Hey, this is Andrew with zZounds, and here are some things to know about the Radial EXTC Stereo Reamp Box.

A reamp box lets you take a pre-recorded line-level signal from your audio interface and convert it to an instrument-level signal, which you can then send out to effects pedals, guitar amplifiers, or really anywhere you want to send audio.

Starting at the back, you've got two combination XLR/quarter-inch inputs, quarter-inch outputs, and XLR outputs. On the front is where you'll find all the features that really make this stand out compared to the average passive mono reamp box. You've got a pair of quarter-inch inserts, which is where you're sending and receiving signal. These two knobs here are your level controls for the send and return. This helps ensure that you're not overloading your pedals with a signal that's too hot, and it also lets you adjust the signal on its way back in as you run it through effects.

There are a ton of different ways you can use this. If we're just looking at the core goal of the reamp box—sending a signal out to your amplifier—and you're not necessarily even using stereo functionality at this point, you would just take a single output from your audio interface into the input, which would then come out of the send and go into your amplifier.

Aside from the send and return jacks, you've got a bypass switch for the effects loop—just an instant bypass with an LED indicator that lets you know when it’s switched on or off. Your… read more blend control lets you blend from fully wet to fully dry. And with that, you also have a phase flip switch. So if you're getting any kind of weirdness between the dry signal and the wet signal, you can hit the phase flip to correct it.

You can also use this with software amplifiers. If you want to use effects pedals with a DI signal—running into the effects pedals, back into here, and straight back into the computer—you have different effects routing options. You can run two completely independent effects chains if you want—two mono effects chains. Adjusting your gain staging across multiple pedals or anything like that, you'll always know where your signal is coming out. Having that level control is really handy if you need to dial things back a little so you're not clipping on the way back into an interface.

I hope this information was helpful if you're in the market for a reamp box and looking for something with a few extra bells and whistles, plus a ton of flexibility and utility. The Radial EXTC is a great option, and it's available at zZounds.com. read less
