Wi-Fi/RF Advanced System (Dante)
|
| Overview |
| This advanced
combo Wi-Fi/RF Advanced System known as LCS-121-01-D from
Listen Technologies comes with Dante Assistive Listening
capability. Combining Wi-Fi and RF technologies to give
compliant audio coverage this assistive listening system
is capable of broadcasting audio over both the 72 MHz
frequency and 2.4/5.0 GHz Wi-Fi frequencies. This will
allow users to receive the audio through a receiving
device with ear speaker/headphones or directly to
Bluetooth enabled hearing aids PLUS expanded coverage to
everyone with a Smartphone. The Wi-Fi System comes with an
external audio interface adapter for Dante multi-channel
digital media networking capabilities |
