Note: The package comes with a 36V/6A power supply, and a larger power supply is required to obtain the maximum output power(for example: purchasing a 48V power supply yourself) Please note: As the A3001 amplifier has an input sensitivity of 0.75V, and given that modern source equipment (preamplifiers/DACs) typically has a high output level of 2V, the signal headroom is limited. When the volume is set above 50%, the amplifier’s overload protection is likely to be triggered. Therefore, to prevent overload, we recommend keeping the volume below 50%.
