How to build a custom EMU 0404 breakout cable for high end audio applications If you own an EMU0404 and use it for audiophile listening then it s pretty obvious the stock breakout cable is pretty weak It s flimsy and of poor quality and then you need a weird 1 4 to RCA to hook it up to your amp no fun So far it sounds great Here s what I used to make mine though you can substitue lower or higher quality parts where you see fit Silver plated copper mil spec wire teflon housing WBT 4 silver solder Tinned copper braided shielding Radio Shack DB9 D Sub connector Radio Shack D Sub Metal Hood Dayton Audio Pro Fi locking RCA plugs Some Techflex heatshrink to make it pretty To start you ll need the pinout for the breakout cable Here it is with the important ones in bold from the Head Fi forums courtesty of Stroog 版本一 1 nothing 2 right output 3 left output 4 left input 5 right input 6 right output ground 7 left output ground 8 left input ground 9 right input ground 版本二 其实是一样的 这卡是平衡输出 Analog 模拟接口 1 n c 2 OUT R tip 3 OUT L tip 4 IN L tip 5 IN R tip 6 OUT R sleeve 7 OUT L sleeve 8 IN L sleeve 9 IN L sleeve Digital 数字接口 4 SPDIF out gnd 5 SPDIF out signal 6 SPDIF in signal 13 SPDIF in gnd So what exactly does that mean Well if you get the Radio Shack D Sub connector each pin is marked Just solder each wire to the correct pin Otherwise here s a handy diagram I came across online The top left pin is 1 the next one over is 2 and so on When soldering to the back of the DB9 connector remember it will be in reverse so the top right will be 1 Instructions are below please feel free to comment or email me if you have any questions If you would like contact me for a quote to build this cable for you using the same configuration I used for this tutorial 就是普通 9 针串口 会了这个 会了这个 M Audio 的的 delta 卡同理 我只给出引脚定义卡同理 我只给出引脚定义 就是普通 15 针串口 Here is the pinout for the Delta 44 66 1 analog out1 模拟输出声道 1 左声道 2 analog out2 模拟输出声道 2 右声道 9 shared ground shield for out1 and out2 这是左右声道的公共地 下面同理 3 analog out3 4 analog out4 11 shared ground shield for out3 and out4 13 analog in1 6 analog
