good performance.
- Supply voltage:AC double 20V-24V (recommend more than dual 24V/400 W)
- Output Power: 50W * 2(4OhmLeft and right channels)+160 W (8Ohm Subwoofer)
- PCB Size: 306mm* 97mm
