Radial Engineering R800 1102 ProD2 2 通道被动立体声直盒，1 年免费延长保修
所有音乐都提供 1 年免费延长保修。
Radial ProD2 是一款紧凑型立体声直插盒，专门用于解决将立体声键盘连接至专业音频系统的需要和挑战。 此被动式 DI 有两个独立的通道，分别为艺术家舞台放大输入和插图，为 PA 系统提供两个完全隔离的输出。
设计核心是两个高性能 Eclipse ET-OTHER 变压器。 这些产品提供 20Hz 到 20kHz 的性能，低于 18kHz 的 1.5dB 偏差，并且能够承受巨大的信号水平而不会失真。 与信号超出铁路电压时过载的活动电路不同，变压器会饱和。 这会产生一种令人愉悦的效果，自然地倒掉音调，像微妙的限制器，在将 ProD2 与能够产生过多的动态数字钢琴、采样器和鼓机连接时，它尤其有优势。 Transformers 特别适合消除由地面环引起的卷发和发泡。
与所有 Radial 产品一样，ProD2 构造坚韧，可应对专业旅行的严苛。 14 号钢超硬 i-beam 骨架架消除了外部应力以弯曲敏感 PC 板并导致过早的焊接关节失效。 创新的书末设计在连接器和开关周围创建一个保护区，进一步增加使用寿命。 底部的防滑垫增加了机械隔离和电气绝缘，从而进一步减少噪音的机会。
Radial ProD2 的温暖声音、传奇的构造质量和紧凑的设计使其成为当今*流行的立体声直盒子。

Additionally, there was this TERRIBLE BUZZ in the speakers. NO matter what volume level you put the drum kit on, the buzz was still there (Same level). When we pulled the drum volume down on the mixing board, we could reduce the volume of the buzz, but not eliminate it altogether, and then, all the other instruments/vocals were overpowering the drums.
So i did some research and concluded that we must be experiencing a "Ground Loop". After reading reviews on this product, i though i would give it a try. I installed this between the drum kit and the snake. When i powered on the sound system, i was shocked that there was NO SOUND. No buzz, no hum, no noise of any kind. it didn't even sound like i had turned anything on. Our sound system has NEVER been that quiet, even before the remodel. My first thought was "Man, this thing isn't working, now i have NO sound". As i walked toward the box to start trouble shooting, it occurred to me that i should at least TEST the drums first. Guess what, they WORKED. The box was just THAT GOOD. Praise God. Additionally, this also seemed to fix the Popping / Clipping volume issue we had previously as i can now put the drums back on the default volume level of 13 with no issues.
A friend lend me one exact model and after recording we compared the signals recorded with others using a cheaper DBX direct box, and they were almost identical coming out of a noisy Roland D50, both boxes canceled some of the noise and the rest was cleaned with a VST.
I would say Amazon did a great job with the return, probably I was unlucky but after testing a working unit this seems is just legacy memories of a great brand, buy a cheaper one and you can spend the difference in good quality cabling here which is in some cases more important.
Don't take a chance on other brands or knockoffs. Get Radials.
