Description

StarTech MU12MF Speaker Extension Audio Cable

Overview

The StarTech MU12MF is a 12-foot (3.7m) audio extension cable designed to extend the reach of your 3.5mm audio sources, such as microphones or speakers, to a device. This cable specifically routes the left audio channel from a male 3.5mm mini-jack connector to a female 3.5mm mini-jack connector, ensuring signal integrity for stereo or mono audio applications where precise channel separation is required. It's ideal for scenarios where your audio source is positioned away from the recording or playback equipment, such as extending a microphone to a camera or a speaker to a sound system in a fixed installation.

Compatibility

This cable is compatible with any audio device utilizing a standard 3.5mm mini-jack connection. It is specifically designed for use with systems requiring a male 3.5mm input and a female 3.5mm output for the left audio channel. This includes, but is not limited to, extending audio feeds for surveillance cameras, computers, portable media players, and powered speakers that use a 3.5mm audio interface.

Installation Notes

The MU12MF cable features a slim profile, with a product width and height of 0.3 inches (0.8 cm), allowing for discreet routing through conduits, cable raceways, or behind panels. The cable weighs only 1.6 oz (45.5 g), minimizing strain on connected ports. Its construction is intended for stationary or low-movement applications to ensure long-term reliability.
