General specifications
PortaNet is the first really portable audio codec which provides real time audio
communications over IP networks. In addition, it comes fitted with an 1-BRI
ISDN interface, which allows ISDN connectivity at those places where IP is not
available.
PortaNet, as a member of the Prodys IP audio codec family, includes all the
features of the ProntoNet, but adds some important enhancements in the audio
interfaces and operationally for portable use.
These are the PortaNet most important features:
Analog Audio: PortaNet incorporates a mixer with four MIC/LINE
level configurable audio inputs and an extra line level input that can be
mixed to the headphone outputs to provide the international sound to
the commentators. It also includes three headphone outputs and two
line level analog balanced audio outputs. All the outputs can be
configured by the user to suit the audio signal to be carried, to adapt
to the needs of different applications.
Compression algorithms: PortaNet is equipped with the widest
range of compression algorithms without any additional cost: G711,
G722, PCM, MPEG1,2 Layer II, Mpeg 1,2 Layer III, MPEG 2,4 AAC LC,
MPEG4 AAC LD, MPEG4 AAC HE, Standard and Enhanced apt-X™.
Communications: IP and ISDN connectivity. With PortaNet it is
possible to establish two independent connections, one for program
and the other for coordination.
Power supply: Desk Top AC/DC Power Converter and an optional
battery which provides 3 hours of autonomy. The battery can be
charged on the system and its status can be monitored on the screen.
Auxiliary data: PortaNet includes a serial port (RS232) and a GPIO
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 front
panel and from its embedded web page. All the controls are
configurable remotely. The keypad can be controlled and also blocked
from the web page for security reasons.
Small and lightweight: its weight is about 2 kg. and its dimensions
are: 70 x 285 x 243 mm.

Installing the PortaNet
Before unpacking unit check its packaging for any signs of damage or
mishandling during transportation, report any damage to the shipping
company immediately. Unpack the unit carefully, if you find any damage or
the unit does not work correctly, you should contact Prodys or its distributor
as soon as possible.
III.1 PortaNet overview
PortaNet has all its connections in its front and rear panels. The keypads and
display are placed in the top surface.
III.1.1 Control Panel

PortaNet User Manual 12 of 156
Input audio control keypad.
On Key Each audio input has a key to
enable/disable it. When an audio input is
enabled, it is connected to the program
line (line 1).
Tb Key PortaNet allows the user to establish two independent
communications, using either IP or ISDN. Each input can be configured to be
sent through the program line (line 1) or through the coordination or TalkBack
line (line 2). Pressing the Tb key for one input causes this input to be mixed with
those signals assigned to the coordination or TalkBack line (line 2).
LED´s There is a led related to the status of each input:
• OFF: Input disabled.
• Green: Input enabled and connected to the program line (line 1).
• Red: Input enabled and connected to the TalkBack line (line 2).
Power LED
It shows the power supply status and also battery status.
-GREEN: The external power converter is powering the unit. The battery is
not connected.
-BLINKING ORANGE: The external power converter is powering the unit.
The battery is connected and it is being charged on the system.
-ORANGE: The external power converter is not powering the unit. The
battery is connected and powering the unit.
-BLINKING RED: The external power converter is not powering the unit.
The battery is connected and powering the unit, but it is about to run out
(about 20 minutes / 10% of battery capacity).
When the unit is starting, the Power LED will be blinking green.
PortaNet User Manual 13 of 156
III.1.2 The front panel and its connectors
In the front panel there are two areas: Audio inputs and Headphone outputs.
Because of space restrictions the Auxiliary output level control is also there.
There is an additional fourth input in the rear panel. This
input doesn’t have an associated headphone output.
MIC/LINE Audio inputs: There are four MIC/LINE audio inputs. Each audio input
includes a switch to select MIC or LINE level, and another one for selecting
whether to supply 48 volts. phantom power to the MIC.
line/mic switch:
When this switch is in the UP position, the line level input is
selected (maximum input level +20 dBu).
When this switch is in the DOWN position, this input is
configured to work as a MIC level input.
ph swtich(48 volts. Phantom powered):
When this switch is in the UP position (OFF), this option is
disabled.
When this switch is in the down position (ON), this option is
enabled.
Headphone outputs: There are three headphone outputs, each one related to
its corresponding audio input. Signals present on the headphone audio outputs
will be dependent on the configuration of the audio headphone matrix available
in the PortaNet web browser. More information about it in next chapter about
PortaNet’s input and outputs.
There are audio level controls for each output and for each ear.
Line level balanced auxiliary audio output: Along with the three headphone
outputs, there is a fourth output called ‘aux’. This audio output is totally
independent from the headphone outputs, and it is placed together with these
only for space saving reasons. This output is a balanced line level output, with a
PortaNet User Manual 14 of 156
maximum level of +20 dBu. This output is user configurable; that means that it
is possible to define which audio signals will be present in this output.
Further information about audio output configuration can
be obtained from chapter 5 - PortaNet Blocks.
III.1.3 Rear Panel
The rest of connections are located on the rear panel:
III.1.3.1 Fourth MIC/LINE audio input (in 4).
The same as the inputs from the front panel, it can be configured as LINE or MIC
level, and it has the possibility to be phantom powered (48 volts.) However, it
doesn’t have a headphone output related. For this purpose, the ‘aux’ output
might be used.
III.1.3.1.1 LINE level input (International Sound Input – Int. in)
This is an additional line level input which can be mixed with the headphone
outputs to provide the international sound to the commentators.
III.1.3.2 Second auxiliary line level output.
Called REC output, this output can carry the program line signal, the return from
the program line or the sum of both signals. This is a balanced XLR connector.
Further information about audio output configuration
can be obtained from chapter 5 - PortaNet Blocks.
PortaNet User Manual 15 of 156
III.1.3.3 Auxiliary data: GPIO and RS232 ports.
The GPIO port on a DB9 connector allows remote
control/signalling by means of remote contact closures.
There are two ground contact inputs and two relay
outputs.
Another DB9 connector at the rear panel provides an
RS232 port for sending/receiving auxiliary data along
with the encoded audio for IP and ISDN
communications.
Over ISDN, the auxiliary data and GPIO information will be only available in
those compression algorithms which support ancillary data along with the
encoded audio, and when this option is enabled.
Over ISDN, it is possible to choose between ProntoNet format and Pronto2/3
format (in which the GPIOs information cannot be sent). To be backward
compatible with ISDN Pronto2/3 Prodys devices, select Pronto2/3 format.
When selecting IP as communication interface, the auxiliary data can be sent via
a different path, different from the audio one. This method has 3 big
advantages: less delay independent from the audio codification delay; the
possibility to send/receive auxiliary data regardless of the compression mode
used for the audio communication; and the possibility to send/receive the User
bit of the AES/EBU frame. The drawback is that the audio and data delay won’t
be the same.
III.1.3.4 Ethernet port – the LAN Connector
The LAN socket is an standard 100Base-Tx (10/100 Mbps) Ethernet connection
that takes a RJ45 plug. Through this Ethernet port it is possible to transmit and
receive audio, as well as manage the equipment. Next to the socket there are
three LEDs that indicate different states for the connection and these are very
useful in problem-solving situations.
LAN LED’s:
PortaNet User Manual 16 of 156
Green LED LINK STATUS: ON = Connected
Orange LED RECEIVE STATUS: On =
Receiving Data.
Further information can be obtained in the chapter -
XIV - Connectors.
From the web interface and the front panel menu it is possible to set the speed
and duplex configuration to the following values: AUTO, 10HD, 10FD, 100HD,
100FD1.
III.1.3.5 ISDN Port
The PortaNet incorporates an ISDN terminal adapter that allows
connection to a basic rate ISDN line (2B+D). It supports different
ISDN protocols (EURO_ISDN, DMS100, AT&T 5ESS and NAT1).
There is one RJ45 connector for connecting to an S/T interface
S/T (S0).
There is available a special version with U ISDN interface.
III.1.3.6 Power supply
PortaNet comes supplied with a desk top AC/DC
converter (16 volts. output) to be connected to the
power connector located at the rear panel. The
power converter works with an AC input range of 100
to 240 VAC, 50 to 60 Hz.
The power switch is located just below the power
connector.
In addition, there is also available an optional custom
battery pack. Whenever the external power converter
is connected, the power is supplied from it, and the battery will be charged when
necessary. When the external power converter is unplugged from the unit, the
battery will take over.
1
This option is available from version 5.2.1 onwards.
PortaNet User Manual 17 of 156
The power LED on the upper panel informs about the status of the battery and
the power supply. These are the possible status for this led:
-GREEN: The external power converter is powering the unit. The battery is
not connected.
-BLINKING ORANGE: The external power converter is powering the unit.
The battery is connected and it is being charged on the system.
-ORANGE: The external power converter is not powering the unit. The
battery is connected and powering the unit.
-BLINKING RED: The external power converter is not powering the unit.
The battery is connected and powering the unit, but it is about to run out
(about 20 minutes / 10% of battery capacity).
Once the unit is switched on, the boot sequence will start. This sequence will
take about 50 seconds to finish, when the screen will display the status display.
When the unit is starting, the Power LED will be blinking green.
PortaNet User Manual 18 of 156
PortaNet audio inputs
IV.1 Location
There are four MIC/LINE level inputs, switchable between LINE and MIC level.
Three of them are located on the front panel, and the fourth one is on the rear
panel. Moreover, there is an additional line level input located on the rear panel
which can be mixed to the headphone outputs.
IV.2 Technical specifications
IV.2.1 MIC/LINE level inputs
All the MIC/LINE level inputs are transformer balanced on a XLR female
connector. These inputs are switchable between MIC and LINE levels by
means of a switch placed on the right side of the input connector.
It is possible to supply phantom power (48 volts.) to each input. There is
a switch on the left side of the input connector for this purpose.
When the audio inputs are configured as MIC level inputs, sensibility
range is –60 to –25 dBu.
When phantom power is enabled, the whole gain is decreased by 15
dB to compensate for the the higher output of condenser MICs.
Thus, the gain range will go from –45 to –10 dBu.
When the inputs are configured as LINE level inputs, the maximum input
level will be +20 dBu.
Each input level can be adjusted independently.
IV.2.2 International Sound LINE level input.
Electronically balanced on a XLR female connector.
Maximum input level is +20 dBu
PortaNet User Manual 19 of 156
IV.3 Audio Level Controls
Each audio input can be adjusted independently. The audio level control can be
made locally from the knobs or remotely by using the PortaNet web browser.
Once the audio input gain setting has been selected to be controlled by remote
control, the PortaNet reminds this effect on its display upon any attempt to
increase or decrease the audio gains locally by means of the audio control knobs.
The International Sound Input level can be adjusted only remotely.
IV.4 Audio input configuration
IV.4.1 ON keys
Each audio input has a key to enable/disable
it. When an input is enabled, it will contribute
to the audio sent through the program line
(line 1). The corresponding LED will light on
GREEN, indicating that the input is enabled
and going through the line 1.
IV.4.2 TB Keys
PortaNet supports two independent communications via IP or ISDN. Thus, we
can establish one connection for the main program, and another one for
coordination, or TalkBack program. Each input can be configured to be added to
the audio contribution on line 1 or line 2 by means of the ‘TB’ and ‘ON’ keys
located on the top surface.
When an input is connected to line 2 or TalkBack program (pressing the
Tb key) it is disconnected from the program line (line 1). The
corresponding LED will light on RED.
When an input is connected to line 1 or program (pressing the ON key)
it is disconnected from the TalkBack line (line 2). The corresponding
LED will light on GREEN.
When the input is disabled, the led is off.
PortaNet User Manual 20 of 156
When one input leaves the TalkBack line (line 2), this
input is disabled for security reasons. This way, this
input cannot enter the program line unintentionally.
However, it is possible to change this operation mode
from the web page. When the Recover Last Mode is
selected, the input will recover its previous status when
it leaves the TalkBack line.
PortaNet User Manual 21 of 156
PortaNet audio Outputs
There are three headphone outputs and two general purpose balanced audio
outputs (line level).
V.1 Location
The three headphone outputs are located together on the front panel.
One of the balanced audio outputs is located on the front panel, called
‘aux’, and the other is on the rear panel, and it is called ‘REC’.

to the program line or to the talkback line. Also, it allows the user to select
whether the signal will be controlled from the audio input keypad.
V.2.2.1 Attenuation when the MIC/LINE level input goes to Talkback or
Program
It is possible to define an automatic attenuation on signals that feed the
headphone outputs when the corresponding inputs go from Program to Talkback
or vice versa. The attenuation will be carried out according to the following
critera:
Program, Cue or International Sound can be attenuated when the corresponding
input is connected to the Talkback channel. It is possible to define an
independent attenuation level for either of them.
The same thing can be done regarding Talkback Tx and Talkback Rx, that is,
either signal can be attenuated when the corresponding input goes to program.
V.2.2.2 Enable from TB Key
“Enable from Tb Key” is an additional option that only is available for Talback Tx
and Talkback Rx. When it is enabled, the corresponding signal will be sent to the
headphone outputs only when the corresponding input has been connected to
the Talkback channel, that is when its corresponding Tb key has been pressed.

When this option is disabled, this signal will be always available on the
headphone outputs regardless of whether the corresponding input is connected
to the Talkback channel or not.
V.3 Line level balanced audio output: REC
The audio sources for the REC output can be selected from the PortaNet web
browser.
V.3.1 Technical specifications
Bandwidth 20Hz-20kHz (0.3dB).
Maximum audio level: +20dBu.
THD+N < 0.005% @ 1kHz.
SNR < 100 dB.
XLR male connector fitted to the rear panel.
In normal operation, this output carries the audio coming from the
program line (line 1). This audio signal is called CUE.
Output impedance < 50 ohms.
V.3.2 Operation Modes
The REC output supports two different configurations depending on the selected
audio sources in the auxiliary output configuration matrix of the web browser:
PortaNet User Manual 25 of 156
V.3.2.1 Codec Mode
In this mode the REC output carries the audio signal coming from the line 1 or
CUE. This mode is selected by clicking Cue signal in the configuration auxiliary
output matrix.
When the REC output is configured in codec mode, it is also possible
to work in stereo. In that case, the REC output carries the left channel
audio of the received stereo signal. This operation mode requires to
be enabled from the web browser in order to disable the
compressor/limiter. For more information please read the chapter XI Operation examples.
V.3.3 RECORDING operation mode
In this mode, it is possible to add the audio contribution signals on the program
line to the return signal from the same line (CUE signal). One application might
be to record an interview or a retransmission.
This mode is selected by clicking Cue and Program signals in the auxiliary output
configuration matrix.

V.4 ‘AUX’ output.
This output supports many different configurations depending on the selected
audio sources in the auxiliary output configuration matrix of the web browser:
V.4.1 Technical specifications
6mm (1/4”) jack connector at the front panel.
Bandwidth 20Hz-20kHz (0.3dB).
Maximum output level: +20dBu.
THD+N < 0.005% @ 1kHz.
SNR < 100 dB.
Output impedance < 50 ohms.
V.4.2 Operation modes
Depending on which signals are selected from the auxiliary output configuration,
the AUX output supports different configurations.
