A – Yes. Legacy Electro-Voice bodypack transmitter input devices with 4-pin mini connectors are
compatible with RE3.
Q – I want to put together an eight-channel RE3 system with two remote antennas on the
stage feeding the receiver rack. What do I need?
A – First, choose the frequency band or bands your system will be operating in. Based on your
location, you’ll need to evaluate available spectrum and how it aligns with the RE3 band options.
Knowing that information, one option would be to select the same band for all eight sets. Another
option is to split the eight by selecting four sets from one band, and the other four from another
band, thereby allowing room to compensate for unforeseen changes. You’ll probably be rack
mounting your receivers, so you’ll need four RMK2 dual rack mount kits, which will mount the eight
receivers in four rack spaces. You’ll need two AASP active antenna splitters which will cascade
the RF from two antennas into the eight receivers. You’ll need either two PLPA passive log
periodic antennas, or two ALPA active log periodic antennas on stage. They will mount on
standard microphone stands. Choosing between the two will be influenced by coverage area and
the length of antenna cable between antenna and receiver rack. The PLPA, although passive, has
10dB of passive gain, and may be fine if the receiver rack is on stage, however the ALPA active
antenna has adjustable gain (selectable 3dB and 10dB amplified), and if the cable run to the
receiver rack is lengthy, it may be the best choice. You decide. You’ll need TWO low-loss coax
cables to run the antenna signals to the first AASP splitter. Choices are RE3-ACC-CXU25 twenty-
five foot, RE3-ACC-CXU50 fifty foot, RE3-ACC-CXU75 seventy-five foot, or RE3-ACC-CXU100
one hundred foot. The splitter has all cables required if you connect your remote antenna cables to
the rear of the first AASP, but if you want to attach the antenna cables at the front of the rack,
you’ll need to add an RE3-ACC-CXUF rear to front mount antenna cable kit. That should do it.
Q – Why am I not seeing much audio level on my receiver AF meter?
A – The transmitter input sensitivity likely needs to be adjusted. It has 30dB of adjustment (-15dB
at lowest gain to +15dB at highest gain). On the transmitter, press and hold SET until the
characters on the display begin to flash. Continue to progressively press SET until reaching the
sensitivity parameter. Press the up button to increase the displayed value. Pressing SET will store
the new setting. Continue working with this setting until the receiver’s AF meter yellow LED is
lighting upon high voice peaks. An occasional red LED will be OK.
Q – My receiver is in lock mode. How do I unlock it?
A – Press and hold the SET button for two seconds then use down button to select OFF. Then
press SET. Receiver is unlocked.
Q – Why does my receiver RF meter show RF signal present before I turn on the mated
transmitter?
A – There is a competing RF signal now present on that frequency. With the RE3 transmitter off,
follow the scan process and select a new clear frequency. Then turn on the transmitter and resync
it to the receiver’s new data.
Q – The frequency I’ve had my set tuned to has always worked flawlessly. Why is it that
when I traveled to an out-of-town gig, I’m getting interference there?
A – RF environments change city-to-city. When traveling, it’s important to remember that UHF
television broadcasts are not always on the same channel in every city. Something in the city or
