音樂聽起來就該像黑膠唱片播出來的一樣
不論您是在清理原本的唱片收藏或是透過黑膠唱片的復興而投入類比的懷抱，在您將唱針放到您最愛的唱片上的那一刻，都是獨特的體驗。為了保持黑膠唱片聲音的獨特溫暖，Duo 唱機前置放大器經過精心設計，配備最先進的開關模式電源和新的表面黏著電路板佈局，以減少不必要的噪音。
為什麼選擇專用唱機？
由於轉盤僅能產生較低的信號，因此並非所有 Hi-Fi 擴音機都能讓您直接連接到電唱機上。唱機前置放大器能提升信號到讓功率擴音機可以使用的地步。然而這個階段的挑戰在於容易加入噪音。
這就是我們圍繞特殊組件設計 Duo 的原因，這些組件可提供與黑膠唱片同步的溫暖而細緻的聲音，並且不會使移動磁唱頭的信號失真。開關模式電源透過在可聽頻率之外進行切換，大幅降低嗡嗡聲以提高性能，並且新的電路板佈局使用表面黏著元件來降低噪聲。
黑膠唱片。專為您預備
感謝 Duo 的整合性耳機輸入，我們可以私下享受黑膠唱片的溫暖音色。獨一無二的是，我們將 6.35 毫米耳機插孔直接整合到唱機中，因此當無法外放音樂時，您仍然可以好好地聆聽唱片。
整合性耳機輸出也代表您無需開啟擴音機即可為耳機提供電力，達成更環保的聆聽體驗。
注重細節
如果您收藏中有些唱片已經某種程度的磨損，則亞音速濾波器將有助於消除可能由黑膠唱片缺陷引起的低頻隆隆聲。將此與平衡控制相結合以處理電唱機中潛在的唱頭不平衡（這會造成左右聲道之間的差異），從而獲得具有準確聲場的詳盡體驗。
環保
Duo 唱機前置放大器本質十分環保，待機功耗不到 0.5 瓦，而且若 20 分鐘後未使用該裝置，則會啟動自動關機的功能。這反過來又為器材提供了相同的全球電壓，無論您身在何處，亦可兼容。

This is a brilliant piece of kit. I gave up hope that I could link my old 1970’s high quality turntable until I found the ALVA DUO - it is a great design very simple to use and wonderful sound quality. The added bonus of the headphone socket is a good touch

Hello,
Bought this to replace my tube Riia, use a Rega RP3 with a Nagaoka 200 , and YES this little gem really delivers , so happy with the sound and stereo soundstage and added clarity.
Tested with my reference platters and YES x 2 this is really well worth Riia.

I bought this to use Headphones on my Turntable. I'm using Denon High Output MC DL-110 and Sennheiser HD 660s2 with the Duo. First i pluged in on the MM like it should be and it was the best Sound i ever listen to. Then i tryed the HO MC on the MC in and the Sound is even better and more detailed. No Problem at all. I dont know why because i have absolutely no Idea what im doing. It sound great and im very happy to have this little pre/headphone amp.
