How this source-based order is set
Positions #1-#7 retain two discrete output channels ahead of the summed-mono alternatives at #8-#9 and the active four-channel DI/line-mixer at #10. Within #1-#2, the basic two-passive-channel group uses neutral source-domain then model-name order: radialeng.com JDI Stereo, then ProD2. Within #3-#5, the additional-routing or multi-section group uses the same neutral source-domain then model-name order: radialeng.com JDI Duplex, then whirlwindusa.com DIRECT2, then pcDIQ. Within #6-#7, the remaining two-discrete-output group uses the retained official product-type label alphabetically: DB24 is a stereo direct interface before DJdi is a two-channel passive DI box. #8-#9 are summed-mono products in neutral source-domain then model-name order: rolls.com DB14b, then whirlwindusa.com podDI. #10 is DI4 because its retained source describes an active four-channel DI and line-mixer with AC supply. This is a documented topology-and-label order, not a stock, sound-quality, or hands-on performance ranking.

Keep source limits in the buying decision
A pad, ground lift, isolation, or power statement does not prove it will solve a particular hum, level, phantom-power, or compatibility issue. [25] [30] [35] [44]
How we compared.
Source-based desk research used current official manufacturer product pages or manuals for exact product models. Ranking prioritizes documented channel count, input and output connectors, pad or isolation controls, and any retained power detail. It does not measure sound quality, durability, availability, price, real-world reliability, or hands-on use.
