Please read this guide carefully to ensure your personal safety as well as the safety of your equipment. Never
break off the ground pin on any equipment. It is provided for your safety. If the outlet used does not have a
ground pin, a suitable grounding adapter should be used and the third wire should be grounded properly. To
prevent the risk of shock or fire hazard, always be sure that the mixer and all other associated equipment are
properly grounded.
VOLTAGE SELECTOR SWITCH (4)
The RBN™112 has a voltage selector switch to allow switching between an input power voltage of 120VAC to a
range from 220VAC to 240VAC, all at either 50 or 60 cycles per second (Hz). It should be set to the proper volt-
age for your country out of the box. However, world conditions are such that some areas have power line voltag-
es differing from the voltage used by the majority of any given locale.
Be sure to check the position of the voltage selector switch to see that it matches the power line voltage used
locally. If it does not match, then to change the voltage to the correct one, follow the steps outlined below.
Changing the Voltage Range of the RBN™112
First, make sure the RBN™112 is disconnected from the power line, and that the power switch (1) is in the OFF
position.
Second, unscrew the screws holding the clear switch protector on the voltage selector switch (4) just a little, just
enough to allow rotation of the clear switch protector. The screws DO NOT need to be unscrewed very far.
Third, rotate the clear plastic protector about 90 degrees to uncover the voltage selector switch. One side of the
cover has a slot, the other just a hole, the side with the hole is the side that pivots.
Fourth, using a small flat blade screwdriver, push the red selector switch slide plate to the other side from where
it was. The voltage that is now visible on the red slide plate is the one you have selected.
Fifth, rotate the clear plastic protector back underneath the loosened screws, and tighten one down while hold-
ing the clear plastic protector in place. Tighten the other screw down, and make sure both screws are tight.
If the screws are over-tightened, this could damage the voltage selector switch clear plastic cover, so do not apply
excessive force to the screws!
Sixth, the fuse should be changed to the correct amperage rating. For an input power voltage of 120VAC, use a
10 amp rated, 250V 5 x 20 mm cartridge type time-delay fuse, which conforms to the international fuse classifi-
cation "T10AH".
For an input power voltage range of from 220VAC to 240VAC, use a 5 amp rated, 250V 5 x 20 mm cartridge type
time-delay fuse, which conforms to the international fuse classification "T5AH".
The IEC power cord that is correct for your locale can now be plugged into the IEC receptacle (3), and the Power
switch (1) activated to turn on the powered RBN™112 speaker system.
