*For alkaline batteries only. For rechargeable batteries, solid red means the batteries are dead.
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 proceeds to channel
scan.
Note: If you want to stop the scan, push the group or channel
button.
2. Turn on transmitter and change the group and channel to match the
receiver (See Manually Setting Group and Channel).
Once the receiver is set up, perform an audio check on the
microphone.

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 dis-
played during the manual setup.
3. Once the desired group is reached, release
the group button. Then the receiver will au-
tomatically perform a channel scan.

If channel needs to be changed, follow the
same procedure using the channel button
instead of the group button.

Transmitter Setup
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 ready LED on receiver illuminates.
Multiple System Setup
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 is 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. For
the BLX88, be sure to setup both transmitters before progressing to the next receiver.
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.
Before you begin system set up, turn all receivers ON and all transmitters OFF.
For the first receiver:
1. Perform a group scan.
This finds the group with the most clear channels.
Note: For the BLX88, the group scan sets up both receivers at the same time.
2. Turn on the first transmitter and change the group and channel to match receiver.
3. Leave the transmitter on and continue with the additional systems.
For each additional receiver:
1. Use manual setup to 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.
Locking and Unlocking Controls
Lock system controls to prevent accidental setting changes or power off.
Transmitter
Turn the transmitter on. Hold the group button, then
press the channel button for approximately 2 seconds.
The LED indicator rapidly flashes amber when locked and
green when unlocked.
Receiver
Turn the receiver on. Simultaneously press the group
and channel button to lock or unlock. The display flashes
rapidly.
When locked, the LED display flashes rapidly if any key
is pressed.
The BLX88 can be locked from either side for both sides.

Wireless Tips to Improve System Performance
If you encounter wireless interference or dropouts, try the following suggestions:
• Replace the transmitter batteries
• Choose a different frequency channel
• Reposition the antennas 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, and
digital signal processors
• Keep transmitters more than two meters (6 feet) apart
• Keep the transmitter and receiver more than 5 meters (16 feet) apart
• Keep them away from large metal objects
• 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 microhpone 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).
BLX1
Use the thumb wheel on the inside of the bodypack bat-
terydoortoadjustthegainup(+)ordown(−)untildesired
level is reached. For instruments, turn gain to minimum
setting. For lavaliers, increase the gain as desired. The
audio LEDs on the receiver should illuminate when you
speak into the microphone or play your instrument. The
red LED should only illuminate infrequently when you
speak loudly or play your instrument loudly.
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
LEDdisplay,whichindicates−10dBgainsettinghas
been activated.
2. To change the gain back to default, hold the channel
button again for 5 seconds, or until the dot disappears.

Expected life for AA batteries is up to 14 hours (total
battery life varies depending upon battery type and
manufacturer).
When the LED indicator turns red, it signifies "low battery"
with approximately 60 minutes of remaining battery life.
For alkaline batteries only. For rechargeable batteries,
solid red means the batteries are dead.
To remove batteries from the handheld transmitter, push
them out through the opening in the microphone battery
compartment.
WARNING: Danger of explosion if battery
incorrectly replaced. Operate only with Shure
compatible batteries.
WARNING: Battery packs shall not be exposed
to excessive heat such as sunshine, fire, or
the like.
Wearing the Bodypack
Transmitter
Clip the transmitter to a belt or slide a guitar strap through
the transmitter clip as shown.
For best results, the belt should be pressed against the
base of the clip.
Power Off
Hold down the power button to power off the BLX2 or
BLX4/88. To power off the BLX1, slide the power toggle
switch to OFF.
Removing and Installing
Identification Caps
The BLX2 is equipped with a black identification cap from
the factory (dual vocal systems comes with a black and
gray cap).
To remove: Remove battery cover. Squeeze sides and
pull off cap.
To install: Make sure the tab matches the slot on the bot-
tom of the handheld and click into place. Replace battery
cover.
An optional Identification Cap Kit containing 9 colored
caps is available (see Optional Accessories).
