1. INTRODUCTION.
1.1. Fields of application of the product.
Using off-the-shelf routing equipment to send audio over IP in small to medium-sized systems
offers cost advantages over synchronous solutions using AES-10 (MADI) or TDM buses. These
have higher capacity, but require powerful hardware. Besides, large TDM systems can reduce
their cost and at the same time increase their flexibility when they are combined with IP audio
links to connect a few circuits with a central router.
That’s why, when developing the IP audio routing system at AEQ, we have created not only IP
connection devices for the consoles, but also connection panels that allow for audio input and
output installation wherever it’s necessary, as well as access boards for the AEQ BC2000D
router.
On the other hand, AEQ insists on offering interoperability with third party devices for the
convenience of our customers. Because of that, the solution we now present is based on
AUDINATE’s technology that is operating with extraordinary performance, making our systems
100% compatible with a wide selection of equipment for Broadcast, Recording Studios and
Professional Audio (see full listing at www.audinate.com).
Please consult the AEQ AoIP user's manual for more information.

1.2. Description of NETBOX 32 AD audio interface.
NETBOX 32 AD is an interface for multi-channel AoIP. It allows you to insert and extract audio
channels in a system based on DANTE technology, at locations where the installation of AEQ
digital consoles is not planned. Due to its high input and output capacity, it is especially suitable
for central controls and link dispatches and also to increase or distribute the capacity of TDM
BUS matrices such as the AEQ BC2000D.
NETBOX 32 AD features 32 input and 32 output channels organized in 16 mono analog and 8
stereo digital channels. The stereo digital audio channels can be configured as AES/EBU or
SPDIF standard. It also incorporates 16 GPIs and 16 GPOs (each GPIO connector includes a
power supply pin to feed the external circuitry), as well as 256 virtual GPIs and 256 virtual
GPOs.
The unit can be turned into a 64x64 mixing and distributing audio matrix ("NETBOX 32 AD MX
Audio Router 64x64") by mixing specific firmware versions, a user license and "AEQ Netbox
RTC" application. Please consult section 3.2.2.1 of this manual and the user's manual of "AEQ
Netbox RTC" application for more information.
1.3. Description of NETBOX 8 AD audio interface.
NETBOX 8 AD is an interface for multi-channel AoIP. It allows you to insert and extract audio
channels in a system based on DANTE technology, at locations where the installation of AEQ
digital consoles is not planned. Due to its small footprint, it can be useful to give IP access to
analog or digital consoles that are not ready for this type of connectivity from factory, for
recording rooms, talk-rooms or any other auxiliary location.

NETBOX 8 AD features 8 inputs and 8 outputs, organized in 4 mono analog and 2 digital stereo
channels. Stereo digital ones can be configured as AES/EBU or SPDIF standards. The second
digital stereo channel can also be switched to a USB connector to ease the connection to an
audio workstation. It also provides 4 GPIs and 4 GPOs (the GPIO connector includes a power
supply pin to feed the external circuitry), as well as 256 virtual GPIs and 256 virtual GPOs.
The unit can be turned into a 16x16 mixing and distributing audio matrix ("NETBOX 8 AD MX
Audio Router 16x16") by mixing specific firmware versions, a user license and "AEQ Netbox
RTC" application. Please consult section 3.2.2.1 of this manual and the user's manual of "AEQ
Netbox RTC" application for more information.
1.4. Description of NETBOX DSP audio router.
NETBOX DSP device is able to receive audio from the DANTE network and then return it,
mixed and processed, to be used in another device or subsystem. It can also generate a test
tone (1KHz) and vumeters of all the inputs and outputs.
There are 4 different versions of NETBOX DSP: NETBOX DSP 64, NETBOX DSP 96,
NETBOX DSP 128 y NETBOX DSP 160, with routing and mixing capabilities on 64, 96, 128
or 160 inputs to any of the 64, 96, 128 or 160 outputs in the AoIP network, respectively. It's
possible to add any quantity of inputs (up to 160 depending on the version) in any of the
outputs. In addition, there is gain control for all the inputs, outputs and cross points. Any output
can also be muted.
All 4 versions have the same processing capability on a maximum of 64 selectable inputs, that
can be sent processed to any of the outputs. The available processes are:
•Frequency: high-pass, low-pass and band-pass filters and 4-band parametric equalizer.
•Dynamics: compressor, expander, noise gate, limiter and DLP combinations.
•Delay.
It also incorporates 16 GPIs and 16 GPOs (each GPIO connector includes a power supply pin
to feed the external circuitry), as well as 256 virtual GPIs and 256 virtual GPOs that can be
transported through the IP network between compatible devices (this way, a GPI can drive the
GPOs of other devices).

2. PHYSICAL DESCRIPTION OF THE UNITS.
In order to understand the installation and cabling process associated to each unit, first you
need to be familiar with the connectors and other specific elements of the AoIP solution
described in this manual and the equipment front and back panels.
2.1. NETBOX 32 AD interface physical description.
2.1.1. Description of the front panel.
There are indicators related to the unit status, communications and audio levels.
POWER ON LED: indicates the status of the unit power supply.
•Off: no mains input.
•Green: power supply ON.
LAN LEDs: indicate the status of the audio local area network: LAN 1 (main interface)
and LAN 2 (secondary interface).
Status:
•Off: no local network connection.
•Blinking green: link is established at data level.
If the boards are wired to a dedicated audio network using a switch, only LAN 1 should
be blinking. If the wiring is connected in "Daisy Chain" mode, without switches, or there
is a redundant network, both LEDs should be blinking. IMPORTANT NOTE: When there
is a redundant network, primary and secondary interfaces must be connected to
separated networks.
AUDIO LEVEL LEDs: Each LED indicates the level of the corresponding device audio
input / output:
•LED off: the channel is muted, or transmits or receives (depending on whether
it is an output or an input) at a level below -60dBFS.
•Green LED: channel is transmitting or receiving audio (depending on whether it
is an output or an input) at a level between -60dBFS and -20dBFS.
•Amber LED: channel is transmitting or receiving audio (depending on whether it
is an output or an input) at a level between -20dBFS and -6dBFS.
•Red LED: the channel is saturated or "clipping" (above -6dBFS).

Remarks:
-Each of the eight digital audio inputs and outputs include two different audio channels,
according to AES 3 or SPDIF standard.
-The first digital input (17-18) synchronizes NETBOX 32 with the source connected to it,
emitting an AES 3/SPDIF or AES 11 formatted stream.
-The outputs can be used to provide synchronization to other devices that can extract it
from an AES 3 formatted audio stream.
2.1.2.3.1. Digital inputs/outputs jumpers configuration.
IMPORTANT NOTE: Access and configuration of the configuration jumpers require a previous
experience in installing and configuring computer or electronic cads. Don’t open the unit if you
lack this experience in order to avoid risk of electrical shock or damages to the system.
Digital inputs and outputs are programmed by default as AES/EBU. If compatibility with
SPDIF equipment is required, you must open the unit and change the corresponding
configuration jumpers.
-Opening the unit.
It’s VERY IMPORTANT to turn first the equipment off and disconnect the power supply
cable. Remove the 12 screws located at the top cover. Pull up from the top cover and
remove it.

is a redundant network, both LEDs should be blinking. IMPORTANT NOTE: When there
is a redundant network, primary and secondary interfaces must be connected to
separated networks.
AUDIO LEVEL LEDs: Each LED indicates the level of the corresponding device audio
input / output:
•LED off: the channel is muted, or transmits or receives (depending on whether
it is an output or an input) at a level below -60dBFS.
•Green LED: channel is transmitting or receiving audio (depending on whether it
is an output or an input) at a level between -60dBFS and -20dBFS.
•Amber LED: channel is transmitting or receiving audio (depending on whether it
is an output or an input) at a level between -20dBFS and -6dBFS.
•Red LED: the channel is saturated or "clipping" (above -6dBFS).

Remarks:
-Each of the two digital audio inputs and outputs include two different audio channels,
according to AES 3 or SPDIF standard. The second one has also two channels in USB
connector when the switch is in the lower position.
-The first digital input (5-6) synchronizes NETBOX 8 with the source connected to it,
emitting an AES 3/SPDIF or AES 11 formatted stream.
-The outputs can be used to provide synchronization to other devices that can extract it
from an AES 3 formatted audio stream.
USB Digital input and output 2 (7-8).
When the rear switch is in the lower position, AEQ NETBOX 8 provides the second stereo
digital input through the USB type-B connector labeled "USB". NOTE: The second output is
always available through the DB15 connector as well as through the USB connector, regardless
of the switch position.

When connecting the USB module to a PC through the USB port, the PC automatically
recognizes it as a new audio device (identified as "USB Audio CODEC"). Audio can be sent to it
from any playback program, like with any other professional external soundcard. Also, audio
can be recorded from NETBOX by using any recording application. The card is "plug&play" on
Microsoft Windows™ operating systems and Apple Computer Mac OS™, not requiring any
special driver.
The supported sampling rates are 32 KHz, 44.1 KHz y 48 KHz, with internal Sample Rate
Converter (SRC) to the 48 KHz frequency used internally by the DANTE-based AoIP AEQ
system.
2.2.2.3.1. Digital inputs/outputs jumpers configuration.
IMPORTANT NOTE: Access and configuration of the configuration jumpers require a previous
experience in installing and configuring computer or electronic cads. Don’t open the unit if you
lack this experience in order to avoid risk of electrical shock or damages to the system.
Digital inputs and outputs are programmed by default as AES/EBU. If compatibility with
SPDIF equipment is required, you must open the unit and change the corresponding
configuration jumpers.
-Opening the unit.
It’s VERY IMPORTANT to turn first the equipment off and disconnect the power supply
cable. Remove the 3 screws located at the top of the rear panel and the 3 one located
at the front of the unit’s base. Pull up from the top cover and remove it.
-Finding the jumpers location.
Place the unit with the front facing towards you and recognize the following zone inside
it:

-Programming digital inputs 1 and 2 as S/PDIF.
In order to use S/PDIF inputs, the programming described below adapts levels and
unbalance signals by joining IN1- and IN2- to their associated grounds, so each signal
is taken from the corresponding IN+ and its GND (or IN-). Take note that when the rear
switch is in USB position, the digital input 2 will be placed at the USB connector
regardless of the configuration programmed by jumpers.
At the "DIGITAL INPUTS AND OUTPUTS PROGRAMMING ZONE", you can change
the inputs one by one from AES/EBU to S/PDIF by moving the 5 jumpers associated to
each input from position 1-2 (up) to position 2-3 (down), as shown in the following
image:
-Programming digital outputs 1 and 2 as S/PDIF.
In order to provide outputs to S/PDIF equipments, the programming procedure
described above adapts the levels and unbalances the signals by joining OUT1- and
OUT2- to their corresponding GND, so the signal is taken from each OUT+ to OUT– (or
GND). Take note that the digital output 2 will be duplicated at the USB connector
regardless of the configuration programmed by jumpers.
At the "DIGITAL INPUTS AND OUTPUTS PROGRAMMING ZONE", you can change
the outputs one by one from AES/EBU to S/PDIF by moving the 4 jumpers associated
to each output from position 1-2 (up) to position 2-3 (down), as shown in the previous
image.
