2-in/8-out Line Selector
Black Lion Audio - LS-4

Small format, big connectivityThe Black Lion Audio LS-4 is a small-footprint line selector that allows 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. It’s a fantastic, inexpensive option for passive monitor switching, headphone distribution, parallel effects routing, and more. Its 100% passive design imparts zero tone colour on your signal. A flexible ground lift is available internally per channel. Its compact size doesn't compromise 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.
