WHAT’S QUANTUM LITE
I.1 Introduction
Picture 1. Quantum Lite codec.
Quantum Lite is a new-generation handheld reporter codec that inherits world-
class IP technology from Prodys Ikusnet Video Codec Family and ProntoNet
udio Codec Family.
Lightweight and handy this product will fill the application gap between multi-
user and mixing commentary codecs and the best-effort smartphone app.
This unit can be controlled from its built-in web graphical interface, its front
panel display menu, or from ProdysControlPlus application.

I.2 Quantum Lite Features
mong Quantum Lite most remarkable features are:
Compression algorithms: Quantum Lite is equipped with the best of low
delay compression algorithms from voice frequencies encoding until full
20kHz bandwidth: OPUS and Enhanced apt-X
Communications:
ouble UMTS /LTE internal modems. The SIM card slots (micro
SIM) are located on the sides of the device.
Ethernet interface. The codec might use Local rea Networks with
direct access to the internet for the communication.
Wi-Fi interface is supported by means of an external Wi-Fi modem
connected to the USB slot on the head side.
Streaming protocol: The streaming protocol is the highly performing
BR VE protocol. This protocol enables using and combining any IP connection
(two UMTS /LTE, Wi-Fi and L N) for an extremely reliable audio contribution.
Control and monitoring: large touch screen provides the management
options, making usage quite simple for any user. It is also possible to control
the unit remotely with ProdysControlPlus application as long as the unit is
connected to the Internet, and even when the unit is connected to the
Internet behind a firewall.

Remark: You might skip one menu back or go directly to the main menu from
any deeper menu level with following controls, located in the upper left side of
any menu window.
II.3 Some facts before you might proceed using your handheld codec
Some settings must be provided for the handheld codec and its companion QLST
at your studio before any communication is possible. If these preparations
already took place, please refer to the next section.
II.3.1 Installing the QLST at the studio site
The QLST device must be connected to your Local rea Network and the access
for external TCP/UDP ports must be granted. Please request at your company IT
department assignation for your public IP address router (Port Forwarding at
your Internet router) for port 53000 TCP & U P service.
Remark: Please notice if several QLST devices are going to be used behind the
same Internet router, each QLST should get a different port assignment. Small
offsets would let addressing each QLST individually. E.g. first QLSTport 53000,
second QLSTport 53010, third QLSTport 53020, etc.
In QLST the factory default Ethernet port to be used is labeled L N1. For any
other arrangement please check document “QLST Hardware and Reference
Manual”.

II.3.2 UMTS /LTE settings for the handheld codec
Quantum Lite must get the SIM cards inserted and identify the local UMTS /LTE
service provider as any cell phone would require. Service Provider identification
should be an automated internal process taking less than 10 seconds. However
the automated identification might be disturbed, finishing unsuccessfully. You
might realize this disturbance if any of the small dots keeps on blinking red for
more than 10s.
Remark: Please advice the SIM card slots accept micro sized SIM cards only
Picture 6: Internal modems registering to UMTS /LTE network
In this case you might assist manually the codec for a successful Service Provider
identification. Please type manually your local PN for the SIM cards 1 and 2.
Following procedure is required:
1. Go to Menu>Conf>Interfaces>3G/4G
2. Choose internal modem 1 or 2
3. Provide the correct PN of this Service Provider as the example of pictures
7 and 8. If you are using two different Service Providers for SIM card 1
and 2, please remind using the proper PN for each modem.

RECALLING PRESETS & CALL WITH PROFILES
With your Quantum Lite you will included a choice of equipment configuration
ready to use. Those got the name <Preset>
Please press this sequence to access to the preset menu: Menu > Preset
The default list of presets might be enhanced or modified by you or your
company codec administrator for the sake of supporting your most common
applications for Quantum Lite.
The current firmware version does not offer any factory default profile.
IV.1 Profiles
The <Profiles> instead lead to some temporally configuration changes the user
will apply only for the next call only. Once the call finished, the codec recovers its
original configuration. Therefore <Profiles> is useful for a quick adjustment of
the audio delay (jitter buffer) for the handheld and the studio codecs, or for
switching quickly the compression algorithm (therefore the audio quality) just at
the moment the destination is dialled.
Remark: Using any profile from the handheld device, this selection is applied
synchronously to the handheld as well to studio unit automatically.
