   • Muzică: Enhanced for music playback.
   • Vorbire: Tailored for vocal clarity.
   • Sub: Engages a high-pass filter for use with a subwoofer.
4. Controale EQ: Utilize the onboard EQ settings to fine-tune the frequency response to compensate for room acoustics or personal preference.
5. Location Presets: Select presets that optimize performance based on the speaker's physical placement (e.g., stand-mounted, flown, or floor).
6. Monitorizare audio: Play your audio source and adjust the LEVEL and MASTER VOL controls to achieve the desired volume without distortion. Observe the signal/clip indicators to prevent clipping.

6. Întreținere

Regular maintenance helps ensure the longevity and optimal performance of your AIR12 loudspeaker.

• curatenie: Disconnect the power before cleaning. Use a soft, dry cloth to wipe down the exterior of the loudspeaker. Avoid using abrasive cleaners, solvents, or waxes, as these can damage the finish.
• Ventilare: Ensure that all ventilation openings remain clear of dust and debris to prevent overheating.
• Depozitare: When not in use for extended periods, store the loudspeaker in a cool, dry environment, protected from extreme temperatures and humidity.
• Inspecţie: Periodically check all cables and connections for signs of wear or damage. Replace any damaged cables immediately.

7. Depanare

If you encounter issues with your PreSonus AIR12 loudspeaker, refer to the following common troubleshooting steps:

• Fără putere:
  • Ensure the power cord is securely connected to both the loudspeaker and a working electrical outlet.
  • Verificați poziția comutatorului de alimentare.
  • Verify the outlet is supplying power by testing with another device.
• Fără sunet:
  • Check that the input source is active and sending a signal.
  • Ensure all audio cables are correctly connected and not damaged.
  • Verify that the LEVEL controls for the input channels and the MASTER VOL knob are turned up.
  • Confirm that the correct input is selected if applicable (though AIR12 has dedicated inputs).
• Sunet distorsionat:
  • Reduce the input LEVEL and MASTER VOL. If the signal/clip indicator is lighting up frequently, the input signal is too hot.
  • Verificați sursa audio pentru distorsiuni.
  • Ensure speaker cables are not damaged.
• Hissing or Noise:
  • Disconnect all inputs. If the hiss persists, the noise may be internal to the speaker.
  • If the hiss disappears, reconnect inputs one by one to identify the noisy source.
  • Ensure proper grounding of all audio equipment to avoid ground loops. Try using a ground lift adapter if necessary, but only as a temporary diagnostic tool and with caution.
  • Lowering input gain and increasing master volume can sometimes reduce noise floor.
• Supraîncălzire:
  • Ensure adequate airflow around the loudspeaker. Do not block ventilation ports.
  • Reduce the operating volume if the unit feels excessively hot.
