    A COMPRESSOR SYSTEM WITH EQ
    TECHNICAL FIELD
    The invention generally relates to technology field of equipment and system for audio signal processing, especially relates to a compressor system with EQ.
    BACKGROUND
    With the development of entertainment and media industry, consumers become more sensitive to the quality of sound quality. In the venue, theater, concert and home theater and other application occasion of audio player equipment, requirement for audio adjust function of audio processing system is getting higher and higher.
    In the technosphere of audio mixer, equalizer and compressor has been widely used in the process of audio signal. With the combined application of equalizer and compressor, modulation distortion of D-class power amplifier can be controlled during the maximum power output, and maximum output can also be adjusted. In the application of DSP, the compressor is series connected to the equalizer, input signal is input to the equalizer for processing then delivered to compressor for compressing and limiting, and received by the signal output device. Generally, only one threshold is setup in the compressor during the application above, and the threshold is a constant value for full-brand audio signal. However, as the voltage output corresponding to each frequency is different, it leads to the result that trigger threshold for volume is different. Bandwidth of compressor triggered is getting larger and larger with the volume of each frequency is increasing. When the volumes of each frequency are larger than the threshold, output signal line’s shape becomes flat, and it can’t reach the effect of audio adjustment.
    SUMMARY
    The model utility provide a compressor system with EQ. In the system, electrical level threshold of full-band audio signal is setup in the compressor, and the value of electrical level of the input signal is detected by the signal detection module. After comparison of electrical level threshold and the value of electrical level, it determines the compressor is triggered to work or not. It can achieve the technology efficacy that audio signal of different frequency is compressed and limited effectively.

    BRIEF DESCRIPTION OF THE DRAWINGS
    1. FIG. 1 is a principle diagram of a compressor system with EQ in accordance with an embodiment of the utility model.
    2. FIG. 2 is a working sketch of a compressor system with EQ in accordance with an embodiment of the utility model.
    DETAILED DESCRIPTION
    In order to fully comprehend the features and efficacy of the present utility model, a detailed description is described by the following substantial embodiments in conjunction with the accompanying drawings. The description is as below.
    Referring to FIG.1 , it is an principle diagram of a compressor system with EQ in accordance with an embodiment of the utility model. The utility model provides a compressor system with EQ. The system comprises a signal input device 1, an equalizer 2, a compressor 3 and a signal output device 4, and the compressor 3 includes a signal detection module 31.
    The signal input device 1, such as CD or DVD, send out two-way input signal to compressor 3 parallelly, that is input signal a and input signal b. Signal a is identical to input signal b. Expressed differently, the compressor 3 is configured to receive the first input signal a and the second input signal b simultaneously. For example, in the frequency of 180Hz, both of the electric levels of input signal a and input signal b are 5dB. However, input signal a is input to the compressor 3 directly, while input signal b is adjusted with signal gain by the equalizer 2 then input to the compressor 3 in the form of
    DK 2016 00632 A1 input signal b1, and detected by the signal detection module 31. The function of equalizer is to adjust the value of signal gain or attenuation of every frequency. In this embodiment, the value of electric level of input signal b is 5dB, and after attenuation processing (-5dB) adjusted by equalizer 2, the value of electric level of input signal b1 is only OdB. Then input signal b1 is input to compressor 3.
    Now referring to FIG.2, different electrical levels threshold of full-band audio signal whose range is 20 Hz ~ 20 kHz are setup in the compressor 3.In the embodiment, electrical level threshold of 180Hz is setup as 5dB. The value of electric level of input signal b1(0dB) is compared to the electrical level threshold(5dB).As the value of electric level of input signal b1(0dB) is less than the electrical level threshold(5dB), the compressor(3) isn’t triggered to compress and limit the input signal a. And input signal a is still output to the signal output device in the form of output signal a.
    If the tuner enhances both of the electrical level of input signal a and input signal b from 5dB to 10dB in the frequency of 180Hz. Input signal b is attenuated (-5dB) by the equalizer 2, then is input to the compressor 3 in the form of input signal b1 (5dB). In the compressor 3, electrical level threshold of 180Hz is still 5dB.Now the value of electric level of input signal b1(5dB) is equal to the electrical level threshold(5dB).lt lead to the result that the compressor(3) is triggered to compress and limit the input signal a. And input signal a is output to the signal output device in the form of output signal a1.
    To further describe the signal output device 4, it includes at least one of the soundbox, loudspeaker or headset. After processed by the compressor system, audio signal is received by the signal output device 4 with the characteristic of high fidelity and controllability. On account of the features, it meets the requirement of audio signal adjustment and achieves a wide range of application in audio signal processing.
    For ease of illustration, electric level threshold of full-band audio signal is setup as a constant value in the compressor normally. When every frequency point’s volume is greater than the electric level threshold, the curve of output signal is close to a straight line without the trigger processing by the compressor. It doesn’t achieve the efficacy of audio signal’s adjustment.
    The present utility model is disclosed by the preferred embodiment in the aforementioned description; however, it is contemplated for one skilled at the art that the embodiments are applied only foran illustration of the present utility model rather than are interpreted as a limitation for the scope of the present utility model. It should be noted that the various substantial alternation or replacement equivalent to these
    DK 2016 00632 A1 embodiments shall be considered as being covered within the scope of the present utility model. Therefore, the protection scope of the present utility model shall be defined by the claims.
