Signal processors, in their many varieties, are a critical part of any professional audio setup. They do a lot of the heavy lifting when it comes to shaping the sound of a recording, so having reliable, high-quality units is a must. Fortunately, that's exactly what Radial Engineering strives to do with their signal processors. Here you'll find a good range of devices that you can count on to deliver the features you need for your home or professional recording studio. Radial Engineering's specialty is the "direct box," or DI unit. That's the category that most of these signal processors fall into, and each one is designed to excel at a particular role - so it's important to consider your needs when picking one out. Usually, you'll use a direct box to connect your line-level audio output from instruments and other primary audio sources to low-impedance devices like mic preamps or mixing consoles. Figuring out which DI unit is right for you will depend mostly on what you're looking to connect together.
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.
