AdderView DDX30 Review
The Adder AdderView DDX30 is a true matrix KVM switch supporting up to 23 computers and 29 users, letting any user station access any connected computer at once.
This is a genuinely different category from a desk KVM: the DDX30 is a real crosspoint matrix, so it's not about one person switching between machines but up to 29 separate user stations each independently accessing any of 23 computers, the kind of many-to-many access control a trading floor or a broadcast master control room actually needs. Nothing else in this catalog does true matrix switching at this scale; the closest comparison, the Adder CCS-MV4228, is a multi-viewer for compositing sources rather than a matrix for routing access.
True Many-to-Many Matrix Access
Any of up to 29 user stations can independently switch to any of up to 23 connected computers, with no dependency between what one station is viewing and what another is doing.
Software-Managed at Scale
Configuration and access rights across dozens of stations and computers are managed centrally, rather than relying on physical button presses at each desk.
Comparison to Alternatives
Versus the Adder CCS-MV4228, that's an 8-port multi-viewer compositing sources into one display, worth it for simultaneous viewing rather than independent per-user routing. Versus the AdderView PRO AV4PRO, that's a single-user cascade switch topping out at 8 computers, a much smaller scale than this matrix.
Our verdict
Reviewed by Burooj Alam. Rated by us, not by users.
Expert rating9 / 10
A serious enterprise matrix KVM for many-user, many-computer environments, not a fit for a single desk.
Best for
- Trading floors and broadcast control rooms needing many-to-many access
- IT teams managing dozens of servers across many independent operator stations
- Facilities requiring centrally managed, software-defined KVM access control
Not for
- Single-desk or small-office users (massive overkill and cost)
- Anyone needing HDMI/DisplayPort rather than DVI video
- Simple 2-4 computer switching tasks
