Chowmain - Blustream PLA88CS Matrix driver (FREE)

Recommended Posts



Chowmain releases FREE manufacturer sponsored Blustream PLA88CS driver for Control4. The PLA88CS is a 4K HDMI 2.0 8x8 Matrix, distributing HDMI, ARC, LAN, Bi-directional IR / RS-232 and PoC up to lengths of 150m (1080p) over a single CAT cable. Advanced optional features include dual HDMI and HDBaseT™ outputs featuring CSC for support of 4K resolutions including 4K 60Hz 4:4:4 colour space, and HDR, with independent down-scaling of 4K video to allow those displays only capable of supporting lower video resolutions to receive 4K video while still showing maximum original UHD resolution on the higher-definition displays.

The PLA88CS includes independent audio routing, Audio Return Channel (ARC), Optical (S/PDIF) audio delay for lip sync correction, bi-directional IR and RS-232 pass-through, and a web-GUI for control and configuration.

The Matrix also provides advanced features including independent Dolby Audio (Atmos) & DTS Audio down mixing on HDMI and audio outputs allowing a mixture of different audio output formats for use with different audio capable displays and AV amplifiers.

On top of routing of audio and video signals Control4 integration also provides dedicated source and display drivers for CEC based control.
