Rapco Horizon is a brand that's probably best-known for their high-end cables. But where you'll find cables, you'll also find signal processors. These devices will help you out with the connectivity you need to get those cables hooked up, and they do it with the same great reputation that goes for all of Rapco Horizon's pro audio gear. One of the building blocks of a recording studio is the direct box. These units allow you to get high and low-impedance audio sources and devices to talk to each other, and that's just the beginning of what they can do. Check out the DBBLOX boxes if high-to-low or low-to-high is all you need, or if you want a unit that does even more, take a look at the Rapco Horizon STL-1 Stereo Line Direct Box, which gives you plenty of options for how to handle the signals going through it.
Rapco Horizon's other in-line signal processors do a lot to help you control your audio signal. For example, if you want to tame those peaks, the PADBLOX comes in 10, 20, 30 and 50 dB attenuation levels. Maybe you'd just like to control your mic volume on the fly without having to fiddle with your audio rack? In that case, the CVPBLOX is the unit for you.
Sometimes it can be hard to figure out what's going on when your system just won't perform the way it's supposed to. In situations like this, one of the first things you should rule out is the possibility of a damaged cable. This is where the Rapco Horizon HCT-LD Cable Detective comes in. It couldn't be any easier to use: just plug in the cable and check whether the unit lights up: a quick way to save yourself from maintenance headaches that turn out to have been cable problems all along.
A signal processor doesn't have to be a complicated thing, and Rapco Horizon proves that with a series of devices that are built to do a specific job, and do it well. From interconnection to attenuation and even cable diagnosis, there is plenty you can do with Rapco Horizon signal processors in your pro audio setup.
