2. Uppsetning
- Upptaka: Fjarlægðu varlega ampFjarlægið úðann úr umbúðunum. Geymið öll umbúðaefni til síðari flutnings eða geymslu.
- Staðsetning: Settu ampSetjið hitagjafann á stöðugan, sléttan flöt. Tryggið næga loftræstingu í kringum tækið til að koma í veg fyrir ofhitnun. Forðist að setja það nálægt hitagjöfum eða í beinu sólarljósi.
- Rafmagnstenging: Tryggðu að amplifier's power switch is in the 'OFF' position. Connect the supplied power cord to the amplifier's IEC inlet on the rear panel and then to a suitable grounded AC power outlet. The AS50D operates on 220-240V ~ 50Hz or 120V ~ 60Hz depending on the region.
- Upphafleg tengsl:
- For acoustic guitars or other instruments, connect a standard 1/4" (6.35mm) instrument cable from your instrument to the 'Input' jack of 'Acoustic Channel 1'.
- For microphones, connect an XLR cable from your microphone to the 'Microphone Input' of 'Microphone / Aux Channel 2'.
- For external audio devices like MP3 players or drum machines, connect them to the 'Aux Input' RCA phono jacks on 'Microphone / Aux Channel 2'.
- Kveikt á: Once all connections are secure, switch the amplifier's power switch to the 'ON' position. The power indicator light will illuminate.

5. Bilanagreining
- Enginn kraftur:
- Athugaðu hvort rafmagnssnúran sé vel tengd bæði við amprafmagnara og innstunguna.
- Gakktu úr skugga um að innstungan sé virk.
- Tryggðu að amplifier's power switch is in the 'ON' position.
- Ekkert hljóð:
- Check all instrument and microphone cables for secure connections and proper functionality.
- Ensure the 'Volume' controls for the active channel and the 'Master Volume' are turned up.
- Verify that your instrument or microphone is working correctly.
- Distortion at High Volumes:
- Reduce the 'Volume' control for the active channel or the 'Master Volume'.
- Ensure your input signal is not too strong. Adjust the output level of your instrument if possible.
- Check the quality of your instrument cables; faulty cables can introduce noise and distortion.
- Feedback (Howling Sound):
- Engage the 'Anti-Feedback Notch' switch.
- Slowly rotate the 'Anti-Feedback Frequency' knob to find and eliminate the problematic frequency.
- Reduce the 'Volume' of the affected channel or the 'Master Volume'.
- Move further away from the amplifier or change your position relative to the speakers.
