01AUDIO SPEAKERS
Dual source mixing for shared listening
A compact black unit sits quietly on the desk, ready to unify separate audio streams into a single, cohesive stream. Its metal casing suggests durability, while the layout invites connection rather than clutter.
This device takes two distinct sound sources and blends them, allowing two listeners to share the same experience through individual headphones or amplifiers. It suits those who value clean signal routing and simultaneous access.
02SIGNAL PATH
Precision amplification in two stages
The circuitry relies on specific components for clarity. The first stage uses an NJM4580 operational amplifier, while the second stage driver is an NJM4556A high-current unit. This arrangement ensures that when two inputs are active, they combine smoothly without one overpowering the other, maintaining fidelity throughout the distribution process.
04POWER & BUILD
External power for consistent performance
Housed in a black metal enclosure, the unit requires external power via DC voltage ranging from 5 to 20 volts. This external supply helps maintain stable operation regardless of the load on the outputs. The package contains only the stereo mixer itself, keeping the setup minimal and focused on audio function.
AT A GLANCE
The key points
- Two independent 3.5mm inputs mix seamlessly without interference
- Dual 3.5mm outputs drive headphones or amplifiers simultaneously
- NJM4580 and NJM4556A operational amplifiers handle the signal path
- Black metal housing with external DC power from 5 to 20 volts
About this product
All sockets is stereo 3.5mm, input one way, both 2 ways output is same.And input two at the same time, then output be the mixed sound. Two inputs can input two different sound sources at the same time, and plug in at the same time not affect each other. The output is also, You can connect two headphones or two amplifiers at the same time. The first stage OP AMP is NJM4580, and the second stage driver is NJM4556A high-current operational Working voltage:DC 5-20V Colour:black Material:Metal Package Contents: 1 x Stereo Mixer Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
