An impedance box is necessary for measuring the impedance of a loudspeaker. Listen Inc.’s impedance box contains a 0.25Ω resistance. This value is suitable for most loudspeakers, but may be easily swapped out for a different value by the user if speakers with a particularly high or low impedance are being tested. It is available with either XLR or 1/4″ balanced connectors. Please specify type of connectors when ordering.

测量一个扬声器的阻抗必须使用一个阻抗盒。Listen公司的阻抗盒包含了一个0.25Ω的电阻。该值适用于大多数的扬声器,但如果被测的扬声器具有特别高或低的阻抗,用户也可以很容易换成一个不同的值。它配有XLR或1/4寸平衡连接头。订购时请注明连接头的类型。

如果你使用的是SC Amp音频放大器或AmpConnect ISC测试一体机,则无需阻抗盒了,因为它已经包含在这两款产品中。
