Monoprice 139670 Blackbird 4K 8x8 HDBaseT Matrix video switch

8x8 HDBaseT Matrix for 4K distribution

The Monoprice Blackbird 139670 is an 8x8 HDBaseT matrix switch designed to route eight HDMI sources to eight independent zones. It delivers 4K video at 60 Hz with YCbCr 4:4:4 colour sampling and HDR support. Seven HDBaseT outputs and seven included receivers extend signals over single Cat5e or Cat6 cables. A local HDMI output provides a nearby monitoring point with extracted digital optical and balanced analogue audio.

Installers needing long runs and multi-zone audio

This unit suits integrators who must distribute 4K sources up to 40 metres and 1080p sources up to 70 metres without signal degradation. The 24 V Power over Cable feature powers the remote receivers directly from the matrix, reducing the need for local power outlets. Four digital optical S/PDIF outputs allow extracted audio to feed separate sound systems. Buyers who require more than eight input or output ports should consider a larger chassis.

40-metre 4K reach over Cat5e/6

The decisive specification is the 40-metre transmission distance for 4K@60Hz 4:4:4 signals over a single Cat5e or Cat6 cable. If the installation demands longer 4K runs, this matrix will not meet the requirement. For shorter distances or 1080p-only distribution the headroom is generous, but the 40-metre 4K limit determines whether this model fits the project.
