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

of the group.
