The utility model relates to a preceding-stage
effector, belongs to the technical field of sound effect
processing devices, and particularly relates to a preceding-stage
effector capable of switching functions, which comprises a shell, a
front panel is fixed on one side of the shell, and a mounting plate is arranged in the shell; according to the utility model, through the cooperation among the audio input interface, the audio output interface, the
signal detection module, the
mode switching module, the audio
processing module and the
microprocessor, audio
processing parameters and functions can be automatically adjusted according to different use scenes, and through a built-in intelligent
identification system and a preset mode, the audio processing parameters and functions can be automatically adjusted. The type of an input
signal can be automatically detected, a corresponding mode is switched, and optimal sound effect processing is provided; through the arrangement of the mounting
assembly, the movement of the mounting plate is conveniently controlled, so that when maintenance and cleaning are needed, the mounting plate is pulled out to be exposed outside, and the operation is convenient; the problems that an existing preceding-stage
effector cannot conduct function switching and is inconvenient to clean and overhaul are solved.
