II.2 Control Panel
II.2.1 Level controls for MIC/LINE inputs
Each audio input can be adjusted independently. There are two possibilities of
gain control activation: control by click and control by movement. The mode
selection in done in ‘Audio->Misc’ menu.

Prodys S.L. Tel: [phone] Fax: [phone] Email: [e-mail] Web: www.prodys.com
Page 11
II.2.1.1. Activation by click
In this option the MIC level controls are locked to prevent from unwanted
changes. To unlock a gain control, press the button in the middle and the current
level gain will be displayed on the screen. In addition, the central button will be
illuminated by a blue LED to indicate that the control is unlocked.
Press once and move gently the rotary control and turn it counter clockwise or
clockwise to decrease or increase the input gain.
This level control will be locked again automatically after 3 seconds of no
intervention, or after pressing again the mid button. Then, the round led will be
turned off.
II.2.1.2. Activation by movement
Aiming a more intuitive and quick operation for reporters /commentators now
Quantum W codecs provides the new “activation by movement” mode for input
gain controls.
Just moving any of the round input gain controls (IN1, IN2, IN3) with a slight
touch, the display will lead directly to following pop-up menu:

Prodys S.L. Tel: [phone] Fax: [phone] Email: [e-mail] Web: www.prodys.com
Page 12
-4,5 dB
-40 dB +15 dB
+2 dB
Mic 1 Line 3Mic 2
-10 dB-4,5 dB
Mic 1
A simple touch in the round control will unlock the control.
In the example above the pop-up menu addresses the gain control for the first
input.
Pressing subsequently any of the “gear icons”, the commentary can quickly
check and modify the mic or line setting of this input.

II.2.1.3. Remote gain control
The audio level can be controlled also remotely by using the web interface. Once
the audio input gain setting has been selected to be controlled by remote
control, the Quantum W reminds this effect on its touch panel upon any attempt
to increase or decrease the audio gains locally by means of the audio control
knobs, with the message “Gain controls are remotely controlled”.
To control the audio input gain from the web interface, click on the ‘Menu-
>Audio->Gain levels->Inputs’ and select ‘Remote’, as in the picture below:
For more information about the technical specifications for the audio inputs,
please refer to Chapter V.1.1.
II.2.2 Headphone level control

Prodys S.L. Tel: [phone] Fax: [phone] Email: [e-mail] Web: www.prodys.com
Page 14
In order to prevent pain due excessive sound pressure on the
ears it is strongly advised to handle with care the headphone level
configuration.
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.
Audio inputs and outputs are managed in a similar way. Each audio output can
be adjusted independently. There are two possibilities of gain control activation:
control by click and control by movement. The mode selection in done in ‘Audio-
>Misc’ menu.
II.2.2.1. Activation by click
In this option the headphone level controls are locked to prevent from unwanted
changes. To unlock a gain control, press the button in the middle and the current
level gain will be displayed on the screen. In addition, the central button will be
illuminated by a blue LED to indicate that the control is unlocked.

Press once and move gently the rotary control and turn it counter clockwise or
clockwise to decrease or increase the input gain.
This level control will be locked again automatically after 3 seconds of no
intervention, or after pressing again the mid button. Then, the round led will be
turned off.
II.2.2.2. Activation by movement
Aiming a more intuitive and quick operation for reporters /commentators now
Quantum W codecs provides the new “activation by movement” mode for output
gain controls.
Just moving any of the round gain controls (HP1, HP2, HP3) with a slight touch,
the display will lead directly to following pop-up menu and the control will be
unlocked:
When the button in the center of the gain control is pressed, the following
window will appear on the display:

Prodys S.L. Tel: [phone] Fax: [phone] Email: [e-mail] Web: www.prodys.com
Page 16
When this window is active, the six round buttons are active and each one
controls the headphone mix (in the example above, HP1) and the five inputs that
can be added to the mix: Program (Prog), Cue (Cue), Talkback TX (Tb_Tx),
Talkback RX (TB-Rx) and International Sound (Int Snd).
When the control icon is shown in black color, it indicates that the input is
available for headphone output.
When the control icon is in red, that input is muted and, therefore, not added to
the headphone output.
The commentator can enable or disable any of the sources just pressing any of
the equivalent hardware middle buttons.
In SIP communications Talkback TX (Tb_Tx) and Talkback RX (TB-Rx) are not
available.
II.2.2.3. Independent and panoramic operation modes
There are three different operation modes for the headphone outputs. These
three modes can be selected from the web page or from the touch panel menu:

Prodys S.L. Tel: [phone] Fax: [phone] Email: [e-mail] Web: www.prodys.com
Page 17
Headphone L & R independent stereo control
With the Independent level control the headphone audio level can be adjusted
independently for each ear.
This option allows mixing directly the stereo audio sources into its correspondent
left and right channels. Just click on the cross-points of the headphone audio
matrix control to enable or disable one source audio signal on both left and right
channels.
Once the mix has been configured, use the round button to control the level of
the stereo mix. Pressing softly in the middle button of the rotary control, left
channel can be regulated. Pressing again, the gain of the right channel can be
adjusted.
This level control will be locked again automatically after 3 seconds without
touching the controls, or after pressing the button until the blue light switches
off.
Headphone L & R independent mono control
Like the Independent stereo control, the headphone audio level can be adjusted
independently for each ear. However, with this option the mixing for left and

Prodys S.L. Tel: [phone] Fax: [phone] Email: [e-mail] Web: www.prodys.com
Page 18
right channels is independent. This mode is especially useful when L and R
signals on the headphones are not related (binaural monitoring).
Headphone panoramic control (Tx /Rx balance)
This control is preferred for users uncomfortable with binaural monitoring that
prefer to hear the same audio signal on the left and right ears.
This mode is useful if the user wishes to balance the relative level between
transmission and reception signals. Firstly, the user should configure what
signals take part on the transmission group and what signals take part on the
reception. To do that, just click on the cross points at the matrix and select what
signals will be added to TX and RX parts.

Prodys S.L. Tel: [phone] Fax: [phone] Email: [e-mail] Web: www.prodys.com
Page 19
Then use the round button to adjust the gain level and press the middle
button to balance the relative level of the TX and RX audio signals.
