Using the XP40iw Wireless Microphone
Bear in mind also that the HT5H microphone is unidirectional which means it
picks up sound from the front of the mic and rejects sound from the rear. This
will help reduce the chance of feedback. 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”).
9. If you hear distortion at the desired volume level check the rear panel PEAK LED.
If it is lit red turn down the WIRELESS LEVEL until it lights red only occasionally. If
you still hear distortion, do the following:
• TheHT5transmitter'sGaincontrolhasbeenfactorypresettoprovideoptimum
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 slowly counterclockwise until the distortion
disappears.
Note that, following this setup procedure, you can always lower the Volume knob
of the XP40iw in order to further attenuate the output signal if necessary.
10. 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 XP40iw rear panel Audio Output Level switch is set correctly and that the
gain structure of your audio system is correctly set. If it is and the signal coming
from the XP40iw is still weak and/or noisy, do the following:
• TheHT5transmitter'sGaincontrolhasbeenfactorypresettoprovideoptimum
level for the particular microphone model being used and so no adjustment
should be necessary. Any weakness of signal should therefore simply be a
matter of the microphone being too far from the mouth; try moving it closer. If
this does not solve the problem, use the supplied plastic screwdriver to turn the
Gain control (trimpot) on the HT5 slowly clockwise until the signal reaches an
acceptable level.
