LED Indicator | Status |
Green | Ready |
Rapidly Flashing Red | Controls locked |
Solid Red | Battery power low (less than 1 hour remaining*) |
Flashing Red and shuts off | Batteries dead (change batteries to power on transmitter) |
*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.
Transmitter group and channel must be manually set to match the receiver.
If channel needs to be changed, follow the same procedure using the channel button instead of the group button.
Note:
Up to 12 systems can operate simultaneously (band and RF environment dependent).
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.
Before you begin system set up, turn all receivers ON and all transmitters OFF.
For the first receiver:
Note: If the selected group does not contain enough open channels, manually select group "d" when setting up larger systems.
For each additional receiver:
The receiver group may need to be changed as part of a multiple system setup.
Always use a channel selected by the channel scan. However, if necessary, the channel can be set manually. Follow the same steps above using the channel button instead of the group button.
If you encounter interference or dropouts, try the following suggestions:
Monitor the audio meter on the receiver display when setting the transmitter gain. The OL indicator should only illuminate infrequently when you speak loudly or play your instrument loudly.
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.
The BLX2 features two gain level settings:
Use the default setting for most situations. If the receiver audio OL indicator displays often, set the microphone to -10 dB.
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.
Danger of explosion if incorrect battery replaced. Operate only with AA batteries.
Battery packs shall not be exposed to excessive heat such as sunshine, fire, or the like.
Lock system controls to prevent accidental setting changes or power-off.
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.
Turn the receiver on. Simultaneously hold the group and channel button until the flashing lock icon appears in the lower left-hand corner of the display, indicating the controls are locked. Repeat to unlock the controls.
Press and hold the power button to power off the BLX2 or BLX4R. To power off the BLX1, slide the power switch to OFF.
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.
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.
Use the supplied mounting hardware to install the receiver in a standard 19" audio equipment rack.
