Radial Engineering Signal Processors
Some of Radial's other signal processors have more specialized uses. Take the SGI TX/RX Studio Guitar Interface for example. These boxes are long-distance guitar signal carriers, allowing you to send your instrument's tone to an amp as far away as 350 feet. That means you have total freedom to compartmentalize a studio, or even to improve your tone onstage by lowering the monitor amp volume and routing the signal to a second offstage amp.
Of course, sometimes you might want to drive a whole stack of amplifiers from a single instrument. For that, you can use the Radial Engineering JD7 Injector Guitar Signal Distribution System. This rack-mounted box duplicates its input across as many as seven outputs, giving you a ton of versatility to split up your signal for driving multiple amps or mixers at once or even just to give yourself a quick way to switch from one amp to another on the fly.
Whenever you need to connect two different components together, there's a decent chance you'll need a direct box to help them ""talk"" to each other. Or maybe it's one of the more specialized signal processors that you're looking for. Either way, Radial Engineering is a great choice, with a solid reputation for quality backing up every unit that they ship.
