Blustream RX70CS 4K HDBaseT Receiver With ARC and Audio Breakout

Blustream RX70CS 4K HDBaseT Receiver

The Blustream RX70CS 4K HDBaseT receiver connects a remote display to compatible transmission equipment over one CAT cable. It supports 1080p video up to 70m or 4K at 60Hz with 4:4:4 chroma up to 40m, alongside bidirectional control, audio breakout and compatible Audio Return Channel (ARC) operation.

Use this HDMI receiver for remote display installations that require video, audio and equipment control at the viewing location. Automatic 4K-to-1080p downscaling helps integrate a Full HD display into a compatible distribution system. Simultaneous optical and analog stereo outputs provide local audio connections, while infrared and RS-232 pass-through support control between locations. The slim enclosure and included mounting brackets suit installed AV projects with limited equipment space.

Color Space Conversion (CSC) enables support for HDMI 2.0 signals rated up to 18Gbps, including High Dynamic Range (HDR) content. Advanced functions depend on the connected transmitter or matrix, so installers should confirm compatibility before specifying the system. Bidirectional Power over Cable (PoC) supports flexible power arrangements with compatible hardware. The analog output requires two-channel PCM audio, while the HDMI connection passes supported multichannel bitstreams.
