Photo and product description
TDA7297功放板,带接线柱，2.0双声道15W+15W，可接4-8欧10-50W的扬声器，小身材大音量，应用范围广。
电压：直流电9-15V，推荐直流电压12V，电流2A以上
功率：15W+15W
输出阻抗：4-8欧
◆本板优点：开机无电流冲击声，高保真无静态噪音！音质超级好--高音细腻、柔和、通透、无明显刺耳；低音结实、饱满、有力、收放自如。最近有小部分客户反映说本板有点噪音，大多是电源问题没有解决的缘故。经测试，用12V2A以上电瓶或12V30W以上变压器供电一点噪音都没有，如果用开关电源或别的可变电源供电，由于线性不好可能会产生低噪
◆本功放板核心为原装进口TDA7297双声道功放芯片，欧洲著名的SGS-THOMSON意法微电子公司出品。电源设计为直流电供电，可用12V的电瓶直接供电，电压范围：9-15V，推荐电压12V，输出功率高达15W+15W，峰值功率达30W+30W，体积很小声音却超级震撼，适用任何场合。
