3.5 mm to 2.5 mm audio video adapter

This adapter converts a single 3.5 mm 4-pole male plug into a 2.5 mm female socket. It lets you connect devices or cables with mismatched jack sizes in audio and video systems. The pack includes two zinc-alloy units for spare or replacement use. Builders needing a different connector arrangement or a digital interface will not be served by this passive analogue coupler.

Passive zinc-alloy construction

The coupler has no active electronics, so it draws no power and produces no heat or noise in normal use. Its brass-finished zinc-alloy body measures 34 mm long by 6 mm in diameter. The rated load is 5 VA with an insulation resistance of 5 MΩ. Users requiring signal amplification or impedance matching must look elsewhere.

Compact in-line form factor

At 34 mm x 6 mm the adapter sits inline between cables without adding bulk, freeing up space in tight equipment racks or portable kits. It requires a 3.5 mm 4-pole male source and a 2.5 mm female-terminated cable to function. Systems that use proprietary multi-pin connectors or balanced audio interfaces are not compatible with this simple two-pole converter.

Questions about this item

How do I install the 3.5mm male end into my device without damaging the connector?

Align the 3.5mm male plug with the female port and push straight in until fully seated; forcing it at an angle can bend the internal contacts.

Will the zinc alloy housing or the 5M insulation resistance degrade and need replacement over time?

The zinc alloy housing resists corrosion and the 5M insulation resistance is stable; no scheduled replacement is needed unless physical damage occurs.

What is the first limit I hit when using this adapter continuously at its 5VA rated load?

The 5VA rated load is the primary limit; sustained use above that level can cause overheating or signal loss.
