InfoComm 2019 showcased MXL’s continued growth in forging collaborations with cutting-edge UCC tech companies, while its latest compact USB microphone garnered new interest in telemedicine and e-learning applications.
MXL UC offers its new VC-404K dual 4K camera / AC-404 microphone solution pre-installed into Urben’s custom Mini frame along with an interactive D7 touchscreen by DTEN, to create an all-in-one huddle room solution.
The integrator was able to treat two, 36-seat board rooms and one classroom hall with ceiling-mounted AC-360-Zs for Zoom Room integrated meetings. Here’s a closer look at the install:
The new web conferencing mic built for use with Zoom video software made a big splash at the show, taking home two industry awards and generating lots of conversations from integrators and end-users about its potential.
The progression of the Audio/Video industry is fascinating. The first broadcast medium was audio only…it’s called radio and it was used primarily in the home. The first visual medium was film, and it was video only.
When they merged video with audio in film it was big. When they merged video with audio in broadcast, they called it TV, and it changed the world.
In the electronics industry, we spend a lot of time talking about video. First it was video itself. Then it was color. Then it was the VCR. Then it was SVHS. Along came High Definition, and it changed the way we treat video. 4K, 8K, 16K, and all those Ks will keep improving the picture. Who knows what else it will do? Only time will tell. (Here’s a cool infographic on the history of television.)
Video is fun. Video gets attention.
No one really talks much about audio. The technology is old, it hasn’t changed much over the years, and it just isn’t as sexy.
But without good audio, life is a silent movie.
People will accept compromised video – grainy, shaky, or low resolution. But if they can’t understand what is being said, they will turn it off.
Whether it’s web conferencing or shooting video, proper mic’ing of the subject makes all the difference in getting the message across.
Rule number 1 in audio is to get the mic as close to the speaker as you can.
Rule number 2 is to keep the mic out of the picture as much as possible.
Rule number 1 and rule number 2 are in direct conflict with each other. What’s a poor audio engineer to do?
That is where the compromise comes in. Use a microphone that picks up the audio, while keeping it out of the picture or in an inconspicuous place. How does one achieve this objective? Pick the best microphone for the situation.
Audio In Web Conferencing
The standard practice in web conferencing seems to be a low resolution web cam with a built-in pinhole mic sitting on top of a monitor hung on the wall. Basically, that means the closest speaker is about 6 feet away from the mic and the farthest is 15 to 20 ft. away. With a low quality mic that far away from the subject, the sound will not be very good. Add to that room acoustics, people talking over each other, and paper shuffling during the meeting, and the result is a web conference that is seen and not heard.
MXL offers various audio solutions that are affordable and bring the sound closer to the subject.
A USB Boundary Microphone is the easiest way to get good sound, without a big mic sticking up in the picture. It will pick up an area of about 25 feet, 180 degrees. In most small conference rooms, that is all that is needed. Place it on the conference table, and the sounds “bounce” off the table and gets gathered up in the mic. There’s no obvious microphone in the camera view so you’re achieving the seemingly conflicting goals of close mic’ing and discreet mic’ing.
USB Gooseneck Microphones are a bit more intrusive but can be placed closer to the person speaking. This is a good solution for a small meeting of four or five people. The MXL AC-400 gooseneck can be used with up to four AC-40EXT extension mics. They look very professional and do not call attention to themselves, and they deliver the sound quality you need.
These microphones will meet the web conferencing needs of most small to medium sized businesses.
Once you get past these options, things get a bit more complicated. In some cases, there is no way around a more complex and expensive solution, especially when the room is larger and there are many more people in the meeting. In that case, a combination of table mics, ceiling mics, and a DSP is probably needed.
Our goal at MXL is to provide low cost, simple, high quality solutions for web conferencing. One thing that has made this possible is the introduction of software programs such as Microsoft Lync, Bluejeans Network, and Vidyo, to name a few. All of these programs have echo canceling built into their systems, eliminating the need for an expensive echo canceling solution built into the mic.
What makes web conferencing so popular is the low cost and simplicity that the digital age has created. It can be done with nothing more than a computer, TV, camera, microphone, and broadband connection. Check out my post on video for web conferencing.
Because of the affordability, small companies are now adding web conferencing systems to their offices. Large companies are expanding them out to all of the conference rooms and offices, instead of just one main room.
In short, if you are in the process of adding web conferencing to your office, remember that your conference is only as good as the sound. Make sure to move that microphone off of the top of the monitor and down closer to the people.
Look for two new boundary web conferencing microphones coming very soon from MXL!
