What to do if my D.A.S. AERO-12A has no sound and the SIGNAL LED is off?
- D
  David PalmerAug 3, 2025
  If there is no sound and the SIGNAL LED is not lit, it could be due to several reasons. First, ensure that the mixer or sound source is actually sending a signal to the unit. Second, check the cable connecting the sound source to the unit, ensuring it's properly connected; replace it if you suspect it's defective. Finally, the amplifier may have overheated; allow it to cool down for a few minutes. Also, verify the main output level of the mixer or channel gains to prevent future overheating due to excessive levels.

Why is my D.A.S. AERO-12A Speaker System not reaching full power, and the LIMIT LED never illuminates?
- K
  Keith AndersonAug 9, 2025
  If your speaker system isn't reaching full power and the LIMIT LED remains off, the issue might be that the signal source's output isn't strong enough. If you're using a mixer, try using the balanced output if available. Consider using a professional mixer with a stronger output.

What to do if my D.A.S. Speaker System's ON LED doesn't light up?

  Yolanda RuizAug 15, 2025
  If the ON LED doesn't illuminate when the speaker is connected to mains and switched on, begin by checking the AC connection to the unit and the mains outlet for any looseness or issues. Next, inspect the AC cable for faults, using a mains tester to check cables and connectors. If these steps don't resolve the issue, replace the fuse with another of the same type and size. If the mains voltage is out of range, you may need the assistance of an electrician to find an appropriate solution.

Why does my D.A.S. AERO-12A sound distorted?
- E
  Elizabeth CrossAug 21, 2025
  Distorted sound from your speaker system can stem from a couple of issues. Check if the mixer or signal source itself is distorting; if so, reduce the mixer channel gains. Alternatively, the system might be overloaded, having reached its maximum power. In that case, lower the mixer's output level.

What causes hum or buzz in my D.A.S. Speaker System when using lighting controls?
- D
  davisdawnAug 27, 2025
  Hum or buzz when using lighting controls can be caused by a couple of things. The audio signal cable may be too long or too close to the lighting cable, so move the audio signal cable away from lighting cables and try to find out at what point the noise is leaking into the system. If you're using a three-phase AC system, the lighting equipment and the unit might be connected to the same phase; if so, connect the sound system to a different phase than the lights. You may need the help of an electrician.
