ADENA Hack: How to use RADA Duo microphones with AREC and other devices?

The RADA DUO is a wireless microphone system comprising two transmitters and one receiver. Both transmitters can operate simultaneously using UHF radio frequencies and maintain effectiveness at distances of up to 50 metres from the receiver. One of DUO's distinctive features is its compatibility with various devices. DUO sets include standard 3.5mm TRRS and TRS cables, a 3.5mm to USB Type-C cable, a USB Type-C to Type-A adapter, a 3.5mm to 6.5mm adapter, and additional accessories like a phone mount, making DUO sets easy to set up in any scenario.

There are several ways to use DUO with AREC Media Stations, and the choice depends entirely on the station model you possess. For instance, on stations like LS-2, LS-200, and others with 3.5mm Line inputs, you can connect DUO using the provided 3.5mm TRRS to 3.5mm TRRS cable. Simply plug it into the monitoring output of the DUO receiver on one end and the Line input of the Media Station on the other. When configuring the audio, keep in mind that you can adjust the volume level both through the DUO system and through the Media Stations. While DUO transmitters and receivers have dedicated buttons for this purpose, volume adjustment on Media Stations can be accomplished in various ways, including through the 'Administrator' web page. To access it, navigate to 'Media I/O' -> 'Audio' subpage.

For stations without 3.5mm inputs, you can use the USB cable instead. Connect the 3.5mm TRRS to USB Type-C cable to the receiver's "monitoring" output, attach the USB Type-C to Type-A adapter, and then connect it to any of your AREC station's USB ports. On most models (e.g., LS-300), DUO will be automatically recognized when connected in this manner. However, on others, such as LS-860, you may need to select it from the list of audio devices first.

To connect DUO to other devices, refer to the datasheet or user manual of the device to determine the appropriate cable. Typically, you'll need a 3.5mm TRRS to 3.5mm TRS cable for DSLR cameras, USB Type-A or Type-C for computers, a 3.5mm to 6.5mm adapter for musical instruments and amplifiers, and the 3.5mm TRRS to 3.5mm TRRS cable for all other standard connections where a stereo signal is used.

Case Study: How AREC Devices Helped Team Danmark Stream High-Quality Webinars.

Dear ADENA Partners, our latest case study features Team Danmark, a government-supported sport organisation. Thanks to the work of our distributor UNIT.DK and system integrator AV Center, the organisation created a streaming studio with AREC devices to share knowledge about their work and initiatives with the wider world.

Team Danmark is a government-funded sport organisation that was created to support Danish athletes in every way possible. For example, it assists with talent development, coordination of academic studies and sport careers, and researching the latest trends and implementing them practically for the benefit of athletes. Some of these activities are carried out online through streamed webinars, which require time, effort, and most importantly, third-party operators to set up. To ensure that the organisation can stream whenever it desires, and can easily produce high-quality videos on their own, Team Danmark requested our partners to design a professional, yet simple-to-use streaming studio.

UNIT and AV Center experts did just that, and installed an AREC LS-860 Media Station. The 4-channel model allows Team Danmark to record and stream up to 4 video sources in Full HD@60fps to two streaming platforms simultaneously, over-achieving the quality requirements of the organisation. The station serves as a central unit to which every other AV device in the room is connected. Multiple PTZ cameras, Sennheiser ceiling microphone system, and a computer running Teams conferencing software for bringing in remote participants are all mixed together with the organisation’s logos and backgrounds by the LS-860 and presented in customisable layouts. This combined audio and video output is returned to Teams as a webcam using the RADA HDMI to USB Bridge, giving the Teams attendees and streaming platform audience the same viewing experience.

What makes this setup easy to use is how well AREC integrates with various control options. In Team Danmark’s case, all the key functions that their employees require are displayed on a small touch tablet from a control system. Through a simple click, they can control the cameras’ PTZ positions, recording and streaming layouts, graphics, audio, and more. This means that the presenters can effectively manage the whole recording and streaming process themselves and fully focus on their tasks without a cameraman.

With their new streaming studio, Team Danmark is now able to deliver higher-quality webinars at will. Are you working on similar requests? Let us know at www.a-dena.com and we will be happy to discuss your project requirements.

ADENA Hack: How to choose between AREC Media Stations?

There are currently 8 Media Station models in the LS/KL series. All of these devices share core features, such as recording, streaming, automatic backup, calendar scheduling, video layout, overlay, background controls and more. But there are certain differences that can help you choose the right model for your needs. We’ve previously covered some of these unique differences in the ADENA Hack №54, and so this time we are diving deeper into the topic.

To begin with, we can divide the Media Stations into three categories - 2, 3, and 4 video

channel models. By channels here we mean the maximum simultaneous number of video sources that a Media Station can work with. 2 channel models are LS-US2(N), LS-110, LS-2, and LS-200, 3 channel models are LS-300 and KL-3T, whereas 4 channel models are LS-400 and LS-860(N). Within these categories, these models are different from each other in terms of their AV inputs and outputs, as well as certain unique features.

For example, we’ve highlighted the unique feature of LS-110 in ADENA Hack №33. LS-US2’s unique feature is its ability to work with USB video inputs and also an optional NDI-HX licence. LS-2 and LS-200 are both rack-mounted stations, with the LS-2 being a more budget model. As for the 3 channel models, KL-3T is defined by its inbuilt touchscreen, which makes it perfect for placements on lecterns, podiums, and mobile usage. Lastly, in the 4 channel category, LS-860 is defined by its multiple HDMI and 3.5mm line/mic inputs, optional NDI-HX licence, and inclusion of a specially integrated accessory called ARECast.

Precise differences between the Media Station models can be examined via our comparison table.
