DTD CONTROLLER INTRODUCTION
DTD Controller introduction
Welcome to the DTD controller manual. Please take some time to
read it and learn how to set up the device.
The DTD (Digital Temperature and Displacement) controller is a
loudspeaker controller dedicated to Nexo speakers.
It performs as a Nexo speaker system crossover, and provides
equalization, phase alignment and protection (by controlling the
speaker voice coil temperature and the cone displacement).
WARNING! Although the DTD Controller can be used
without computer, you will need to connect a computer running Nexo
Dory software at least one time before first use to select the proper
Nexo speaker setup (available on our website nexo-sa.com )
Audio Input and Output connections
How to integrate into the audio chain?
Place the DTD in the audio chain just before the power amplifiers,
typically at the output of a mixing desk or a routing matrix.
Typical installation for a touring system (using DTD-T)
Typical installation for a fixed installation (using DTD-I)
Note that the outputs of the power amplifier are connected to the
DTD-T, while its integrated front panel patch is connected to the
speakers. With the DTD-I, power output of the amplifier will have to
be split in two (one used for DTD-I feedback, the other going to the
speakers).
WARNING!
Unplug the device from mains before connecting
or disconnecting any cable to it.
The DTD can be fed through four type of audio signal:
•
Balanced Analog Inputs (using 24 bits / 48 to 96 KHz converters)
•
AES/EBU Input (24 bits / 44.1 to 96 KHz sample rate)
•
USB Audio Input (16 bits / 48 KHz sample rate)
•
Dante
tm
Input (Optional) (24 bits / 44.1 to 96 KHz sample rate).
Connecting the DTD-T audio inputs
On DTD-T, use front panel female XLR3 connectors to connect the
balanced analog input signal. For both channels a male XLR3 is available
in parallel to link to other DTD.
Please check your audio source manual to know how many DTD
devices can be connected in parallel on its output.

streams can be
received from the back panel RJ-45 connector.

Connecting the DTD-I audio inputs
On DTD-I, use back panel terminal block connector to connect a
balanced analog input signal.

AES/EBU signal can also be connected to the back panel terminal block
connector.

Connecting DTD the audio outputs
The DTD outputs must be connected to professional grade audio
power amplifiers.
Up to ten amplifiers channels can be connected in parallel on one DTD
output.
On the DTD-T, use the back panel male XLR3 connectors to connect
the balanced analog outputs to the amplifier inputs.

On the DTD-I, use the back panel terminal block connectors to
connect the balanced analog output signal to the amplifier inputs.
