Single System Set Up
Before you begin, turn off all transmitters and turn on any equipment (other microphones or personal monitoring
systems) that could cause interference during the performance.
1. Press and release the group button on the receiver.
The receiver scans for the clearest group and channel.
8/24
Shure Incorporated
Note: If you want to stop the scan, push the group button again.
2. Turn on transmitter and change the group and channel to match the receiver (See Setting Transmitter Group
and Channel).
Once the system is set up, perform an audio check and adjust the gain if necessary.
Setting Transmitter Group and Channel
Transmitter group and channel must be manually set to match the receiver.
Group (letter)
1. Press and release the group button on the transmitter to activate the display. Press the group button again and
the display flashes.
2. While the display is flashing, press the group button again to advance to the desired group setting.
Channel (number)
If channel needs to be changed, follow the same procedure using the channel button instead of the group button.
Note:
• When the group and channel correctly match the receiver, the RF bars and battery LED on the receiver illumi­
nate.
• After manual setup, the transmitter alternately displays the group and channel setting for about two seconds.
Multiple System Set Up
Up to 12 systems can operate simultaneously (band and RF environment dependent).
Important: Set up each system one-at-a-time. Once a receiver and transmitter are tuned to the same group and
channel, leave the transmitter powered on. Otherwise, scans from the other receivers will not detect that channel
as occupied.
Turn on any other equipment that could cause interference during the performance so it will be detected during the
group and channel scans in the following steps.
9/24
Shure Incorporated
Before you begin system set up, turn all receivers ON and all transmitters OFF.
For the first receiver:
1. Perform a group scan to find the group with the most clear channels.
2. Turn on the first transmitter and change the group and channel to match the receiver.
3. Leave the transmitter on and continue with the additional systems.
Note: If the selected group does not contain enough open channels, manually select group "d" when setting up
larger systems.
For each additional receiver:
1. Manually change the receiver to match the group setting of the first receiver. Recall that each time the group
setting is changed, a channel scan is automatically done.
2. Turn on the transmitter and change the group and channel to match the receiver.
3. Leave the transmitter on and continue to the next system.
4. Once all receivers are set up, perform an audio check on all microphones.
Manually Setting Receiver Group and Channel
The receiver group may need to be changed as part of a multiple system setup.
Group (letter)
1. Hold the group button on the receiver until the display begins to flash.
2. While the display is flashing, press the group button again to advance to the next group.
Note: Only the group setting will be displayed during the manual setup.
3. Once the desired group is reached, release the group button. The receiver automatically performs a channel
scan.
Channel (number)
Always use a channel selected by the channel scan. However, if necessary, the channel can be set manually. Fol­
low the same steps above using the channel button instead of the group button.
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, two­way radios, computers, media play­
ers, Wi-Fi devices, and digital signal processors
• Charge or replace the transmitter battery
• Keep transmitters more than two meters (6 feet) apart
10/24
Shure Incorporated
• 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 pres­
ence, 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.
11/24
Shure Incorporated
Adjusting Gain
Monitor the audio meter on the receiver display when setting the transmitter gain. The OL indicator should only illu­
minate 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.
