Small format, big connectivity

The LS-4 is a small-footprint line selector allowing you to connect a stereo source and send it to up to three other devices. The same source signal can even be sent to all four destinations simultaneously, or any combination thereof. It’s a fantastic, inexpensive option for passive monitor switching, headphone distribution, parallel effects routing, and more. Its 100% passive design imparts zero tone color on your signal. A flexible ground lift is available internally per channel.

Multi-purpose toolbox

While small and simple, the LS-4 has limitless practical and creative potential, including but not limited to:

• Passive monitor switching with subwoofer toggle: Connect three pairs of studio monitors to Outputs A, B, and C, and connect your subwoofer to Output D.
• Headphone distribution: Connect the headphone Output of your interface to the LS-4’s Input, and connect all LS-4 Outputs to your headphone amps.
• Audition effects chains: Run a dry signal into the LS-4 Inputs, and connect different effects processors to Outputs A-D. Connect your processor Outputs to your audio interface Inputs — press buttons A-D to audition different effects processors on your signal.
• Parallel effects routing: Connect your hardware as described above — this configuration also allows you to record all four parallel processed signals in your DAW simultaneously!

We can’t wait to see what other uses you think up for the LS-4!

Built Black Lion tough

We didn’t let its compact size affect the build quality. Like all BLA products, the LS-4 is built road-tough: a steel enclosure with an anodized black aluminum faceplate. High-quality ¼” connections ensure maximum conductivity and secure connections.
