3. Link Speakers (Optional): If connecting multiple speakers, use an XLR cable to connect the LINK OUT of the first speaker to an INPUT of the next speaker.
4. Connect Power: Ensure the speaker's power switch is in the OFF position. Connect the provided power cable to the IEC power inlet on the speaker and then to a grounded AC power outlet.
5. Power On: Turn on your audio source first, then switch the power button on the Montarbo FIRE 12A MK2 to the ON position.

6. Operating

Once set up, follow these guidelines for operation:

• Volume Adjustment: Start with the MAIN VOLUME and individual INPUT VOLUME controls set to their minimum positions. Gradually increase the input volume of your audio source, then slowly raise the MAIN VOLUME on the speaker to achieve the desired listening level.
• Signal Indicators: Observe any signal or clip indicators on the speaker. If the clip indicator illuminates frequently or stays on, reduce the input volume to prevent distortion and potential damage.
• Power Off Sequence: When finished, first turn down the MAIN VOLUME on the speaker, then switch the speaker's power OFF. Finally, turn off your audio source.

Proper maintenance ensures the longevity and performance of your speaker:

• Cleaning: Use a soft, dry cloth to clean the exterior of the speaker. Do not use abrasive cleaners, solvents, or waxes.
