Detail 01

Radial EngineeringProAV1 Single-Channel Direct Box
1/5
Independent shopping perspective
The Korena take
A single-channel direct box from Radial for converting one unbalanced source to a balanced XLR feed. Aimed at AV and installed-sound work.
Strong match
Who this is for
- Sending a laptop or media player output to a mixer across a long run
- Fixed AV installs where one source needs a permanent mixer feed
- Podium or conference rooms feeding a house console
Consider the trade-offs
When to look elsewhere
- Stereo sources — one channel handles one signal only
- Players who want tone shaping, since a DI passes signal, not colors it
- Anyone already running balanced XLR or TRS outputs from their source
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
Direct box function
Turns a high-impedance unbalanced signal into balanced low-impedance, so cable runs of 50 feet or more stay quiet.
Detail 03
XLR output
Plugs straight into a mixer or stage snake mic input rather than a line input.
Detail 04
AV-oriented design
Built for install and presentation use, where the box gets set once and left alone.
Detail 05
Radial build
These live under podiums and in road cases. Expect it to survive being stepped on.
Final check
Know before you order
- 01Stereo sources need two boxes, or a two-channel DI instead
- 02Check whether your source uses 1/8-inch, RCA or 1/4-inch and cable accordingly
- 03The XLR out goes to a mic input, not a line input
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I use this for a stereo laptop?
Only if you sum to mono or buy a second one. This is a single channel, so it handles one signal at a time.
02Do I need phantom power?
Feed it phantom from the mixer if your source is passive-unfriendly. Check the manual for your specific hookup, since requirements depend on the source.
03What's it for versus just running a long cable?
An unbalanced cable picks up hum and loses high end over distance. The DI balances the signal so a long run stays clean.
04Will it change my tone?
It isn't a tone device. Its job is to get the signal to the console intact over distance.
