3.5mm TRS Audio Male Plug to 3 BNC Male Splitter Cable for CCTV Camera System TRS to BNC Adapter Cable
1. Product Introduction
3.5mm TRS to 3x BNC Splitter Cable is an audio/video signal distribution cable with a 3.5mm TRS (stereo) audio plug on one end and 3 BNC (Bayonet Neill-Concelman) male interfaces on the other end, suitable for converting audio signals to BNC interfaces (commonly used in video or professional audio equipment). This cable is usually used for monitoring, broadcasting, laboratory equipment or professional audio and video systems.
2. Advantages
High compatibility: suitable for a variety of equipment, such as surveillance cameras, oscilloscopes, audio analyzers, etc.
Stable transmission: BNC interface provides good anti-interference ability and reduces signal loss.
Flexible distribution: 1 to 3 design, multiple devices can be connected at the same time.
Durable design: high-quality metal shell and shielded wire to reduce electromagnetic interference (EMI).

4. Application scenarios
- Monitoring system: connect DVR/NVR with BNC camera.
- Laboratory equipment: audio input/output of oscilloscopes and signal generators.
- Broadcasting equipment: professional audio distribution or synchronous signal transmission.
- Audio and video engineering: mixers or converters adapted to different interfaces.
5. Purchase suggestions
Confirm the interface type: make sure the device supports 3.5mm TRS (stereo) and BNC interfaces.
Cable quality: choose cables with shielding to reduce interference.
Length selection: choose the appropriate length (1m/3m/5m, etc.) according to the usage scenario.
6. Safety precautions
Avoid excessive bending: prevent internal wire breakage.
Dust and moisture proof: BNC interface is easily affected by the environment, it is recommended to keep it dry and clean.
Impedance matching: some professional equipment may require 75Ω or 50Ω impedance matching, and compatibility needs to be confirmed.
Plug-in method: BNC interface adopts bayonet design, rotation lock, avoid forced plug-in.
7. Frequently Asked Questions (FAQ)
Q1: Can it be used to transmit video signals?
A: Yes, but you need to confirm whether the device supports composite video (CVBS) signal transmission.
Q2: Does it support balanced audio?
A: The 3.5mm TRS interface is usually unbalanced stereo, and the BNC interface needs to decide whether it supports balanced signals based on the device.
Q3: Do the three BNC interfaces output the same signal at the same time?
A: Yes, the 1-to-3 design is parallel output, and the signals are the same.
Q4: Can it be used for microphone input?
A: You need to confirm whether the device supports 3.5mm microphone input (usually requires additional power supply).
8. Summary
3.5mm TRS to 3x BNC Splitter Cable is suitable for professional audio and video signal distribution, especially in monitoring, laboratory and broadcasting fields. When purchasing, pay attention to interface compatibility and cable quality to ensure stable transmission.
High-quality flame-retardant materials: polymer materials have the advantages of flame retardancy and high temperature resistance; phosphor bronze gold-plated/tin-plated, with the advantages of wear resistance and corrosion resistance. High-tech anti-oxidation technology: improve the anti-oxidation and anti-corrosion capabilities, and maintain the characteristics of the metal surface.
99.9% oxygen free copper material, copper core, non flammable and safer to use. The outer skin is made of brand new PVC material, which is soft, durable, effectively oxidized, odorless, safe to use, and can be purchased and used with confidence.
1. PVC environmentally friendly high-flexible wire tensile shield: 10,000 swing tests, 72-hour aging tests, 4-30KG tensile tests have a longer service life and always maintain flexibility under the protection of a strong outer jacket.
2. Multiple shielding and high-speed transmission: thickened tinned copper core, plus aluminum foil metal shielding braided mesh, multiple shielding and anti-interference, serial communication data transmission in seconds.
3. Gold-plated contacts: anti-oxidation and anti-corrosion, internal gold-plated contact welding optimizes the transmission channel.
- Monitoring system: connect DVR/NVR with BNC camera.
- Laboratory equipment: audio input/output of oscilloscopes and signal generators.
- Broadcasting equipment: professional audio distribution or synchronous signal transmission.
- Audio and video engineering: mixers or converters adapted to different interfaces.
