Rapco HorizonSTL-1 Stereo Line Direct Box
Independent shopping perspective
The Korena take
Two-channel line-level direct box for sending stereo sources to a mixer or snake over balanced XLR. For keyboard, playback and backline rigs.
Strong match
Who this is for
- Keyboard players feeding a house console in stereo
- Playback rigs sending a laptop or interface to FOH
- Stage setups where the mixer is a long cable run away
Consider the trade-offs
When to look elsewhere
- Players needing a single mono channel and nothing more
- High-impedance passive guitar or bass pickups
- Anyone wanting onboard preamp gain or tone shaping
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Line level input
Built for the output of keyboards, mixers and playback devices, not for raw instrument pickups.
Detail 03
Direct box function
Converts unbalanced high-impedance signal to balanced low-impedance, so long runs to the console stay quiet.
Detail 04
Balanced XLR output
Plugs straight into a stage box or snake channel like a microphone, no adapter needed.
Detail 05
Under $100 for two channels
Cheaper per channel than buying two boxes, at the cost of not being able to place channels separately.
Final check
Know before you order
- 01No cables included — you need two inputs and two XLR runs
- 02Confirm your source is line level, not instrument level
- 03You get two console channels used, not one, for a stereo feed
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I use this with a keyboard?
Yes. That is the main use. Take the keyboard's left and right line outputs into the box, then run XLR to the mixer or stage snake.
02Do I need one box or two?
One. It handles both sides of a stereo source in a single unit, which is the reason to pick it over a mono direct box.
03Will this work for electric guitar?
It is built for line-level sources. A guitar pickup is a different signal level and impedance, so an instrument direct box is the better match.
04Does it need power?
Check the unit before your first show and plan for either phantom power from the console or a supply, since one is not included in the box.
