RE3 UHF Wireless
to increase system range. The fourth thing to check is transmitter output power. If a
compromised range is accompanied with low RF signal on the receiver's RF meter, set the
transmitter output power to high, then look for improved range.
Q - Why is it hard to find an open frequency in my location?
A - RE3 shares the UHF radio spectrum primarily with UHF television broadcasters.
Geographically, some broadcast areas are more densely packed with television broadcast
signals than others. A full system scan looks through the entire tuning bandwidth of the
receiver and will locate frequencies which are not affected by UHF television or other RF
signals. Knowing your local RF environment is important. Those local television stations which
broadcast their strong and wide signals into the air are regulated by the government, and
consulting government databases will help identify the frequency areas occupied by local
broadcasters. RE3 tuning bandwidths are relatively wide, allowing generous tuning options,
however if the airwaves aligning with your particular RE3 tuning bandwidth are filled up with
UHF television, finding open frequencies will be difficult. Selecting the best band for your area
is important. Something to consider is if you are using your RE3 set in the USA or Canada, the
6M band will have no competing UHF television signals because 653-663MHz is designated for
wireless microphones only as a result of the reallocation of 600MHz initiatives.
Q - I manually created frequencies for my multi-channel system. Why am I getting
interference between the channels?
A - Manually creating custom tuning schemes without the assistance of frequency coordination
software may contribute to the problem described. RE3 frequency groups are strategically
created to be intermodulation free using advanced frequency coordination software. It's likely
that your self-made grouping has created destructive intermodulation artifacts which would be
avoided by staying with our factory groups. Use RE3 factory groupings. They work well.
Q - Why doesn't the extra RE3 transmitter I bought online work with my RE3 set?
A - The set you originally purchased was pre-configured with a matching transmitter and
receiver, which both operate in the same frequency band (5L, 5H, 6M, etc.). If you add
another transmitter, it has to be of the same frequency band to work. As this particular
question is about additional transmitters, it should be pointed out that adding a second
transmitter to an existing set with plans to use both transmitters at the same time with the
one existing receiver will not work. At any given time, one of the two transmitters tuned to the
receiver's frequency must be off. If they are both on and the same time, substantial
interference will occur.
Q - Will the lavalier microphone I have with my older RE-2 system work with RE3?
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
