Royer Labs R-122V - Manual (Page 9)

CAUTION!
Never attempt to bypass a fuse or use one of a higher
rating! Not only is this an unsafe practice, but it will void
the factory warranty.
Voltage Changeover
The power supply can be set to operate from voltages
ranging from 100 to 240 volts AC. For 230V operation, use
the 240V setting. A small window at the rear of the Input
Power Module will display the current voltage setting. To
change operation to a different AC voltage requires
repositioning a selector drum within the module. Remove
the power cord and open the module door in the same
manner as to access the fuses. The drum can be removed
with a small pair of needle nosed pliers or the thumb and
forefinger (Image 5). Rotate the drum for the desired
voltage so that the selected voltage will appear in the
window of the module (Image 6). Gently push the drum
back into position and close the door. The door will snap
shut when fully closed.
It is important to note that changing voltage settings also
requires changing the fuses to different values. The correct
values can be found in the specifications section of this
manual.
Operation
There are a few important facts about ribbon microphones
that are key in understanding how to use them intelligently.
1. The R-122V is a side address, bi-directional microphone
and it’s rejection in the “dead” areas is very strong. Due
to this directionality, the R-122 should be placed at 1.3
times the distance normally used with omni-directional
microphones, or at about the same distance used for
cardioid microphones. This method is used to achieve
the same ratio of direct to reflected sound.
2. In the horizontal plane, the R-122V does not
discriminate against the highs off axis; nor does it boost
highs on axis. Therefore, several instruments or
vocalists can be placed in front of the microphone
without favoring the performer positioned in the center
