EVO ONE
All-in-One Wireless Streaming Speaker
从您的黑胶唱片集中采出每一寸的细节。这就是我们最高品质的 MM / MC 唱头放大器连耳扩 ; Duo 唱头放大器。
无论您正在拭去唱片上的灰尘,还是通过唱片复兴投入了模拟技术的怀抱,从您在最爱的唱片前放下唱针的一刻起,您都会享有一段独一无二的体验。为了保留黑胶唱片独特的温暖音色,Duo 声频前置放大器经过了精心设计,配有顶级开关式电源和全新的表面固定电路板布局,以减少额外的噪音。
唱片创造出的是低等级的信号,因此并非所有 hi-fi 放大器都能允许您直接与唱片播放器相连接。声频前置放大器可以增强这一信号,使其能在强大的放大器上工作。这一阶段的挑战在于这很容易增加噪音。
正因如此,我们运用出色的部件设计出了 Duo,它能够同步发出黑胶唱片温暖而又细腻的音色,且不会因为动磁式唱头而造成信号失真。开关式电源通过在音频之外切换而大幅降低嗡鸣声,提高了性能,同时新的电路板布局使用了表面安装的组件来降低噪音。
借助 Duo 集成式耳机的输出,您可以独享黑胶唱片的温暖音色。与众不同的是,我们在唱头放大器上直接集成了 6.35 mm 耳机插孔,让您在不能大声播放时,仍然可以沉浸在唱片中。
集成式耳机输出也意味着您无需因为要给耳机供电而打开放大器,这也是更加环保的听觉体验。
如果您所收藏的唱片磨损有些过度,那么亚音速过滤器将帮助您消除由乙烯基内部缺陷所造成的低频轰隆声。将其与平衡控制相结合,能够处理您的唱机中可能存在的唱头不平衡(这可能会导致左右声道之间存在差异),从而借助精确音场获得细腻的体验。
Duo 声频前置放大器将环保铭记于心,它的待机能耗只有不足半瓦,如果在20分钟内不再使用,还可以自动关机。这使得该装置能够兼容全世界的电压,无论您身处何方
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.
