6.35mm TS Mono vs TRS Stereo Y Splitter Cables

Choosing between a 6.35mm TS mono and TRS stereo Y splitter cable depends on your signal type. This guide compares two common Y splitter cables and explains which one fits your setup.
Quick answer
If you need to split a mono signal into two outputs, choose the TS mono Y splitter. If you need to break a stereo signal into two separate mono channels (for insert points or effects), choose the TRS stereo Y splitter.
The key difference: signal type matters
A TS mono Y splitter takes a single mono source and sends it to two destinations. A TRS stereo Y splitter does the opposite: it takes a stereo signal (carried on a single TRS connector) and splits it into two discrete mono channels. Choosing the wrong one can cause phase issues, signal loss, or no output at all.
For example, if you use a TRS stereo splitter on a mono guitar signal, you will only hear one side of the split. Conversely, plugging a TS mono splitter into a stereo headphone output will sum both channels into a mono signal, losing stereo imaging.
Insert cables: a common use case
Many mixing consoles use a single TRS insert point that carries both send and return on one connector. A TRS female to dual TS male Y splitter (like product 2426787) separates those two signals into separate TS cables so you can connect a compressor or EQ. The tip carries the send, the ring carries the return, and the sleeve is common ground.
If your console uses separate send and return jacks, you would instead use a TS male to dual TS male Y splitter (like product 2426788) to split a mono send signal to two processors or to route a mono signal to two amplifiers.
Trade-offs at a glance
- TRS Stereo Y Splitter (2426787): Splits a stereo TRS signal into two mono TS signals. Used for insert points where the send and return share one connector. Cannot combine two mono sources into stereo. Check if your console insert jack is TRS or separate send/return.
- TS Mono Y Splitter (2426788): Splits a mono TS signal into two identical mono outputs. Used to feed multiple amps or processors from one mono source. Cannot split a stereo signal. Ensure your source is mono – a stereo source will lose one channel.
- Connector direction: The TRS splitter has a female input (accepts a male TRS plug) and dual male TS outputs. The TS splitter has a male input (plugs into a female jack) and dual male TS outputs. Verify your gear’s jack gender. Check both cable ends against your equipment before buying.
