DTD-T
DTD-I
Flexible Inputs system
The new generation of NEXO Digital
TD Controllers offers the same sound
quality and processing algorithm than
our high end NXAMP range at a very
competitive price.
DTD mains features
 Speaker controller for PS and LS
range, provides digital processing issue
from the NXAMP technology (Crossover,
EQ, time alignment and speaker
protections).
 High-end Balanced Stereo Analog
inputs, AES input, USB input and
optionnaly Dantetm.
 High-end Balanced Analog outputs for
PS (Stereo) and LS (mono sum).
 Automatic Amplifier Sensing with no
setting required from user.
 Simple control from the front pannel
(Sub Gain, Main Gain, Crossover mode) or
advanced control using USB port.

The DTD offers efficient speaker processing with
unmatched input flexibility : On top of the High-end
Stereo balanced inputs, an AES input and a USB
input (driverless USB audio playback from many
OS) will allow the DTD to be connected quickly in
any situation. Dantetm input is also available as an
option (see ordering information).
State of the Art signal processing
Despite its easyness of use, the DTD is hidding
state of the art audio processing, offering high
precision EQ and Lienear Acoustic Phase
algorithm, phase compatible with other Nexo
speakers, inherited from our NXAMP range of
powered TDcontroller.
The DTD uses high-end AD and DA converters, 64
bits / 96 KHz DSPs, and finally an analog IN to
analog OUT dynamic range of more than 112 dB,
while distortion is keep under 0.001%.
The DTD-I is the Installation version, with all
connectors (except mini-USB) at the back on
barrier strip. No hardware control , everything is set
up from a PC/Mac computer connected on the
USB port, allowing the settings to be locked and
thus prevent any accidental changes.
User Mode
While front panel switch and knobs allows basic
setup of the DTD-T without the need of a
computer, the User Mode that can be set up
through the USB port offers more possibility like:
 Speaker and Sub model selection.
 Crossover Frequency selection.
 Delay on mains and sub outputs.
 Gain control for each output.
 Input/Output meters, including protections.
 User EQ (2x 8 bands parametric EQ)
 User limiters.
 Settings lock with password.
Updatable firmware
The USB port allows also to update the unit
firmware, to add new functions or to download
new NEXO speakers presets.
Installation or Touring versions

Digital TD Controller for NEXO
PS Speakers and LS Subs.
The DTD is a unique tool, combining advanced
signal processing, inherited from the NXAMP, whith
an unmatched easyness of use.
The Digital TDcontroller range is composed of two
models, both housed in a rugged low depth steel
19” case and featuring a universal power supply.
The DTD-T is the Touring version, with its analog
input and output connectors (XLR and Speakons)
on the front pannel, thus saving the cost and room
for an extra patch panel unit. Front panel display
shows the current PS/LS setup, two hardware
knobs for Sub/Main output gain, and a switch for
selecting Wideband, Crossover or User (i.e.
custom) mode.
