*功放报价在500元到上千元不等；卡拉OK功放分为合并式卡拉OK功放以及前后级分开的组合，按照话筒效果类型分为传统ECHO和DSP。其实传统的ECHO也是早期的DSP处理器，限于当时的技术需求及成本控制，性能不高，应用范围受到较大局限。

高档次KTV至少三千以上吧，普通KTV千元不等。一般的家用一两千算很好了。甲类功放是指在信号的整个周期内（正弦波的正负两个半周），放大器的任何功率输出元件都不会出现电流截止（即停止输出）的一类放大器。甲类放大器工作时会产生高热，效率很低，但固有的优点是不存在交越失真。单端放大器都是甲类工作方式，推挽放大器可以是甲类，也可以是乙类或甲乙类。乙类功放是指正弦信号的正负两个半周分别由推挽输出级的两“臂”*流放大输出的一类放大器，每一“臂”的导电时间为信号的半个周期。乙类放大器的优点是效率高，缺点是会产生交越失真。甲乙类功放界于甲类和乙类之间，推挽放大的每一个“臂”导通时间大于信号的半个周期而小于一个周期。甲乙类放大有效解决了乙类放大器的交越失真问题，效率又比甲类放大器高，因此获得了极为广泛的应用。

几百到几千的都有。（一套--功放、音箱、麦克风）贵一点的，音质好很多。*，10个包房，买的音响是1000一对，攻放1600一个。话筒160一对。低音炮1500一个。不知道你规模多大，档次多高，所以价格不好说。这个东西没有上限的。
