WHAT’S QUANTUM LITE

I.1 Introduction

Picture 1. Quantum Lite codec.

Quantum Lite is a new-generation handheld reporter codec that inherits world­class IP technology from Prodys Ikusnet Video Codec Family and ProntoNet
Audio Codec Family.

Lightweight and handy this product will fill the application gap between multi­user 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

Among 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:

 Double 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 Area 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

BRAVE protocol. This protocol enables using and combining any IP connection
(two UMTS /LTE, Wi-Fi and LAN) for an extremely reliable audio contribution.

 Control and monitoring: A 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.

 The <Menu> icon accesses to the configuration parameters if required.

 The <Monitor> icon accesses the status information for the current

communication if desired.

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 Area 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 & UDP 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 LAN1. 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 APN 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 APN 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 APN for each modem.

Picture 11: Mixed colours indicate you might proceed with your audio

communication restricted to the blue capacities.

II.3.3 Address BOOK

Either you just have the same destination to call (i.e. one QLST at your studio),
or several possible destinations are available, you might prefer keeping the
numbers to dial ready in your Quantum Lite internal agenda or address BOOK.

The recording of addresses in the address book is done through the Book Entry
menu. To get there follow

Menu >Book >New

Prodys S.L. Tel: [phone] Θ Fax: [phone] Θ Email: [email protected] Θ Web: www.prodys.com

Page 13

Picture 12: A new book entry

The <address> field must be the public IP address for the destination codec.
Usually you prefer <Low Delay> profile for your voice communication. Anyhow
you might select another profile at calling time.

II.4 Dial-in your studio

After all those initial settings, which likely remain the same for years, you are
able to start you first communication to the studio.

1. Press the big green button to dial. (Please refer to picture 4)

2. Choose your BOOK destination to dial or type manually the address.

Picture 13: Dial-in from your BOOK list

Page 14

Picture 14: Dial-in typing the destination address

3. Now your communication is progressing. You should get confirmation with
a big red button as picture 5.

Remark: Unsuccessful dial attempts would indicate “unable to connect”. The big
green button offers you another attempt. This result might indicate either your
studio codec is busy, you dialled a wrong destination or the “port forwarding” at
your studio internet router is incorrect.

Picture 15: Unable to connect. Remote is busy or wrong address.

Remark: About the best suitable call profile, please refer to section IV.1
(“Profiles”) for more details.

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.
