CHALLENGER 250

Challenger 250是具有智能電源管理功能的高性能功率放大器,可提供獨特的聆聽體驗。

它們是我們成功於1987年推出的Monoblocus Challenger系列(115、150和180)的延續。Challenger 250達到了更高的清晰度和音質的完美水平。

與所有AudioValve放大器一樣,Challenger 250通過創新技術,精美設計和精確電路吸引了人們的注意。所有AudioValve放大器都是手工製作的產品,精度和精度均很高。

在Challenger 250的結合許多優點

自主研發的革命性專有ABR電路可獨立監控,影響和控制每個KT90管。所有Challenger 250均隨附KT90電子管,可以用與引腳兼容的Beam-Power五極管代替-ABR自動設置正確的偏置電流。這使客戶可以使用任何能為他/她創造最佳聲音的電子管。

另一個很棒的便利是電路在整個過程中都是完全平衡的,這使得這些放大器可以驅動各種揚聲器,從普通驅動器到奇特的靜電和色帶。挑戰者250尤其適合大房間中的大型揚聲器。享受它們所發出的嘶啞的聲音和真實的重播!無論您喜歡哪種音樂,Challenger 250都具有靈活性和多功能性。這些放大器將各種音樂-重金屬,流行,RocknRoll和古典-變成特殊的音樂。
