A Guide to Wireless Video Conferencing Audio
Chris Harding – Business Development Manager
Yamaha Wireless Adecia is a unified communications/video conferencing audio solution that utilizes tabletop wireless gooseneck/boundary microphones, a PoE-powered dedicated Dante WAP, and a charging station. The solution is perfect for rooms and venues where running cables is not practical.
The Wireless Adecia range is an extension of the existing Adecia products which include a processor, network switches, ceiling mics, and PoE Powered Line Array Speakers. Wireless Adecia operates with battery-powered microphones that transmit wirelessly to a WAP (wireless access point), the WAP converts those mic channels into Dante for transmission through a network switch and into a VC processor. The charger acts not only as a charger but a bridge for easy setup, pairing, and firmware upgrades.
RM-CR Processor
To best utilize the features of Adecia, an RM-CR processor is a must. This is the interface to bridge the audio channels from the microphones into your PC as well as return the far-end audio from your meeting participants to the PoE speakers. The RM-CR is a simple USB A 2.0 connection to your PC. It has easy-to-use room calibration that sends sweeps and chirps to measure the room and apply the best acoustic and echo cancelling processing settings required for professional and intelligible VC.
How to Wireless Adecia
When incorporating the Wireless Adecia into an RM-CR it is a two-step process.
- STEP 1 = The WAP
- Set up the WAP, the wireless mics, and the charger through the WAP’s web interface. You can use the RM Device Finder to quickly find the IP of each device. Once all mics are connected and firmware updated you are ready to join the WAP to the RM-CR.
- STEP 2 = The Processor
- Join the WAP to the RM-CR Processor and run the room calibration.
RM-WAP-8 and RM-WAP-16 Access Points and RM-WCH-8 charger
The WAP comes in two models. The RM-WAP-8 for 8x wireless mics & the RM-WAP-16 for 16x wireless mics. The WAPs are designed to live in the same room as the microphones for the best coverage and signal strength. The WAPs are PoE-powered devices like the processor and speakers, enabling a simple single cable connection back to a network switch. The charger only requires power and a tidy spot for housing and charging the mics when not in use.
The WAP is your central point of communication for pairing the microphones with the RM-WCH-8 charger. The fastest way to pair is to dock all your microphones into the charger and then push the pairing button on the charger as well as on the WAPs web GUI. Once paired you can easily update firmware and assign audio channels.
You continue to follow the steps of the WAPs setup guide walkthrough which essentially pairs the mics to the WAP and assigns Dante channels to each mic. Then, all audio is ready to be transmitted via Dante into the RM-CR processor and into your computer via USB.
Onto Step 2
Now you will need to log in to the RM-CR Web GUI and set that device up with the VXL PoE powered Line array speakers and the WAP. It too has a simple step-by-step run-through where you assign each device to the processor, which is essentially just auto-assigning and subscribing Dante channel behind the scenes. This is where the RM-CR does its room sweeps and calibrates the mics and speakers to be in perfect working order, programmed with settings matched to reflect the room’s acoustics.
System IO is as follows. The WAP is the input device, the processor is the brains, the PoE network switch connects it all together with the VXL speakers as outputs and the battery charger as an extension of the wireless system. Simple and easy to deploy and manage. Check out our post on Netgear AV Line to see how simple networked AV is to manage.
Real World Features
Some really cool features on the WAP include a DECT scan function to identify and clear the way for available wireless channels to be assigned.
As the technology is based on DECT it runs on the 1.9GHz spectrum which is free from other open and unlicenced bands like 2.4GHz commonly found in WiFi, Bluetooth, Zigbee, and the like.
There were 100s of channels available in the scan I ran on setup. You will have no issues clearing the way for 8 or 16 channels of wireless.
