CXU25 will lose approximately 1.3 dB on the run, the 50-foot CXU50 will lose approximately
1.4 dB on the run, the 75-foot CXU75 will lose approximately 2.4 dB on the run, and the 100-
foot CXU100 will lose approximately 4.4 dB on the run. Factoring in the gains of the
antennas, the passive log periodic PLPA is +10 dB, the active log periodic ALPA is either +3
dB or +10 dB (selectable), and the active booster RFAMP is +10 dB. So for example, if your
antenna cable run is 100 feet, and you deploy ALPA (set to +10 dB) followed by CXU100 (-
4.4 dB), the net RF gain at the receiver is approximately +5.6 dB, which is fine. A handy way
to think of it is booster/antenna gain minus cable loss equals net received RF gain. We
should also emphasize that an RF boosting device should precede the loss, not make up
for it after the loss (place a booster at the antenna location, and not the receiver location).
Q – I’m using an RE3 bodypack wireless for my bass guitar with active pickups and I’m
blasting the receiver hard. What could be wrong?
A – Your bodypack transmitter input pad should be engaged. Locate the -20 dB attenuator
setting in the menu and set it to ON. If further transmitter audio signal gain reduction is
necessary, locate the sensitivity setting in the menu and bring the sensitivity down a few
dB as well.
