Setting Up and Using the
UHF Synth System
segments should light up. If you are using the UT-5 transmitter with a
connected instrument, play the instrument at normal performance level
while slowly raising the equivalent AF Level knob on the receiver to a
level of approximately “8”; again, one or more segments in the AF Level
display should light up as you do so.
9. Temporarily mute the audio signal by placing the UT-5 or UH-5
Audio switch to the “off” position. Then turn on your connected amplifier
and/or mixer but keep its volume all the way down. Next, unmute the
audio signal (by placing the UT-5 or UH-5 Audio switch to the “on” posi-
tion) and speak into the microphone (or play the instrument) at a normal
performance level. Slowly raise the volume of your amplifier/mixer until
the desired level is reached. If you hear distortion, use the supplied
plastic screwdriver to turn the Mic or Instrument control (trimpot) on the
transmitter slowly counterclockwise until the distortion disappears. If
you hear a weak, noisy signal, do the reverse: use the supplied plastic
screwdriver to turn the Mic or Instrument control (trimpot) on the trans-
mitter slowly clockwise until the signal reaches a good level.
10. If you are using the UR-5D receiver and you wish to keep the two
output signals separate, make sure the Output Mixing switch on the rear
panel is in the “Off” position. If you wish to mix the two signals together,
set the switch to the “On” position; the two output signals will then be
mixed together and routed to all four output jacks.
The basic rule of thumb for wireless audio systems is to always try to
minimize the distance between transmitter and receiver as much as
possible and also to try to maintain “line of sight” between the two (that
is, the person using the transmitter should be able to see the receiver
antennas). In fixed installations such as A/V or corporate conference
rooms or for extended range applications (where the transmitter and
receiver are more than 150 feet apart), it may be desirable to remote the
receiver antennas so that the strongest possible signal is received from
the planned transmission points. This can be accomplished by using
standard BNC connections and 50 ohm coaxial cabling that is suitable
for up to 1 gigaHertz bandwidth usage. For more information, see the
“Trouble-shooting” section on page 21.
