| Tech Showcase - November 19, 2013 | HDBaseT Extenders
With Bennett Liles
One of the more significant developments in AV during the past three years has been the introduction of HDBaseT. Overcoming the previous distance limitations with TMDS (Transition Minimized Differential Signaling)-based conveyance such as HDMI would have been enough to make news, but the 5Play feature carrying uncompressed video, multichannel sound, control signals, Ethernet, and up to 100W of DC power on a single Cat-5e/6 cable for up to 300ft. has assured its market success. Evidence of this impact is reflected in its wide adoption and the flood of products that have emerged using HDBaseT technology. Projectors, monitors, switchers, and extenders have incorporated HDBaseT conveyance and more are on the way. More » |

In its broad wake, Shure introduced an automixing version of the SCM800, known as the SCM810. And more recently, the SCM820 has been announced, with substantial and sophisticated updates. I was charmed to see that the front panel of the latest revision is clearly recognizable as a descendent of the original SCM800—but behind the panel lurks a vastly more powerful suite of tools that go far beyond blending eight inputs into a single output signal. Powerful automixing conventions are standard and Dante digital audio networking is available—the protocol that has appeared in so many products recently that it appears to have been adopted as a standard, or so it seems. The four versions of the SCM820 comprise the four possible permutations considering Euroblock or DB-25 analog I/O options and the option to include built-in Dante networking. An aftermarket Dante upgrade for analog-only SCM820s is available, as well. I evaluated a unit with Euroblock I/O and no Dante capabilities. More » |
