Rolls utilizes a way of switching phantom power ON and OFF thru a three pin jumper wire that is attached to the unit and a
external bridge clip to act as a switch for switching between two preset unit options. For example on other Rolls units it might
be for switching between phantom power on/off as illustrated above or it may be used for switching between ground/lift or
other options as denoted on the silk screening of the unit.
-To switch between options the Bridge clip can be moved from one option/side to the other just like a switch.
-To do this simply grab the bridge clip with a pair of needle nose pliers or tweezers and pull outward from the unit
disconnecting it from the pins of the unit completely.
-The middle pin is utilized in either position. In the above illustration (OFF) the middle pin is connected to the left side pin with
the bridge clip to have the phantom power OFF.
-To have the phantom power (ON) connect the middle pin and right pin together with the bridge clip as in the illustration below.
Please note that you must follow the silk screening of the unit to know what the jumper wire does and to which side is on or
off. All of our units are different, but great care is taken to insure that the silk screening is correct.
We use the bridge clip/jumper wire combination in place of switches due to there reliability. Switches break. Our system has
been in use for many years and we have never seen a single unit back with broken pins. We have seen many of our other
units back for repair for a simple broken switch.
We have found that customers like products better that do not break down in the field, and that they also do not like being
with out products that have to be sent back for repair. Knowing these facts we are committed to using this system in the future.
