Independent gain range switching key is to facilitate the different needs. Due to the building structure, there is different frequencies in the different propagation characteristics, that is closely related to the objective volume and material displays in each venue. Having the different frequencies in the different materials of the reflection and sound absorption,which need the equalizer resulting in the uneven transmission characteristics of the venue, and even produced a result of standing wave feedback and howling. 規(guī)格參數(shù)： FrequencyRespones頻率范圍（ /-0.5dB） 20Hz-20KHz Noise (unweighted)信噪比 ＞100dB ChannelSeparation分離度 ＞50dB InputImpedance輸入阻抗 40KΩ OutputImpedance輸出阻抗 100Ω PowerSupply供電電源 220V/AC/50Hz PowerConsumption耗電量 20VA Dimensions外型尺寸（W H D） 482 88 130mm Weight重量 2.9kg
