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 Volume knob on the SR55 or SR5 fully counterclockwise. If you
are using the HT5 transmitter or if you are using the ST5 transmitter with a connected lavaliere
microphone or headset, speak or sing into the mic at a normal performance level while observing
the SR55 or SR5 front panel Audio Meter. If you are using the ST5 transmitter with a connected
instrument, play the instrument at normal performance level while observing the SR55 or SR5
front panel Audio Meter. If the "0" (unity gain) segment is lighting steadily, with just occasional
higher excursions, the audio level is correctly set. If not, use the supplied plastic screwdriver to
slowly adjust the HT5, or ST5 Gain control (trimpot) until the SR55 or SR5 Audio Meter "0" (unity
gain) segment lights steadily (with occasional higher excursions). Then slowly raise the SR55 or
SR5 Volume knob to the 2 o'clock position (unity gain) and, finally, set the volume of your ampli-
fier/mixer until the desired level is reached. If you are using a ST5 beltpack transmitter equipped
with a lavaliere microphone, note that correct lavaliere 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 (or
if the "+6" segment LED in the Audio Meter is lighting fre-
quently), first check that the SR55 or SR5 rear panel Audio
Output Level switch is set correctly. Next, make sure that
the gain structure of your audio system is correctly set
(consult the owners manual of your mixer and/or amplifi-
er for details). If you still hear distortion, do the following:
• If you are using a HT5 handheld transmitter or an
ST5 transmitter with connected lavaliere micro-
phone or headset, its Gain control has been factory preset to provide optimum level for the
particular microphone 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 Gain control (trimpot) on the HT5 or ST5 slowly counterclock-
wise until the distortion disappears.
• If you are using a ST5 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 Gain control (trimpot) on the ST5 slowly coun-
terclockwise until the distortion disappears.
Note that, following this setup procedure, you can always lower the Volume knob of the SR55 or
SR5 in order to further attenuate the output signal if necessary.
11. Conversely, if you hear a weak, noisy signal at the desired volume level (and with the Volume
control of the receiver turned fully clockwise), again make sure that the SR55 or SR5 rear panel
Audio Output Level switch is set correctly and that the gain structure of your audio system is
