Radial EngineeringProD8 Eight Channel Rackmount DI
1/4
Independent shopping perspective
The Korena take
Eight-channel rackmount DI for stages and studios that need every keyboard, playback rig and line source converted to balanced XLR in one rack space.
Strong match
Who this is for
- Keyboard rigs sending many stereo pairs to front of house
- Studios patching lots of line gear to a console
- Playback and backline sources feeding a stage snake
Consider the trade-offs
When to look elsewhere
- Players needing one or two channels — pay for a single DI instead
- Rigs with no rack to mount it in
- Budget-constrained setups where per-channel cost matters
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
Ground lift per channel
You isolate the one hum-prone source without breaking the ground on the other seven.
Detail 03
180-degree phase switch per channel
Flips polarity on a single channel to fix cancellation when a source arrives out of phase with the rest.
Detail 04
Parallel 1/4 inch A and B inputs
Two front-panel inputs per channel, so you can feed a channel from either of two sources.
Detail 05
1/4 inch thru jack
Passes the source signal on to your stage amp while the XLR feeds the console.
Detail 06
TRS insert jack per channel
Drop a compressor or EQ into a single channel's path without rewiring the whole rack.
Final check
Know before you order
- 01Rack rails required — this is not a floor unit
- 02No XLR or 1/4 inch cables included; budget for sixteen-plus runs
- 03Front-panel inputs mean cables run out the front of your rack
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Can I use it for a stereo keyboard rig?
Yes. Each stereo instrument uses two of the eight channels, so eight channels covers four stereo sources.
02What is the thru jack for?
It passes the unaltered signal to a stage amp or monitor while the XLR output feeds the mixing console.
03When would I use the phase switch?
When a channel sounds thin or cancels against another mic or DI source. Flipping polarity on that one channel restores the low end.
04Does it fit a standard rack?
Yes, it is built for standard rackmounting. Check your rack depth against the unit before ordering.
