Tips to
Improve
Wireless System Performance
If
you encounter interference or dropouts, try the
following
suggestions:
• Choose a different receiver channel
•
Reposition the receiver so there is nothing obstructing a
line
of sight to the transmitter (including the audience)
•
Avoid placing transmitter and receiver where
metal
or other dense materials may be present
•
Move the receiver to the top of the equipment rack
•
Remove nearby sources of wireless interference, such as cell
phones, two-way radios, computers, media players, Wi-
Fi
devices, and digital
signal
processors
• Charge or replace the transmitter battery
• Keep transmitters more than two meters
(6
feet) apart
• Keep the transmitter and receiver more than 5 meters (16 feet) apart
•
During sound check, mark trouble spots and ask presenters or performers to avoid those areas
Getting Good Sound
Correct Microphone Placement
• Hold the microphone within 12 inches from the sound
source. For a warmer sound with increased bass
presence, move the microphone closer.
•
Do not cover
grille with hand.
Wearing the Headworn Microphone
• Position the headworn microphone 13 mm (1/2 in.)
from the corner of your mouth.
•
Position
lavalier
and headworn microphones so that
clothing, jewelry, or other items do not bump or rub
against the microphone.
Adjusting Gain
Monitor the
audio
LED indicator
on
the receiver front panel when setting the transmitter gain.
•
Green: normal
levels
•
Red: excessive sound
levels
(overload).
The red LED
should only illuminate
infrequently when you speak loudly
or
play
your instrument
loudly.
BLX1
Rotate the audio gain adjustment to increase(+)
or
de-
crease(-)
the gain
until
desired
level
is reached.
For instruments, turn gain to minimum setting. For
lava-
liars,
increase the gain as desired.
SIIUR.E
BLX2
The BLX2 features two gain
level settings,
default
and
attenuated (-10 dB). The
default setting is used for most
situations.
If the receiver
audio
LED
flickers
red often, set
the microphone to attenuated. Use the
channel
button to
change the gain setting.
1.
Hold
down the
channel
button for 5 seconds.
A dot appears
on
the
lower
right-hand corner of the
LED display, which indicates
-1
0 dB gain setting has
been activated.
2. To change the gain back to default, hold
the
channel
button again for 5 seconds, or
until
the dot disappears.
