INTRODUCTION
V-Quantum is a powerful portable IP audio codec, but enabled to play out
H.264 video @BRAVE protocol, providing an enriched working commentary unit
for reporters. Therefore this device simplifies the voice-over commentaries to
video media.
BRAVE protocol supports several IP links between the codecs assuring a highly
reliable audio and video connection with the master control room.
3x mic/line mono inputs +1 line/International Sound input + 1 Stereo USB
input/output) are available to be mixed, encoded and streamed in Stereo mode.
Additionally the device provides digital video output for the H.264/BRAVE video
stream display.
Several application scenarios might be possible with V-Quantum:

Apart from the possibility of using three streams for different communications, it
is still possible to use the rest of the system resources. This has been summarize

port with 2 inputs and 2 outputs. The auxiliary data can be
sent/received along with the audio for remote control/signalling.
Control and monitoring: The unit can be configured from its touch
panel and from its embedded web server. The device is fully
configurable via remote web browser. Support from the MCR for
outside news teams is possible using ProdysControlPlus3product;
as long as the unit is connected to the Internet, and even when the
unit is connected to the internet behind a firewall .
Small and lightweight: Dimensions are width 270mm, height 85mm
and depth 235mm. Weight is about 2.6Kg ( without battery ).
I.5 The set of Manuals
The Quantum Family User Manual is applicable to most of the common features
provided by the Quantum Family of codecs.
For some specific features or restrictions, the user is referred to the proper
Hardware and Reference Manual applicable to the codec in use. Installation
requirements, physical and electrical parameters are also included in this
document.
3ProdysControlPlus is a software management product. For more details about please contact
[e-mail]

If several different Quantum Family codecs are managed by means of the
ProdysControlPlus application please refer to the ProdysControlPlus Manual as
well.
Prodys IP codecs provide the user with a control protocol which allows the user
to develop customized management software. The control interface for this
protocol is either the RS232 serial port or the Ethernet port. For detailed
description please refer to the Quantum Family codec SDK User’s Manual.
I.6 Application Notes

II.1 Input audio path overview
Any input audio (e.g. XLR or USB audio) follows its processing path under User
adjustments or PRESET selection4.
Each input audio path (IN1..IN3, USB L, USB R) terminates at either the PGM,
TB1, TB25or TECH bus. The PGM and the TB1 busses feed the PGM and
Talkback encoders6respectively prior upstreaming.
II.2 Gain controls for audio inputs
At the left hand side pressing the <MUTE> button will silence all audio inputs
for the uplink as well as for the headphone and local XLR audience.
4For details on PRESET configuration please refer to the QUANTUM USER MANUAL § IV.3
5TB2 & TECH busses are not available for BRAVE or SIP protocol, but for AES67 /DANTE
application since firmware version 3.0.
6SIP protocol does not enable an independent “Talkback encoder”, but the operation of the TB1
switch can route this audio path into the L or R channel of a stereo upstreaming signal.

Each input is individually enabled with its <ON> button.
Any gain change gets a pop-up indication as this example
The audio level control can be made locally or remotely by using the V-Quantum
web interface.
Remote input gain control might be possible getting into Menu /Audio /Gain
Level:

Page 15
II.2.1 Sensitivity of the audio gain knobs
It is possible to adjust sensitivity of the gain knobs for the audio inputs as well as
for the headphone knobs at Menu /Audio /Misc ( Resolution dBs/Turn ).
II.3 Headphone controls
In order to prevent pain due excessive sound pressure on the
ears it is strongly advised to handle with care the headphone level
configuration.

Prodys S.L. Tel: [phone] Fax: [phone] Email: [e-mail] Web: www.prodys.com
Page 16
It is safe to manage any new streaming connection or new signal
matrix with the headphone off the head, but around the neck.
Adjust with gentle turns the correct sound level for each
headphone (left and right side).
Once the average sound level is set, the user might use the
headphones in a safe way.
II.3.1 Headphone volume control
Those are the headphone gain controls. Any headphone gain change gets a pop-
up with the dB indication. A green LED indicates that following trims affect only
this headphone output ( please to the picture above ).
II.3.2 Headphone sound mix control

Prodys S.L. Tel: [phone] Fax: [phone] Email: [e-mail] Web: www.prodys.com
Page 17
It is possible to change the audio assigned to each of the 5 audio sources for any
headphone output. Just clicking on the name of the source, on top of the knob
icon, the following window will appear:
Upon the HP selection, (just pressing once or
trimming the HP knobs 1 .. 3), the user gets access
to the Headphone Sound Mix for his feedback using
the right hand group of knobs labelled HP MATRIX.
Each signal might be enhanced or dimmed trimming
the knobs. Furthermore pressing once the HP Matrix
knob, disable or enable the partial signal immediately
from this headphone mix.
Please remind the HP MATRIX does not affect the
encoded signal up or downstream.

Page 18
In the Select Signal window, all the audio signals managed inside the codec are
available to be used as a headphone output.
II.3.3 Headphone preferences
Adjustment and balance of each headphone may be set in three different flavors.
These three flavors can be selected are set [Menu /Audio /Outputs ..]:
Independent Stereo control
Independent Mono control (L & R)
Panoramic control (Tx /Rx balance)
II.3.3.1. Headphone L/R independent mono set up
With the so-called Independent mono level control the headphone audio level
can be adjusted independently for each ear. This mode is especially useful when
L and R signals on the headphones are not related (binaural monitoring).
Pressing several times the HP gain knob, the user might trim the global L+R, L
or R headphone.

Page 19
II.3.3.2. Headphone independent stereo set up
This control mode works in a similar way to the independent mono control, but
keeping the left and right channels of the audio sources always coupled.
II.3.3.3. Headphone panoramic set up
This control is preferred by users uncomfortable with binaural monitoring; such
prefer hearing the same audio composition on the left and right ear.

Prodys S.L. Tel: [phone] Fax: [phone] Email: [e-mail] Web: www.prodys.com

This mode is allows enhancing either the local (Tx) or the far-end (Rx)
encoded sound on the headphones.
II.4 Analogue audio input arrangements
In the front panel there are two types of connectors: Jack connectors for the
headphone outputs (3), and XLR connectors for analogue inputs (4):
