Sense inputs
The sense inputs of the three channels (left, right and subbass) are
arranged on a six pole barrier strip set into the rear panel within the area
labeled Sense IN. The Sense inputs are intended for connection to the
output signals of the amplifiers driving one cabinet of each the channels
being used : PS for the left and right channel, LSub for the subbass
channel.
Input sense connection is strongly recommended for proper operation of
the servo-control system. On PS15TDcontroller MKII (and PS10
TDcontrollers with serial numbers before #360) which do not have fall-
back mode, the cabinets will NOT BE PROTECTED if the sense lines are
unconnected.
Connection is made via the female part
- removable - of the connector
(supplied with the Controller) as
outlined below :

NB : The PS TDcontroller is insensitive to the polarity of the wiring of the inputs, contrary to some other
NEXO Controllers. It is highly recommended that the user read the all of the information provided below
regarding the wiring of Sense lines (0.0.0 : Recommendations for wiring the Sense lines).
Earth Lift
The push button labeled « Earth Lift » allows connection (depressed position), or disconnection (out
position) between the signal ground and the mains earth, which is itself linked to the chassis. Using this
button may help to eliminate hum due to ground loops created in the system.
Following functions concern PS15TD MK2 only
Voltage selector (PS15)
According to CEI65 and UL1419 norms, an external voltage selector is provided at the back of the unit. It
will allow the controller to work with either normalized voltage (230V or 115V).
WARNING : Changing the voltage selector requires changing the fuse.
