RCF MONITOR 33T Mode D'emploi page 10

Connecting the MONITOR 33T and
MONITOR 33/WT speakers
These speakers can be used in either constant
systems (e.g. 25V, 50V, 70V, 100V) or constant impe-
dance systems.
To connect the speakers to constant voltage lines:
1. Use a screwdriver to turn the switch 1 and select
the power to be delivered as explained in the spe-
cific section. Should this switch be mistakenly pla-
ced in the Bypass position, the sound message will
not be distributed.
2. Use a screwdriver to turn the input voltage selector
2 so that the slot is set on the voltage of the sound
system (e.g. 70V).
3. Connect the input terminals: the RED terminal must
always be connected to the positive terminal (e.g.
70V) of the audio line.

To connect the speakers to constant impedance
lines:
1. Use a screwdriver to turn the switch 1 so that the
slot is set on the Bypass position.
2. Use a screwdriver to turn the switch 2 so that the
slot is set on the Bypass position.
3. Connect the input terminals: the RED terminal must
always be connected to the positive terminal (+) of
the audio line.
When the switch 2 is turned to the 0 position, the
speaker is disconnected from the line, and the sound
message is not distributed. The 25V input voltage can
also be used in constant impedance systems for con-
necting multiple speakers in parallel: the minimum
impedance of the 25V input, corresponding to the
20W position of the switch 1, is 31 ohms.
