3. Product information
All information about the product, the scope of delivery and the available accessories.
Spectera System
Sensing Capabilities - Audio detection and transmission
Spectera devices (Base Station, DAD, SEK) build audio transmission system for professional
use. Once paired, SEK mobile devices can transmit audio signals captured by a connected
microphone over radio frequencies. Due to its bi-directionality, the SEK is able to receive
audio signals from DAD and the sound comes out of the headphones, if any connected. Here
how it works:
Transmission:
1. The microphone connected to the SEK picks up the sound and converts it into
electrical signals.
2. The SEK then prepares these signals for transmission by amplifying and modifying
them.
3. The signals are sent over radio waves to the DAD Antenna.
4. The DAD antenna changes the radio back into electrical signals and sent them to the
Base Station for further audio processing.
Receiving:
1. The Base Station forward audio signals to the DAD Antenna.
2. These signals are then prepared for transmission by boosting and modifying them.
3. The signals are sent over radio waves to the SEK mobile devices.
4. The SEK changes the radio back into electrical signals and at a further stage, sound
will be directed to connected headphones.

Connecting word clock
You can use the internal word clock on the Base Station or connect an external word clock.
You can also output the external word clock and cascade it up to 8 Base Stations.
The word clock output transmits only the external word clock that is connected via the word
clock input. The internal word clock is not output via the word clock output.
For more information about the word clock, see Word clock scenarios for digital
audio.
To connect an external word clock:
Use a coaxial BNC cable (75 Ω) to connect the external word clock to the word clock
in input.
46
| 4 - Instruction manual
To cascade the word clock:
Connect the cable from the word clock in input of the next Base Station to the word
clock out output of the previous Base Station.
The Base Station has been connected to word clock.
Word clock scenarios for digital audio
The Base Station supports two clock rates: 48 kHz and 96 kHz.
You can use either the internal word clock on the Base Station or connect an external word
clock.
An external word clock can also be forwarded to a downstream device via the word clock
output. This feature allows you to cascade up to 8 Base Station devices.
Note that only the word clock on the word clock input can be forwarded via the
word clock output. The internal word clock is not forwarded via the word clock
output.
47

Word clock with digital audio
If multiple devices with digital audio signals are connected in a production environment,
their clock signals must be synchronized via a word clock, otherwise audio errors occur. The
word clock of one device becomes the master. All of the other devices become slaves and
synchronize with the master.
Dante®
The Audinate Brooklyn III Dante® interface installed in the Base Station should be understood
as a standalone digital audio device with its own word clock and also has to be clocked either
internally or externally.
You require the Dante Controller software from Audinate for these settings. You
can access it using the link: Dante Controller.
Defining the master and slave
The Base Station word clock input, the Base Station internal word clock, the word clock
of the Audinate Brooklyn III Dante® interface, or the Dante® network can be defined as the
master.
For WebUI see: Audio interfaces.

The three most common causes of activation errors are as follows:
1. The Base Station was not connected properly and has no Internet connection (see
Solution 1: Establish a proper connection of the Base Station to the Internet).
2. The license server and/or NTP time server are/is unreachable due to missing port
permissions, preventing license key authorization and system clock synchronization
(see Solution 2: Open required ports for license activation and system clock
synchronization).
3. The license key was entered incorrectly or has already been activated and is in use
with another Base Station (see Solution 3: Check the activation code and contact
support if necessary).
253
| 5 - Knowledge base
Solution 1: Establish a proper connection of the Base Station to the Internet
Please connect the Base Station directly to a network with Internet access via a
switch or router.
Direct connections via laptop etc. are only supported in certain network configuration
(see Sharing Internet connection in small network setups). To eliminate this issue,
please avoid a direct connection with your device for license activation.
Solution 2: Open required ports for license activation and system clock
synchronization
Please contact your IT administrator to provide Internet access to the License Server
and any NTP server by opening the required network ports and to provide DNS
settings via DHCP to the device.
