Embodiment 1
[0045] The sound system of the method for calibrating a professional sound system for a stage or film and television in this embodiment includes a plurality of active speakers, and this embodiment adopts the active speakers as described below.
[0046] Such as figure 1 As shown, the active sound box includes a signal input unit 11, a digital signal processor 12, a plurality of power amplifier units 13 and a plurality of speaker units 14, each power amplifier unit 13 is connected with a matching speaker unit 14, and the speaker unit 14 can be composed of a or multiple speakers. The signal input unit 11 is used to receive the audio signal input from the speaker and transmit it to the digital signal processor 12 .
[0047] Such as figure 2 As shown, the digital signal processor 12 is provided with a data storage module 124, and the data storage module 124 stores a group of input processing parameters and multiple groups of output processing parameters corresponding to each pow...
Embodiment 2
[0118] The difference between this embodiment and Embodiment 1 is that in the step S43: if the entity DSP data corresponding to the virtual DSP data includes speaker layer DSP parameters and array layer DSP parameters, then according to the modified virtual DSP data, the corresponding The microprocessor of the active speaker sends a control signal for modifying the corresponding entity DSP data, and the microprocessor modifies the corresponding DSP parameters in the corresponding entity DSP data according to the DSP parameters in the virtual DSP data included in the control signal;
[0119] If the physical DSP data corresponding to the virtual DSP data only contains the DSP parameters of the speaker layer, a new DSP parameter is obtained by superimposing and calculating the DSP parameters of each layer of the virtual DSP data, and then the modification is sent to the microprocessor corresponding to the active speaker Corresponding to the control signal of the physical DSP data,...
