FAQs
Q: What type of speakers can I connect to this amplifier?
Passive speakers with an impedance of 4 to 8 ohms can be connected. To avoid overloading or damaging the amplifier, be sure that each channel’s total load impedance does not go below 4 ohms.
Q: What is the output power of the AA0520?
The amplifier ensures clear and powerful audio performance throughout the frequency spectrum by delivering 2 x 120W RMS @ 4Ω or roughly 2 x 80W RMS @ 8Ω.
Q: Can I use this amplifier with an active (powered) speaker?
No, the AA0520 is solely intended to power passive speakers. It could harm both devices if connected to powered speakers.
Q: How do I adjust volume levels properly?
To get the required volume, gradually raise the input and output levels after starting both volume controls at minimum. To avoid distortion or overheating, avoid operating the amplifier at maximum power for extended periods of time.
Q: Does the AA0520 have a cooling fan?
Indeed. To maintain safe operating temperatures, the machine has an integrated ventilation system and cooling fan. When using the vents, make sure they are unobstructed.
Q: Can I connect multiple input devices at the same time?
Yes, but to prevent signal interference or overloading the input stage, only one input source should be active at a time. To securely swap sources, use the input selector switch if it is available.
Q: What protection features does the amplifier have?
Overload, short-circuit, and heat safety circuits are all included in the AA0520. In order to prevent harm, the unit will immediately shut down or mute the output if it senses a defect.
