Setup

Proper setup ensures optimal performance and safety for your EUROLIVE B112D speaker.

1. Placement

• Stand Mounting: The B112D features a standard 35-mm pole socket for mounting on a speaker stand. Ensure the stand is stable and rated for the speaker's weight (approximately 27.1 lbs / 12.3 kg).
• Floor Monitor: The trapezoidal design allows the speaker to be tilted on its side for use as a floor monitor. Position it securely to prevent accidental movement.
• Tabletop: For smaller applications, the speaker can be placed on a stable, flat surface.

2. Power Connection

1. Ensure the speaker's power switch is in the "OFF" position.
2. Connect the supplied power cable to the AC inlet on the rear panel of the speaker.
3. Plug the other end of the power cable into a grounded AC power outlet.

3. Audio Connections

The B112D features a 2-channel mixer with various input options:

• Mic/Line Inputs (XLR/TRS Combo Jacks): Connect microphones or line-level sources (e.g., mixers, instruments with preamps) to these inputs. Use XLR cables for microphones and either XLR or 1/4" TRS cables for line-level signals.
• Wireless Receiver (USB Port): For wireless operation, connect a Behringer ULM digital wireless receiver (sold separately) to the dedicated USB port. Refer to the ULM system's manual for pairing instructions.
• Line Output (XLR): Use this output to link additional active speakers or send the mixed signal to another audio device.

Important: Always make sure all connections are secure before powering on the speaker.

Operating Instructions

Follow these steps for safe and effective operation of your EUROLIVE B112D speaker.

1. Power On/Off Sequence

1. Before powering on, ensure all volume controls on the speaker and connected devices are set to their minimum levels.
2. Power on your audio source (mixer, instrument, etc.) first.
3. Flip the power switch on the rear of the B112D to the "ON" position. The power LED will illuminate.
4. When powering off, reverse the sequence: turn off the B112D first, then your audio source. This prevents pops and thumps.

2. Adjusting Volume and EQ

• Gain Controls: Each input channel has a dedicated gain control. Adjust these to achieve a healthy signal level without clipping. The "Clip" LED will light up if the signal is too hot; reduce the gain until it no longer illuminates.
• Main Volume: The main volume control adjusts the overall output level of the speaker. Start low and gradually increase to the desired listening level.
• EQ Controls (Bass/Treble): Use the Bass and Treble controls to fine-tune the speaker's frequency response to suit your environment and audio material. A flat setting (center position) is a good starting point.

3. Wireless Operation (with ULM System)

If using a Behringer ULM digital wireless system:

1. Connect the ULM receiver to the USB port on the B112D.
2. Power on the ULM transmitter (microphone or bodypack).
3. The speaker will automatically detect the wireless signal. Adjust the wireless input level using the dedicated control on the B112D.
4. Refer to your ULM system's manual for detailed pairing and operation instructions.

Maintenance

Regular maintenance helps prolong the life and performance of your speaker system.

• Cleaning: Clean the exterior of the speaker with a soft, dry cloth. Do not use abrasive cleaners, solvents, or waxes. Avoid spraying liquids directly onto the speaker.
• Ventilation: Ensure that the ventilation openings are clear and not obstructed. Adequate airflow is crucial for preventing overheating.
• Storage: When not in use for extended periods, store the speaker in a cool, dry place, away from direct sunlight and extreme temperatures. Consider using a protective cover to prevent dust accumulation.
• Inspection: Periodically check the power cable and audio cables for any signs of damage. Replace damaged cables immediately.

Caution: There are no user-serviceable parts inside the speaker. Refer all servicing to qualified service personnel.
