Infrared, Frequency/Digital Modulation, and Induction Loops

A comparison of assisted listening system technologies

By Dr. Carol Meyers

Hearing aids are remarkable. They help people with hearing loss engage in conversation with friends and family, even in crowded environments. They restore the ability to enjoy the pleasant sounds of life — birds chirping, children laughing, the everyday sounds —paper rustling, heels tapping — and the less pleasant but necessary noises —car horns beeping, sirens blaring. Hearing aids are truly modern miracles that pack very sophisticated technology and sound processing into the smallest of devices.

But sometimes hearing aids alone aren’t enough. Much like regular tires are perfectly good for cars in the warmer months but snow tires are needed to drive in challenging winter conditions, hearing aids need a boost in situations where speakers are situated far from audiences, or a play is being held in a large auditorium where ambient noise interferes with speech, like during a graduation ceremony. That’s where assistive listening technology comes into play. Hearing aid wearers aren’t usually seeking more amplification when in public venues. What they need is better speech understanding, and the ability to suppress background noises while bringing speech to the forefront.

Blackmagic Design announces ATEM Camera Control Now Available

Atem-switchersNow customers with ATEM production switchers can control their cameras via the SDI connection

Blackmagic Design today announced the immediate availability of ATEM Switchers Update 6.0 which adds support for controlling cameras from ATEM production switchers via the program feed to the camera. ATEM Switchers Update 6.0 is available now free of charge from the Blackmagic Design website.

Until now the ability to control cameras from the live production switcher was only available to extremely high end broadcasters who had the costly infrastructure that allowed this feature. With the new ATEM Camera Control software update, ATEM live production switchers can now control cameras via a new open standard protocol sent to the camera via the return program feed.

ATEM Camera Control is compatible with the new Blackmagic Studio Camera when running software update v1.8.2 or later. The Blackmagic Studio Camera HD and Blackmagic Studio Camera 4K models feature both optical fiber and regular SDI program return feeds to the camera and the commands from the switcher are broadcast to all cameras via this program return feed.

Educational Training at Church Media U

Church Media UChurch Media U is a one-day seminar for HoW media volunteers and pro’s that tours the country helping to equip churches to understand and use their visual media technology better.

Changes in projection technology, lighting and content development have created a huge opportunity that the HoW have only just begun to tap. It is more affordable than ever to literally transform a room into a truly sacred-feeling place as we lift eyes, voices and hearts in worship to God. It is also easier than ever to create a lot of visual noise that distracts from the purpose of ministry.
Church Media U wants to help you embrace the one and avoid the other.

The two questions they hear most are these: What equipment hardware and software does our church need now? And/or: Now that we’ve got all of this awesome equipment, what in the world should we do with it?
