The invention relates to a sound box control technology, in particular to a calibration method for a stage, film and television professional audio system. This method solves the multi-layer adjustable problem at the system level by using active speakers with array layer DSP parameters (specifically speakers with frequency division above 2), and introducing speaker models to virtualize multi-layer DSP parameters. Models to achieve synchronous adjustment of each speaker model of the array group. All in all, this technology can not only simplify the difficulty of audio system debugging and calibration, reduce the workload, but also ensure better sound effects during system debugging.

The invention relates to a sound box control technology, in particular to a method for debugging a speaker system. The method comprises a step of establishing a speaker system model, a step of modifying virtual input processing parameters and a step of modifying virtual output processing parameters, wherein the speaker system model comprises a plurality of sound box models; each sound box model corresponds to one entity speaker and comprises the virtual input processing parameters and the virtual output processing parameters; the virtual input processing parameters comprise one or a plurality of pieces of virtual DSP (Digital Signal Processor) data; and each piece of DSP data comprises a plurality of layers of DSP parameters which belong to the same type. Therefore, no matter how many layers of DSP parameters each entity DSP data of each active speaker comprises, the multilayer adjustment of the input processing parameters of system layers can be implemented by the technology, so that the debugging and correcting operation of the speaker system is simplified, the debugging efficiency is improved and the debugging effect of the system is ensured.

The invention relates to sound box control technology, in particular to a control method of an active sound box with a built-in DSP. The method comprises: S10, adjusting each DSP (digital signal processor) parameter of a DSP according to an external control signal; S20, receiving an audio signal inputted from outside of the sound box, and transmitting to the DSP; S30, the DSP executing a plurality of signal processing operation steps in an assembly line manner; and S40, the power amplifier unit receiving the corresponding output audio signal processed by step S40, and transmitting to the corresponding speaker unit. The control method provided by the invention can simplify the difficulty in debugging and calibrating the sound box system by setting the array layer DSP parameters for synchronously adjusting the plurality of sound boxes, thereby reducing the work load, and ensuring the system debugging effect.

The invention relates to sound box control technology, in particular to an active sound box and a speaker system calibration method. The active sound box comprises a signal input unit, a digital signal processor, a plurality of power amplifier units and a plurality of speaker units, wherein each power amplifier unit is connected with the matching speaker unit; array layer DSP (digital signal processor) parameters are set in the digital signal processor to simplify the work load for debugging and calibrating the speaker system so as to ensure the debugging result of the speaker system. The calibration method is executed for the speaker system consisting of the active sound boxes, and can simplify the complexity degree and the work load for system debugging by synchronously controlling the plurality of active sound boxes through the array layer DSP parameters without precisely debugging each active sound box by the conventional method, thereby greatly improving the debugging and calibration efficiency.
