看看PEAVEY官方论坛上的人说的. 他说我应该调整到8欧. 但是我现在拔了212的SPEAKER. 只用JSX 412. 所以应该也用16欧对吧. 如果按照他的说法, 当我把212的SPEAKER和412的SPEAKER一起连的时候就必须调整到8欧了对吧. 也就是说在这种情况, 如果我连接的是16欧MONO的INPUT, 这样一来CAB的四个喇叭和212本身的两个喇叭都应该是工作的. 对吧. 现在情况复杂了. 真实难懂哦.
Hello,
The interanl impedance load of the JSX 212 is 16 ohms. So, when no
external speaker is connected then it should be switched to 16. The 412
extension speaker is also 16 ohms. So, when it is connected to the JSX
212 then the switch should be set to 8 ohms. Because two 16 ohm speaker
loads connected in parallel equals 8 ohms.
Since the 412 is a 16 ohm mono enclosure the all four speakers should
be working inthe 412. So, my best guess is that there is a loose wire in
the cabinet. This probably didn't cause a problem with the amp but it
needs to be taken care of. Thanks,
Aubrey |
