8. Microphone and Instrument Operation
The transmitter is now ready to use. The
RECEIVED RF LEVEL ICON (11a)
, and
either the
A
or
B DIVERSITY ICON (11b)
on the UHF-16 receiver should now be lit,
indicating a received signal from the transmitter. The receiver
MUTE LED
INDICATOR (X)
should be off.
a. Instrument Use
. Plug the 1/4" phone plug from
the INSTRUMENT CORD (23)
into the instrument. Verify that the
INPUT SELECTOR SWITCH (21)
is in the
GT
position. When ready to play, slide the audio
OFF/STANDBY/ON SWITCH (26)
to the
ON position. Adjust the volume of the receiver as per the
Audio Output Instrument
Connections
section of the above UHF-16 receiver instructions.
(Note: The
INPUT LEVEL CONTROL (30)
is deactivated and not used when the UB-16
is in GT, instrument mode. Levels should be adjusted with the volume control of your
instrument.)
(Note: Scratchy noises can sometimes occur when some electric guitars with dirty pots or
connections are used with any wireless system. Therefore, the supplied
INSTRUMENT
CORD (23)
has a factory installed capacitor inside the 1/4" plug. This capacitor
provides first order filtering of the RF signal from the cord into the guitar and eliminates
virtually all scratchy noises. Should your equipment still give you scratchy noises, we
suggest these steps to eliminate them:
1) Make sure all guitar volume and tone pots are clean and all contacts are solid–
this is very important.
2) A 47pf capacitor soldered across the hot to ground terminals of the guitar's
volume and tone pots will provide extra filtering.)
b. Microphone Use
(with either a lavalier or headworn microphone)
Secure the connection from the
LAVALIER (25)
or
HEADWORN MIC CORD (24)
by turning the slip ring on the plug into the transmitter clockwise to thread it on to the
jack. To unplug, reverse the process. To use the lavalier mic, attach it at chest level. Do
not place it too close to the mouth–a distance of about six inches usually works best. To
use the headworn mic, place it on the head and adjust the boom so that the mic is about
one inch to the side of the front of the mouth.
When ready to speak, verify that the
INPUT SELECTOR SWITCH (21)
is in either the
HM
position (for a connected headworn mic, or the
LT
position for a lavalier mic and
slide the
OFF/STANDBY/ON SWITCH (26)
to the ON position. Adjust the volume of
the receiver as per the
Audio Output Microphone
For optimum performance, an
INPUT LEVEL CONTROL (30)
is provided. Adjust the gain by turning the control
with the supplied small slotted screwdriver. For lavalier mic use, it is recommended that
the level be set at about 2/3 maximum. For headworn mic use, it may be advisable to turn
the gain down somewhat, depending on the volume levels expected. In either application,
experiment and set for maximum possible gain without audible distortion on the high
