General Description
The Shure UAPF-X1 is an in-line passive RF lter to attenuate frequencies outside the
X1 band and intended to be used with any Shure X1 band wireless product that has
removable antennas, including SLX, ULX, and UHFR.

FeatUres

Filters out extraneous RF signals.•
Mountable on supplied desk-/wall-mount or on a microphone stand•
Extremely durable under the heaviest use•
Shure quality, ruggedness, and reliability•

application

Optimally, the unit should be located prior to any amplication of an RF signal.
Positioning should be tested and adjusted for each individual setup.
Antennas should be spaced far enough to obtain the widest possible RF eld and to
minimize RF signal drop out. In a diversity system, Shure recommends that antennas
be positioned at 45°.
