Adder AVX4016 Review
Adder AVX4016 16-port 4-user CATx VGA matrix KVM switch
The multi-user upgrade of the AVX1016, letting four administrators simultaneously and independently access any of sixteen CATx-extended servers.
Four Administrators, Sixteen Servers
Larger IT teams often need more than one person accessing the server room's KVM matrix at once; the AVX4016 supports four simultaneous, independent users across the same sixteen-server capacity as the AVX1016.
Comparison to Alternatives
Against the single-user AVX1016, the AVX4016 costs more for genuine multi-user concurrency, justified only when multiple admins truly need simultaneous access. Against Adder's AVX5016IP, the 4016 stays local CATx rather than adding IP-based remote access.
