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.
