2-Channel 3.5mm Audio Mixer

The senhilear mixer blends two stereo sources into one output for headphones or speakers. Independent volume knobs let you balance levels without software. USB power means no wall adapter is needed. It suits desktop users who want simple hardware mixing between a PC, phone or laptop.

Aluminium shell with 3.5mm jacks

An anodised aluminium enclosure measures 33 x 28 x 13 mm, so it sits discreetly on a desk or in a bag. Four 3.5mm female sockets handle two inputs and one output plus headphone monitoring. Plug-and-play operation requires no driver installation. The package includes two audio cables and a USB power cable.

Passive mixing, no microphone power

This unit mixes line-level signals only and cannot supply phantom or plugin power for microphones. Buyers needing mic pre-amplification or additional input channels should look elsewhere. Ultra-low current draw allows continuous operation from any standard USB port.

Questions about this item

What does the 3.5mm stereo jack interface limit in practice?

The 3.5mm stereo jacks carry line-level signals only; the unit does not supply microphone power, so dynamic or condenser mics needing phantom or plug-in power will not work.

What physical space is needed to mount the 33mm x 28mm x 13mm aluminium shell?

The mixer measures 33 mm wide, 28 mm deep and 13 mm high, so it fits in any gap larger than those dimensions and can be tucked behind a monitor or inside a cable tray.

How is the mixer installed and which step is often missed?

Connect each source to an input jack, plug headphones or speakers into the output, then insert the USB cable into any 5 V port for power; the step people skip is confirming the USB port is live before assuming the mixer is faulty.
