Detail 01
Interface box, not a USB device
It works off the headphone jack, so no drivers, no USB, and any device with an output works.

Rapco HorizonLTIBLOX Laptop Interface
Independent shopping perspective
The Korena take
A passive DI-style box that takes a laptop or phone headphone output and sends it to a mixer or PA on balanced XLR. For playback into a sound system.
Strong match
Who this is for
- Running backing tracks from a laptop into a live PA
- DJ or presenter feeding house sound from a phone
- House-of-worship playback from a computer at FOH
Consider the trade-offs
When to look elsewhere
- Recording into a computer — this feeds audio out, not in
- Players wanting a guitar or mic preamp
- Anyone needing volume control at the box
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
Balanced XLR output
Long cable runs to the mixer stay quiet, unlike a consumer 1/8 inch cable stretched across a stage.
Detail 03
Stereo source to mixer
You feed the mixer two console channels and pan them, rather than one summed line.
Detail 04
$89 price
Sits at the low end of stage playback boxes, so it goes in the gig bag as a permanent utility item.
Final check
Know before you order
- 01You still need XLR cables to reach the mixer — none included
- 02Set playback volume on the laptop; the box has no level knob
- 03Disable system alert sounds before the show or they hit the PA
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I record into my laptop with this?
No. It sends audio from the laptop out to a mixer or PA. Recording into the computer needs a separate audio interface with inputs.
02Will it work with a phone or tablet?
Yes, anything with a standard headphone output. Newer phones without a headphone jack need the manufacturer's adapter first.
03Do I need power or batteries?
No. It works off the signal from your device, so there is nothing to charge or plug in.
04How many mixer channels does it use?
Two, one per side, so you can pan them hard left and right for proper stereo playback.
