Tips to Improve Wireless System Performance
If you encounter interference or dropouts, try the following suggestions:
Getting Good Sound
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
• 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
Use the default setting for most
situations. If the receiver audio OL
indicator displays often, set the mi-
crophone 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 de-
fault, hold the channel button
until the dot disappears.
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.
