Detail 01
TRS on the single end
Three conductors carry two signals. On an insert jack that's send and return through one plug.

Independent shopping perspective
Four-meter Y-cable, one 1/4-inch TRS end splitting to two 1/4-inch TS ends. The standard insert cable for a mixer channel, or a stereo-to-dual-mono breakout.

Strong match

What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
Three conductors carry two signals. On an insert jack that's send and return through one plug.
Detail 02
Each leg is unbalanced mono — send and return on an insert, or left and right on a stereo breakout.
Detail 03
Reaches a rack beside or behind the desk without a coupler, with slack for dressing the run.
Detail 04
It parallels connections with no buffering or isolation, so splitting one output into two inputs loads the source.
Detail 05
No hum rejection. Keep it away from dimmers, power runs and lighting cable, especially at full length.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Yes, that's the common use. The TRS plug goes into the mixer's insert jack and the two TS legs go to the outboard unit's input and output.
It depends on how your desk wires the insert jack, usually tip. If nothing comes back through the loop, swap the two legs and try again.
Not a good idea. It ties both outputs together with no isolation, which loads them down and can change the tone and level. Use a mixer or a proper splitter.
No. The TRS end carries two separate unbalanced signals rather than one balanced signal, and each TS leg is unbalanced mono.
