The (IR) system shall be
transmitted to a receiving device as defined in 2.01 B
and D
The 2.4/5.0 GHz
frequency shall be transmitted to personal smart
devices such as cellular phones and tablets through a
free application as defined in 2.01 C and E
The system shall be
capable of connecting to a Dante network via an
external audio interface adapter (POE required)

a micro USB connector used for programming/setup,
inventory control, charging and firmware upgrades
The receiver shall
incorporate automatic battery charging circuitry and
use a non-proprietary lithium ion battery
The receiver shall
automatically turn on when removed from the charging
device and automatically turn off when returned to the
charging device
The receiver shall have
additional charging contacts to allow for multiple
charging options
The receiver shall have
a signal-to-noise ratio of 60 dB or greater, THD less
than 2 percent and shall have an audio frequency
response of 63 Hz – 15 kHz (+/-3 dB)
The Wi-Fi receiver shall
be personal smart devices such as cellular phones and
tablets as provided by the users
The audio over Wi-Fi
shall be delivered to the personal smart device via a
free application downloaded onto the personal device
When the free
application is launched, the personal smart device
will automatically connect to the audio over Wi-Fi
server
The application will
list the available channels and play the audio when
selected by the user
The free application
shall also be capable of containing user documentation
and instructions in addition to ads, promotional
banners and videos
The app shall be
customizable, allowing the venue to load in its color
pallet and logos
