Shure Incorporated BLX Wireless System System Components Note: Your system comes with a combination of the following components.
Shure Incorporated 3. 1. Install batteries and turn on transmitter. 2. 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.

Shure Incorporated 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. 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 Chan nel).
Shure Incorporated 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.
Shure Incorporated Locking and Unlocking Controls Lock system controls to prevent accidental setting changes or power off. Transmitter (lock/unlock) Turn the transmitter on. Hold the group button, then press the channel button for approximately 2 seconds. The LED indicator rapidly flashes red when locked. Receiver (lock/unlock) Turn the receiver on. Simultaneously hold the group and channel button. The display flashes rapidly. • When locked, the display flashes rapidly if any key is pressed.
Shure Incorporated 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 micro phone.
Shure Incorporated 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 decrease (−) the gain until desired level is reached. For instruments, turn gain to minimum setting. For lavaliers, increase the gain as desired.
Shure Incorporated 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 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 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.
