E2S BExL25E Instruction Manual page 4

On 100V line units the end of line resistor used must have a
minimum resistance value of 4k7 ohms and a minimum
wattage of 2.5 watts. The terminal numbers, across which the
resistor should be fitted, will depend on the output level
selected and are given in the following table:-
Terminals BExL25E (25W)
A - B 25W
A - C 12.5W
A - D 6W
A - E 2W
BExL25E and BExL15E 100V Line Loudspeakers
Flameproof Enclosure
On low impedance units the end of line resistor used must
have a minimum resistance value of 2k ohms and a minimum
wattage of 0.5 watts or a minimum resistance value of 500
ohms and a minimum wattage of 2 watts. On the low
impedance units care must be taken with the polarity of the
monitoring voltage. If an end of line resistor is fitted to a unit
the links on the printed circuit boards of all loudspeakers in the
line must be cut for the dc blocking capacitors to be in circuit in
order to dc monitor the line (see figure 5).
