Setting Up and Using the
UHF Series System
unobstructed by clothing. Bear in mind also that omni-directional micro-
phones (mics which pick up signal from all directions) are more prone to
feedback problems than unidirectional (cardioid or supercardioid) ones;
in general, you can avoid feedback by taking care not to use any micro-
phone directly in front of a PA speaker (if this is unavoidable, you can
try using an equalizer to attenuate those high frequencies which are
causing the feedback “squealing”).
4. Place a fresh 9-volt alkaline battery (not supplied) into your UT-4 or
UH-4 transmitter, taking care to observe the polarity markings (if you are
using a UH-4, follow the battery installation instructions given on page
14). We recommend the Duracell MN 1604 type or equivalent. We do
not recommend the use of rechargeable Ni-Cad batteries because they
do not supply adequate current for any significant time period. For the
moment, leave the transmitter turned off.
5. With the power to your amplifier and/or mixer off, make the physical
cable connections between the output of your UR-4 receiver (using
either the balanced or unbalanced jacks)* and the input of your amplifier
or mixer. If you are using professional (+4) equipment, the balanced
jack is preferable since it will deliver an electromagnetically cleaner
signal. When using a mixer that provides low impedance mic inputs,
always connect the UR-4 output to those mic inputs as opposed to line-
level (high impedance) inputs. Also, do not connect the output of the
UR-4 directly to the line-level input of signal processors; to apply effects
to the UR-4 output signal, connect signal processors to mixer insert
points.
6. Connect the supplied 3-pin “EEC” plug into the UR-4 rear panel AC
connector and plug the other end into any grounded AC socket.
7. Turn the Volume knob on the UR-4 receiver completely counter-
clockwise (to the “0” position) and depress the power switch to turn the
unit on. The “Power” LED in the display section will light up.
* If required, both the balanced and unbalanced outputs can be used
simultaneously.
