| 摘要 |
This utility model relates to a universal interface for enabling an auxiliary input in any sound system, comprising: at least one amplifier (AMP) connected to the universal auxiliary input, a commutator arranged upstream of the signal outputs for the loudspeakers, and a control device consisting of a push button, a switch, and an MP3 decoder or similar, which activates the commutator, determining whether the output sound is the sound from the original system or the sound from the auxiliary input. The interface for enabling the auxiliary audio input has a means for modifying the amplified sound signal from an original audio apparatus (OEM), which converts same into a less powerful signal, adapting it to the range of power admissible by the sound input of the amplifier of the auxiliary input, the signal commutator in this case being arranged upstream of the amplifier of the universal auxiliary input, which sends it to the loudspeakers of the sound system. |
