Dual 3.5mm Mixer for Line-Level Sources

This active stereo mixer combines two 3.5mm line-level inputs into a single 3.5mm output for headphones or powered speakers. It suits anyone who wants to hear a PC and a phone, tablet, MP3 player or Echo Dot at the same time without swapping cables. The unit is not designed for microphone signals.

USB-C Power Eliminates Ground-Loop Hum

The mixer draws 5 V over a modern USB-C port from any charger, power bank or hub. Using a dedicated USB power adapter instead of a computer port keeps the background quiet during long sessions. Active circuitry prevents volume drop so the combined signal stays strong for hours of continuous playback.

Nano-Tape Mounting and Included Cables

Two 3.5mm audio cables and traceless nano-tape ship in the box for immediate plug-and-play setup. Stick the 3.93 x 2.75 x 0.66 inch chassis under a desk, behind a monitor or on a cabinet side for an invisible install. The only common issue is attempting to connect a microphone directly, which the line-level inputs do not support.

Questions about this item

Does the mixer generate audible noise or heat when left powered from its USB-C port all day?

The unit draws only 5 V from USB-C and contains no fan; its active circuitry stays cool and silent during continuous desktop use.

What cables or sources must I already have to connect two devices to the MAXVC670?

You need two stereo 3.5 mm line-level sources such as a PC, phone, tablet or console; the box already includes two 3.5 mm cables for the inputs.

Will the gold-plated 3.5 mm jacks work reliably with older portable players that have worn sockets?

Gold plating resists corrosion and maintains low-resistance contact, so older 3.5 mm outputs stay compatible without signal degradation.
