Install batteries and turn on transmitter.

On the transmitter, set the group and channel to match the receiver. The audio LED on the receiver should illu

minate.

If setting up additional systems, leave the first transmitter and receiver on. For each additional receiver, manual

ly set the group to match the first receiver. Note: The receiver will automatically perform a channel scan to find

an available frequency after the group has been selected. Set the transmitter frequency to match the receiver.

If sound is too faint or distorted, adjust the gain accordingly.

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.

Press and release the button on the receiver.group

The receiver scans for the clearest group and channel.

Note: If you want to stop the scan, push the group button again.

Turn on transmitter and change the group and channel to match the receiver (See Setting Transmitter Group and Chan

nel).

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)

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 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. For the BLX88, be sure to setup both transmitters before progressing to the

next receiver.

Turn any other equipment that could cause interference during the performance so it will be detected during the group and channel scans in the following on

steps.

Before you begin system set up, turn all receivers and all transmitters .ON OFF

For the first receiver:

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.

Turn on the first transmitter and change the group and channel to match receiver.

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:

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.

Turn on the transmitter and change the group and channel to match the receiver.

Leave the transmitter on and continue to the next system.

Once all receivers are set up, perform an audio check on all microphones.

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

Green: normal levels

Red: excessive sound levels (overload).

The red LED should only illuminate infrequently when you speak loudly or play your instrument loudly.

The BLX2 features two gain level settings, default and attenuated (-10 dB). The default setting is used for most situations. If the

receiver LED flickers red often, set the microphone to attenuated. Use the button to change the gain setting.audio channel

Hold down the button for 5 seconds.channel

A dot appears on the lower righthand corner of the LED display, which indicates −10 dB gain setting has been activat

ed.

To change the gain back to default, hold the button again for 5 seconds, or until the dot disappears.channel

Batteries

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.

Shure Incorporated

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 button to power off the BLX2 or BLX4/88. To power off the BLX1, slide the power toggle switch to OFF.power

Removing and Installing Identification Caps

The BLX2 is equipped with a black identification cap from the factory (dual vocal systems ship with additional gray cap).

To remove: Remove battery cover. Squeeze sides and pull off cap.

To install: Align the cap and click into place. Replace battery cover.

An Identification Cap Kit containing assorted colored caps is available as an optional accessory.
