Operating Instructions

Powering On/Off:

Ensure all connections are secure before powering on. Flip the POWER switch on the rear panel to the ON position. To power off, flip the switch to the OFF position.

Adjusting Sound:

The B112D features an integrated mixer with dedicated controls:

• Volume Control: Use the LEVEL knob to adjust the overall input volume. Monitor the CLIP LED to ensure the signal is not distorting (red indicates clipping).
• 2-Band EQ: Utilize the HIGH and LOW equalizer knobs to fine-tune the sound. Adjust these to achieve the desired tonal balance for your audio.

Using the Wireless Option:

The EUROLIVE B112D is ready for use with Behringer's ULTRALINK ULM series wireless microphones. Refer to the ULM series manual for detailed instructions on pairing and operation.

Linking Multiple Speakers:

For larger venues or stereo setups, connect the LINK OUTPUT XLR connector of one B112D speaker to the input of another active speaker. This allows for easy daisy-chaining of multiple units.

Maintenance

To ensure the longevity and optimal performance of your Behringer EUROLIVE B112D, follow these maintenance guidelines:

• Cleaning: Regularly wipe the exterior with a soft, dry cloth. Avoid using abrasive cleaners or solvents.
• Storage: Store the speaker in a cool, dry environment away from direct sunlight and extreme temperatures.
• Inspection: Periodically check all cables and connections for wear or damage.

Troubleshooting

If you encounter issues with your EUROLIVE B112D, refer to the following common troubleshooting steps:

• No Power: Ensure the power cord is securely connected to both the speaker and a working power outlet. Check the power switch position and any external circuit breakers.
• No Sound: Verify that the input source is active and sending a signal. Check all audio cable connections. Ensure the LEVEL knob on the speaker is turned up and not muted.
• Distorted Sound: Reduce the input volume from your source device and/or the LEVEL knob on the speaker. If the CLIP LED is red, the signal is too high. Check for damaged cables.
