12.3
) contains the following:
X10  Flying leads - Two flying leads (30 cm) with 
high-temperature insulation to install the EOL 
supervision board in a loudspeaker (see section 
12.3.3).
S700  Address selector - An address selector to set 
the address of the EOL supervision board (see 
section 12.4).
S701 Address selector - An address selector to set 
the address of the EOL supervision board (see 
section 12.4).
C540 Capacitor - A capacitor for factory adjustments. 
Do not touch this capacitor.
R441 Resistor - A resistor for factory adjustments. Do 
not touch this resistor.
12.3 Installation
12.3.1 Supervision control board
Proceed as follows to install the supervision control 
board in the PRS-xPxxx Power Amplifiers:
1 Remove the lid from the power amplifier and locate 
the output board (see figure 12.4).
2 Snap the supervision control board on the ‘table’ 
bracket (see figure 12.4).
3 Fit the supplied flat cable to the connector on the 
output board and the supervision control board. Do 
not twist the flat cable and fit the polarization pin of 
the flat cable in the hole in the PCB next to the 
connector.

Warning
To prevent the hazard of electric shocks, 
disconnect the mains cord and the back-up 
power supplies from the power amplifier before 
starting installing the supervision control board.
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. See section 1.2 Intended 
audience.
Warning
The electronics inside the power amplifier and 
on the supervision control board are susceptible 
to electrostatic discharges. Wear an anti-ESD 
bracelet during the installation of the 
supervision control board.
Note
In the spare amplifiers also multiple line 
supervision boards must be installed for those 
channels that have multiple line supervision 
boards in the corresponding main amplifier 
channels. Otherwise, a Line supervision master 
mismatch fault event is generated. Single and 
multiple line supervision boards are not 
compatible.
