Adapter cable Omnitronic 3.5mm to 2×3.5mm, 1.5 m, black

Omnitronic 3.5mm to 2×3.5mm adapter cable, 1.5 m, black splits a single 3.5 mm audio output into two 3.5 mm connections. The cable is intended for use with headphones, portable players, laptops, mixers and speakers to share audio or route one signal to two destinations. With a 1.5 m length and flexible black jacket, the adapter provides a simple wired solution for short-distance audio splitting without active electronics.

Advantages

The Omnitronic adapter cable offers compact passive splitting that requires no power, preserving the original signal path for common consumer audio devices. Its 1.5 m length gives moderate reach for desktop or portable setups while keeping connections tidy. The cable’s straightforward design ensures plug-and-play compatibility with standard 3.5 mm stereo jacks and avoids the need to replug devices when routing audio to two outputs.

Suitable for

• Sharing music from a phone, tablet or laptop to two pairs of headphones
• Sending one line-level output to two speaker inputs or amplifiers (when device levels match)
• Connecting a portable audio source to a mixer while also monitoring on headphones
• Splitting audio for simple stereo/mono routing in rehearsal or casual listening scenarios

Key specifications

• Connector A: 3.5 mm male jack (single)
• Connector B: 2 × 3.5 mm male plugs (dual)
• Cable length: 1.5 m
• Cable color: black
• Cable type: passive audio splitter, unamplified
• Compatible with: standard 3.5 mm stereo and many mono outputs

How to use

Insert the single 3.5 mm jack into the audio output of your source device (phone, laptop, tablet or audio player). Plug the two 3.5 mm plugs into the intended destination devices such as headphones, speakers or inputs on a mixer. Ensure source volume and destination input levels are set appropriately before playback to avoid sudden loud signals. This adapter passes the source signal passively; it does not provide level control or impedance matching, so check compatibility with connected equipment.

Usage recommendations

Use this passive splitter for casual listening and simple routing where impedance and signal level differences are minimal. Avoid relying on it for professional studio tasks that require balanced splitting, amplification, or impedance matching. For critical applications, use a dedicated distribution amplifier or active splitter to preserve signal integrity.
