默认 我准备用3套AV功放推3套喇叭

由于全是地摊货所以效果一般。

而且全在那立着不用也是浪费。

现在设想把3套AV功放及3套箱子组合起来。

输入是同一个双声道信号。这里选AV功放非更老的是因为可以利用光纤或者同轴传信号。

每套AV功放单独推一对箱子。

理论上能达到2x300瓦。

效果不好说。如果他们的延时差不多的话还好说否则可能互相抵消。

有没有这样用的谈谈看法?

我怎么觉得会很难用啊? 各个通道音量tracking怎么实现呢?

用一个前置控制音量然后分配到功放。

理论上不会差到哪去。

那样不就只能用模拟信号送去功放,用不了你上面讲的光纤/同轴了吗?除非你在数字域控制音量,可以保持数字互连方式,可是那样搞人为损失信噪比啊。

其实他们之间完全是独立的。也没有必要同步音量。

甚至开不开机都无所谓。

想找事就3甚至5台功放加5套喇叭全开。否则开一台也完全没问题。
