9. Now it's time to set the audio levels. Turn on your connected amplifier and/or mixer but
keep its volume all the way down. Next, make sure that your transmitter is unmuted by
setting its Audio switch to "On." Then set the AF Level knob on the UR1 fully clockwise
(to its "10" setting); this is unity gain. If you are using the UH1 transmitter or if you are
using the UT1L transmitter with a connected lavalier microphone or headset, speak or sing
into the mic at a normal performance level while slowly raising the volume of your
amplifier/mixer until the desired level is reached. If you are using the UT1G transmitter
with a connected instrument, play the instrument at normal performance level while slowly
raising the volume of your amplifier/mixer until the
desired level is reached. If you are using a UT1L
beltpack transmitter equipped with a lavalier
microphone, note that correct lavalier placement is
critical to sound quality. We recommend that you
place it as shown in the illustration on the right—as
close to your mouth as possible but off to one side
(to minimize nasality) and unobstructed by clothing.
Bear in mind also that omni microphones (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 microphone
directly in front of a PA speaker (if this is
unavoidable, try using an equalizer to attenuate those
high- or mid-range frequencies which are causing the
feedback "squealing").
10. If you hear distortion at the desired volume level, first check to see whether the yellow
"Peak" LED on the UR1 is lit. If it is not, make sure that the gain structure of your audio
system is correctly set (consult the owners manual of your mixer and/or amplifier for
details). If the yellow "Peak" LED is lit, do the following:
• If you are using a UH1 transmitter, use the supplied plastic screwdriver to turn its
Microphone Input Level control (trimpot) slowly counterclockwise (towards the "Min"
position) until the distortion disappears.
• If you are using a UT1L transmitter with connected lavalier microphone or headset, its
Audio Input Level control has been factory preset to provide optimum level for the
particular lavalier or headset model being used and so no adjustment should be
necessary. Any distortion present should therefore simply be a matter of the
microphone being too close to the mouth; try moving it further away. If this does not
solve the problem, use the supplied plastic screwdriver to turn the Audio Input Level
control (trimpot) on the UT1L slowly counterclockwise until the distortion disappears.
• If you are using a UT1G transmitter with an instrument such as electric guitar or bass,
lower the output level of the instrument until the distortion disappears. Alternatively,
you can use the supplied plastic screwdriver to turn the Level control (trimpot) on the
UT1G slowly counterclockwise until the distortion disappears.
Note that, following this setup procedure, you can always lower the AF Level knob of the
UR1 in order to attenuate the output signal if necessary.
