Connection structure and design details连接结构与设计要点
Use the 3.5mm trs to 5-pin din midi branch cable form as a starting point and confirm these design points against drawings and the actual equipment.以3.5mm TRS转五针DIN MIDI分支线的结构形式为起点，结合图纸和实际设备确认以下设计要点。
End transition layout端头转接与组合
The assembly organizes a transition or combined connection, with end directions, transition sections and fixing arranged around the equipment positions.组件以转接或组合形式组织连接，可围绕两端设备位置安排端头方向、过渡段与固定。
Conductor and insulation selection导体与绝缘选配
Select conductors and insulation from circuit loads, diameter limits, bending and exposure. A material name does not replace ratings or validation results.从电路负载、外径限制、弯曲方式与环境条件选择导体和绝缘体系；材料名称不应直接代替额定参数或验证结果。
Interface and function review接口与功能确认
Equal TRS/TRRS diameter does not establish matching wiringTRS、TRRS同外径不能证明线序一致

PRODUCT QUESTIONS产品问答
Product & customization questions产品与定制常见问题
Does an XLR connector always mean balanced audio?使用 XLR 接口就一定是平衡音频吗？
No. XLR describes a connector family. The equipment circuits, pin assignment, cable pair and shield termination determine whether the path is balanced.不一定。XLR 描述的是接口家族，是否平衡取决于设备电路、针脚定义、线对与屏蔽端接。
Is a TRS cable always stereo?TRS 线一定是立体声吗？
No. TRS can carry stereo unbalanced audio, mono balanced audio, insert send/return or a proprietary circuit. Confirm both equipment endpoints and the pin map.不一定。TRS 可以承载非平衡立体声、平衡单声道、插入发送/返回或专用回路，必须确认两端设备和针脚。
Can microphone cable be used for loudspeakers?麦克风线可以用作扬声器线吗？
It should not be assumed. Loudspeaker circuits can require much larger conductors and different current, temperature and connector considerations than low-level microphone paths.不能直接假设可以。扬声器回路通常需要更大的导体，并具有不同的电流、温度与接口要求。
