Perfect for custom audio projects

This adapter made wiring my DIY speaker setup incredibly easy. The terminal block holds the wires securely, and the 1/8" plug fits snugly into my source.

Reliable connection

No crackling or loose connections after weeks of use in my home studio setup. Highly recommend for anyone needing a clean adaptation.

Solid build quality

Good sturdy plastic housing. I wish the terminal screws were slightly larger for easier tightening with small screwdrivers, but it works well overall.

Good value

Does exactly what it says. The connection is stable, though the plastic feels a bit light. For the price, you can't complain.

Exactly as described

Needed a quick way to adapt a standard headphone jack to screw terminals for a prototype. This 2790 connector did the job perfectly without any signal loss.

Great for repair work

I use these in my repair shop for temporary testing of audio equipment. The 3-position layout is standard and very convenient.

5 FAQ

Q: Is this compatible with 3.5mm jacks?

A: Yes, the 1/8" plug is synonymous with the 3.5mm standard jack commonly found on consumer audio devices.

Q: Does it come with a mounting bracket?

A: The unit includes integrated mounting tabs on the housing for screw mounting, but separate brackets are not included in the package.

Q: Can I use this for high-power speakers?

A: No, this connector is rated for low-voltage line-level signals (2 Amps max). It is not suitable for driving high-power passive speakers directly from an amplifier output.

Q: Can this handle balanced audio signals?

A: Yes, the 3-position design supports Tip, Ring, and Ground configurations suitable for balanced mono or unbalanced stereo applications depending on your wiring.

Q: What size screwdriver do I need for the terminals?

A: A small flathead screwdriver with a blade width of approximately 2.5mm to 3mm works best for tightening the terminal screws.
