coverage PLUS expanded audio coverage to everyone with a
Smartphone or tablet |
| Features |
|
Extended Audio Reach
Easy and Convenient
Free Smartphone App
The IR system shall be
transmitted to a receiving device as defined below
The audio over Wi-Fi
shall be delivered to the personal smart device via a
free application downloaded onto the personal device
The assistive listening
system shall be capable of broadcasting audio over
both Infrared (IR) and 2.4/5.0 GHz Wi-Fi frequencies,
allowing users to receive the audio through a
receiving device with ear speaker/headphones or
directly to Bluetooth enabled hearing aids
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 below
The Infrared
Transmitter/Radiator Combo shall be capable of
broadcasting up to two audio channels with the choice
of four mono carrier frequencies, 2.3, 2.8, 3.3, and
3.8 MHz
Channel carrier
selections shall be set via a back panel rotary
switches
The Transmitter/Radiator
coverage area shall be up to 30,000 ft2 with single
channel transmission when using the LR-4200-IR
The device shall have a
timer that shuts off the carriers after 15 minutes
when no audio is present at the inputs
The device shall have
two independent mixing audio inputs, one for each
transmission channel

earphones or the integrated neck loop based upon which
is connected
The receiver shall have
two 3.5 mm (TRRS) connectors to drive the integrated
neck loop lanyard or up to two mono or stereo
earphones
The receiver shall
incorporate a multi-functional display (OLED) that
indicates battery status, inventory number, volume
level and a customizable channel name
The receiver shall
employ a unique iDSPTM noise reduction technology
The receiver shall be
fully programmable via PC software
The receiver shall have
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
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
