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 meter on the receiver display when setting the transmitter gain. The OL indicator should only illuminate infrequently when you speak
loudly or play your instrument loudly.
BLX1
Rotate the audio gain adjustment
to increase(+) or decrease(-) the
gain until desired level is reached.
For instruments, turn gain to
minimum setting. For lavaliers,
increase the gain as desired.
BLX2
The BLX2 features two gain level
settings:
• Default
• -10 dB
Use the default setting for most
situations.
If
the receiver audio OL
indicator displays often, set the
microphone to -10 dB.
1. To change the gain to
-10
dB, hold
down the
channel
button until
a small dot appears in the lower
right hand corner of the transmitter
display.
2.
To
change the gain back to
default, hold the
channel
button
until the dot disappears.
