![]() ![]() That said, some devices have multiple frequency ranges available, so you’ll need to check with the manufacturer. This is usually in the form of a sticker on the back of receiver. An infrequent audio dropout may not be a major concern for minor sound reenforcement in small settings, but for larger events, it can be a true show stopper (I know this from personal experience).Īll wireless microphone systems are required to list their frequency rang on the device. So, you may start noticing that your trusty old wireless mic isn’t so trusty anymore, and that could happen overnight. WAIT… keep reading! I know what you’re thinking, “So, plenty of time to ignore this…” The “gotcha” is, these new mobile phones will start showing up this fall, and the carriers are already testing devices on the 600MHz spectrum. The hard deadline to stop using mics on the 600MHz spectrum is 2020. So, what does this mean for me? Well, it’s time to decommission those wireless mics using the 600 MHz band (or at least start budgeting for new wireless mics in the short term). ![]() The 600 MHz band, where many wireless mic systems on campus operate, was auctioned off in March 2017 and is to be used for mobile devices (phones) starting later this year. ![]() The Backstory: Way back in the olden days of 2012, Congress authorized the FCC to auction off some of the “old analog TV” wireless spectrum that was killed off in 2009. The 600 MHz spectrum (technically 614 – 698 MHz) is about to get considerably more congested with wireless interference in the coming months and years. It may be time to retire those trusty old wireless microphone systems that you’re currently using in your classrooms and auditoriums. We’ll be keeping our eye on this device as it enters the market. Add in WireCast (or OBS if you are on an ultra tight budget), and you could start hosting some rather high quality streaming events (alumni engagement session, “behind the scenes” when high profile guests that come to campus, live Q&A with the admissions folks, etc.) on the cheap-ish. ![]() That said, one interesting feature of this device is that you could theoretically use two Cam Links (one for video and one for content) connected to a laptop (with two USB3 core hubs) and create an ultra portable live teaching rig, assuming you had all the other necessary equipment (camera or video capable dlsr, mics, lights, etc.). While it mentions 60fps, does it also capture 24, 25, 30 and 50? Also, no word on if or how or if it will handle interlaced video. That said, some key details are missing from the website, specifically, what resolution and frame rate does the HDMI inputs accept. The website is somewhat thin on details, but after digging around a bit it seems the Cam Link uses the UVC driver, so it should be compatible with most modern versions of Windows, Mac, and Linux without the need for a driver. While we haven’t had an opportunity to test the device, it looks to further lower the barrier of entry for higher quality video streaming and capture. Enter Elgato and their $130 HDMI to USB converter. Osprey and Magewell both have very compelling offerings with enhanced features, but at a price of roughly $300 – $330. When it comes to converting an HDMI signal to something a little more computer friendly (USB), there are plenty of good options. ![]()
