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-
liers, increase the gain as desired.
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 −10 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.
