Foreword
CAUTION !
This servicing instruction is for use by qualified service personnel only. To reduce the risk of electric shock
do not perform any servicing other than that contained in the operating instructions unless you are
qualified to do so.
Safety instruction
Mains Power
WARNING ! THIS APPLIANCE MUST BE EARTHED.
The green and yellow wire of the mains cord must always be connected to an installation safety earth or
ground. The earth is essential for personal safety as well as the correct installation of the system, and is
internally connected to all exposed metal surfaces. Any rack framework into which this unit may be
mounted is assumed to be connected to the same grounding circuit. (see also p.4)
NEXO TDcontrollers don’t provide a mean to switch off the unit from the front panel. As they are intended
to be rack mounted the back panel is not accessible during use. Therefore it is left to the user to provide a
disconnection mean readily operable.
Voltage setting
NEXO TDcontrollers use a switch mode power supply (SMPS). This SMPS accepts universal AC power
input voltages in the range 90V to 264V, and requires no manual adjustment for voltages in this range.
Mounting the TDcontroller in a rack (Grounding, shielding & safety issues)
The TDcontroller is intended for rack mounting. The only accessible part during use shall be the front
panel of the TDcontroller. Any space above or under the TDcontroller shall be obstructed with a blank
panel.
The rack is a free grounding and shielding structure and it provides extra shielding. Therefore, it is
desirable that the screws used to fix the TDcontroller in the frame or rack provide an electrical contact
between the chassis of the TDcontroller and the rack.
The primary reason for grounding is safety. Conformance to the applicable requirements of the authorities
having jurisdiction is, of course, mandatory. However, grounding also has an impact on electromagnetic
compatibility. From the EMC point of view, it is desirable to have a low impedance ground network, as a
current flowing in the ground network will then produce low voltage in the network. A low impedance
network can be obtained using a multipoint ground scheme, with as many closed ground loops as is
economically possible.
Fuse
The fuse provided in the unit will not blow during normal operation. If the fuse blows the TDcontroller
has malfunctioned. This fuse must only be changed by NEXO certified service personnel. In any case do
not replace the fuse with a non-certified NEXO fuse, as this will invalidate the NEXO warranty.

Mechanical issues
Removing the top panel
First be sure that the NX242 is disconnected from the mains. Wait 5 minutes to discharge the capacitors
To remove the top panel; unscrew the 11 screws circled in red in the above drawing (POZIDRIVE screwdriver).
When replacing the top panel pay attention to the 2 screws which are above the aluminum heatsink. They
should be screwed with a lesser torque than the other to avoid damaging the aluminum threading.
WARNING: Some of the NX components are sensitive to electrostatic discharges. Be sure to firmly hold the
chassis of the NX242 before touching any component inside. Always keep contact with the chassis to prevent
electrostatic discharge. If possible, use non-magnetic tools.
Removing the PCB
The remove the PCB; unscrew the 14 screws in blue square (POZIDRIVE screwdriver). Warning : the screw
pointed by the arrow is smaller than the other. It must be replace at the very same place to avoid so short circuit
problem (affecting slightly the overall dynamic range) on PCB v1.8

Hardware problem on NX242 s.n. 3880 to 4049
Abstract
This document deals with a hardware problem that can be found on any NX242 from serial number 3880 to
4049.
The symptoms of this failure is the following:
-Crackles on the outputs patched on the A Input of the NX242 that can be very audible.
-Blinking of the Sense green LED even without amplifier connected.
Please note that in case of emergency it is always possible to use the B input of the NX242 that does not
present noise.
Also note that in most of the cases, the noise disappears after a few minutes (after the NX warmed up).
The solution to solve this problem is to remove faulty capacitors on the NX242 PCB.
Hardware correction
Finding and removing the C1516 component
The C1516 component has been soldered on a few NX242 from serial number 3880 to 4049. In most of the
cases, this component is not present on the motherboard. If not, please go on to the next chapter.
Locate the C1516 component inside the NX242.
The C1516 is a SMD capacitor.
Here is a closer look on the C1516 component, near the connector for the RS-232 Interface.

Remove this component with a soldering iron. Be sure to let a clear path between the two pads of the PCB. The
footprint should look like the footprint of the component C1515 just bellow.
Finding and removing the “Flying” capacitor
First of all locate the Flying capacitor, on the picture bellow:
Now have a closer look on the component U5401. This component has a traditional capacitor, that can be blue
or orange soldered between the pin 2 and the pin 8, as you can see on the picture bellow.

Please note that the color of the capacitor has no importance.
Now, please check the manufacturer of the U5401 component. From NX242 serial number 3200 to 3879, the
component should be a Texas Instrument, and from serial number 3880 to 4049, the component should be a
Philips. Here are two pictures of the possible manufacturer:
The Texas Instrument component:
The Philips component:

NEXO NX242 DIGITAL TDcontroller Service manual rev100606
P.1
0
Only if you have a Philips component, you have to remove the added capacitor
You can unsolder the capacitor, or simply cut the legs as near as possible to the legs of the Philips component.
If you have a Texas component, you must have the capacitor between the pin 2 and the pin 8 of U5401.
Once this operation is finished, replace the cover of the NX242, with all of the screws, as they are important for
the shielding of the digital section of the controller. When you power up the unit again, it should boot normally,
and none of your settings should be lost. Check that the noise has disappeared on all the outputs (be sure to
check the input A of the controller).

Hardware fix for the Nxtension-CAI and the Nxtension-ES4
Abstract
This document deals with a hardware problem that can be found on Nxtension card with:
-Serial number up to 695 for Nxtension-ES4
-Serial number up to 299 for Nxtension-CAI
The symptoms of this failure are the following:
-Crackles or noise on all the outputs that can be permanent or punctual.
-When using an Nxtension-ES4, the noise disappears when switching from Analog to Digital input.
Also note that this problem mostly occurs with Nxtension-CAI cards.
The solution is to connect to a fixed potential a pin on the Nxtension board which was left floating.
Hardware correction
First and foremost, be sure to disconnect the NX242 from the mains before opening the top cover. Once the top
cover of the NX242 is open, you can directly do the hardware correction on the Nxtension-board itself.
Then locate the large header on the Nxtension card like on the picture above. On this header, you will have to
solder a jumper between two pins (one next to the other). These two pins are located 17 pins from the left or 12
pins from the right (see the picture bellow).

Bellow is a side view of the soldering: a hard wire is the best solution has it will be less sensible to vibration.
Once it is done, screw the cover back, and check that the NX is booting normally. Check that the audio is
passing through without any problem.
