Introducing a compact yet incredibly versatile line selector, the Black Lion Audio LS-4 opens up a world of routing possibilities for your studio setup. The LS-4 features two inputs that allow you to distribute a stereo source signal to up to four separate outputs simultaneously—or any combination thereof. Whether you need passive monitor switching, headphone distribution, parallel effects routing or a way to audition different effects chains, this road-ready unit has you covered.

Ultimate Connectivity for Passive Monitor Switching

With the LS-4, you can effortlessly switch between up to three pairs of studio monitors at the press of a button. Connect your main monitors to Output A, secondary monitors to Output B and a subwoofer to Output D for seamless toggling between configurations. This passive switcher ensures your signal path remains pristine, with zero loss in audio quality.

Streamline Headphone Distribution

Distributing your audio interface's headphone output to multiple stations is a breeze. Simply connect the interface output to the LS-4's input, then route the individual outputs to your headphone amps. With its compact footprint, the LS-4 makes an ideal headphone hub for small project studios or classroom settings.

Audition Effects in Real Time Without Patching

The LS-4 lets you effortlessly audition different effects processors on your dry signal without constant re-patching. Run your dry signal into the inputs, then connect each output to a separate effects unit. Switch between the outputs to instantly hear your tone processed through different chains—perfect for quickly comparing settings or finding the perfect combination.

Flexible Routing for Parallel Processing and More

This unit's versatile routing capabilities extend far beyond simple switching. With its two inputs and eight outputs, the LS-4 allows for parallel signal routing to multiple destinations. Connect different processors to each output, then record all four processed signals simultaneously in your DAW for creative blending. Its 100% passive design, high-quality 1/4" jacks and flexible ground lift ensure pristine signal integrity throughout.
