Why Combining Best in Class Components Is Better than Using All-In-One Conferencing Products, Especially in Classrooms

This entry was posted in Lecture Recording on by .

There are quite a few all-in-one conferencing products on the market now. Their appeal is apparently If one based on the fact that they are easy to set up. Most combine an array mic, camera and speakers, while others add a built-in computer to provide connection to Zoom, Teams, etc. (rather than connect via a laptop).

The most important task of a conferencing system is providing good sound quality and pickup range.

Most of these all-in-ones have limited microphone pickup range and are useful only in small rooms. Adding auxiliary microphones can be difficult.

There are a few all-in-ones now that have better array microphones and can pick up from 30 feet. But they are relatively expensive.

If you choose to combine best in class components, you can use the Voice Tracker III auto-scanning array microphone, which also picks up from 30 feet, but which costs less than $500.

Video performance is equally important. There is constant improvement in camera technology, most notably the auto tracking cameras. For example, take a look at the 1 Beyond camera offered by Crestron. These cameras automatically focus on and zoom into the active speaker (much like auto-scanning array microphones). This makes the meeting more comfortable for the far end participant.

With all-in-one products, the camera is usually in the front of the room, limiting views of anyone presenting at the whiteboard (and the writing on the whiteboard itself). Auto tracking cameras can be placed separately from the microphone/camera/speaker, perhaps in the rear, to show (and zoom into) the whiteboard.

Clearly, loudspeakers that are larger than those in all-in-ones perform better.

The advantages of combining best in class components is especially strong for hybrid classroom applications.

Classrooms/lecture halls are usually larger, and benefit greatly from combining several microphones and cameras for better coverage.

Additional Voice Tracker array microphones can be placed on sidewalls, the backwall or ceiling to improve the pickup of questions from the class as well as the professor as he moves around. It’s easy to combine their audio with a simple mixer. It’s cost effective when several inexpensive (but high performance) microphones are involved.

Ditto for loudspeakers.

Combining several Auto Tracking cameras also has great advantages in classrooms.

One can zoom into the student asking questions while another tracks the teacher or whiteboard. The images can be shown on split screen.

Reliability is also a factor. Squeezing microphone/camera/speakers into one small box can create reliability issues. Camera, microphone, and speaker companies can optimize for reliability. For example, the failure rate of the Voice Tracker array mics have been less than 1% over the last 20 years.

Finally, there is the question of set up convenience. All-in-ones will undoubtedly be easier to set up. But combining components isn’t that hard. The Voice Tracker simply connects to a computer sound card through a 3.5mm audio jack. Or it can bypass the soundcard with a USB adapter. It can be connected to Mixers and DSP through XLR adapters. There are no controls on the Voice Tracker, its processes are all automatic.

Auto Tracking cameras have limited controls.

Finally, combining components adds flexibility. Components can be rearranged, or added as new technology arrives, and existing speakers etc. can be used.

Combining 4 Voice Tracker III Array mics for hybrid learning in a large auditorium

This entry was posted in Array Microphones on by .

Considering the success we had using Voice Tracker III array microphones in our classrooms for hybrid learning, we decided to install 4 Voice Trackers to cover a large auditorium.

Brindley Auditorium is a trapezoid shape, approximately 1,680 ft2 room with 151 seats. See the attached photos and layout.

In May 2021, the University of Mary Hardin-Baylor modernized the A/V technology in the auditorium, which includes the following:

  • Video – An 86” interactive display, two 75” secondary TVs, two 85” TVs for content replication and a 70” confidence TV.
  • Audio – Four Acoustic Magic Voice Tracker III, one on each wall. A RDLRU-MX4L 4-channel mixer to aggregate audio feeds and an AudioSource AMP100VS amplifier with six C2G 2’x2’ ceiling speakers.

See the attached block diagram.

The four Acoustic Magic Voice Tracker III microphones are able to capture audio from any seat at any location for video conferencing and distance learning.

Using the Voice Tracker I array microphone in patient rooms to enhance video conferencing

This entry was posted in Array Microphones on by .

A Hospital in Texas wanted a microphone that could do a good job picking up all the talkers in a patient’s room, but needed a cost effective product because of the large number of rooms.

They found the solution in the Voice Tracker I array microphone.

The Voice Tracker allows patients to video-conference to family and loved ones, as well as communicate clearly with doctors and nurses that are not in the room.

In the picture below, you can see the Voice Tracker I, alongside a USB camera, at the top of the footwall TV system. Both are facing the patient’s bed.

The hospital staff tested the VT I in the rooms and had about a dozen folks try it. The decision was unanimous – everyone preferred the VT 1’s sound quality. They went live with it in August 2015 when they opened their new hospital. They originally got 400 Voice Tracker Is and added an additional 350 units this year to finish up the rooms

“We just needed a cost-effective solution to resolve the audio issue and that’s where the VT 1 came in”

Connecting Voice Tracker Array Microphones to Computers with TRRS Jacks

This entry was posted in Array Microphones on by .

Some computers now have a single TRRS 3.5mm jack which combines mic input with speaker output instead of the tradition two jack approach (one jack for mic input and the other for speaker output).

The traditional jacks are TRS.

The Voice Tracker array mics have TRS 3.5mm stereo connectors.

In order to connect to a computer with a single TRRS jack, a TRS to TRRS adapter is required.

A better approach might be to use a 3.5mm TRS to USB adapter like our part 102B.

The sound quality thru USB may be better than the sound quality of the computer’s internal sound card.

Both the TRS to TRRS and TRS to USB adapters are reasonably priced

Connecting Multiple Voice Trackers Using a Mixer

This entry was posted in Array Microphones on by .

Two Voice Trackers can be combined using a simple 3.5mm stereo Y. Our 25 foot 3.5mm extension cables can be used to separate the microphones.

For better coverage in large rooms, several Voice Tracker I and Voice Tracker III can be combined with a mixer.

Mixers that accept unbalanced, mic level stereo input through a 3.5mm TRS connection would be preferred for simplicity, even if simple adapters are required.

However, most Pro AV mixers require balanced XLR connections. In that case, you can adapt from 3.5mm to XLR using an adapter/transformer like the Sescom SES-AUD-RCA-XLR adapter. You will need a 1/8th inch to ¼ inch adapter. These adapters will also help prevent ground loops. You can adapt just before the mixer, but adapting at the microphone and using XLR extension cables provides better shielding from noise pickup.

Reasonably priced mixers that have worked well with our microphones are the Shure SCM 268, the Extron MVC 121 Plus and the RDL-RU-MX4

Nova Southeastern University used the Extron MCV 121 Plus in dozens of rooms. See: https://www.acousticmagic.com/about-us/user-comments/#alinzels

Mixers can improve sound quality though features like EQ, compression limiters, etc.

An interesting example of 4 Voice Tracker III combined to cover a large auditorium (including a block diagram) can be seen at https://www.acousticmagic.com/news/combining-4-voice-tracker-iii-array-mics-for-hybrid-learning-in-a-large-auditorium/

A more expensive approach is to use a DSP device like the BiAmp Tesira.. See: https://www.acousticmagic.com/news/combining-two-voice-tracker-greater-room-coverage/

This approach is best implemented by a professional AV integrator. Care must be taken in the connections.

If you are trying to connect to a mixer or DSP using wires rather than connectors, connect the tip and the ring to Positive and Negative on the DSP or mixer.

Do not connect the ground to the DSP.
