Anthem M1單聲道後級
加拿大的Anthem在多聲道領域具有技術領先地位，在擴大機的設計上，也有獨到一面。很少有擴大機能夠像他們一樣，端出這樣驚人的性能規格。
怎麼個驚人法？Anthem M1單聲道後級，在對應8歐姆負載下，可以輸出1000W的功率，當負載阻抗降到4歐姆，輸出功率就倍增到2000W。
而且，在高輸出功率下，還能維持低失真，這就更不容易。
根據原廠公布的數據，M1在10W輸出以內，失真率僅有0.01%，這還不稀奇，驚人的在後頭，100W輸出下，總諧波失真率還小於0.03%，就算是1000W全功率輸出，失真率還是維持在0.06%以下，這的確是世間罕見。

|
|
| Where mains voltage is 120V, one dedicated 15A circuit per amplifier is recommended depending on speaker. A 20A circuit is adequate for two amplifiers playing music where speaker impedance is 8 Ω. This product operates from a single phase AC power source that supplies between 108V and 264V at a frequency of 50 or 60 Hz. | |
