SR-231Q*2U雙31段1/3倍頻程圖示工程均衡器*內置最新的降噪電路，低噪聲輸出*40Hz的低頻切除濾波器*互補增益控制電路使頻點精確、音色平滑、圓潤*具有平衡XLR及1/4＂TRS端子輸入/輸出*高精密的電容提供精準的頻點設有獨立的高通濾波，低通濾波器，剪除多余的頻率以減輕功率的損耗，獨立的增益范圍切換鍵則方便不同需要。由于建筑結構方面的原因，不同的地場有不同的頻率傳播特性，這跟各場地的客觀體積、材料擺設等有密切關系。不同材料反射和吸聲程度不同而對不同頻率的聲音的反射和吸音也不同，造成場地傳輸特性不均衡，甚至因駐波反饋而產生嘯聲，這就需要均衡器。SR-231Q feature:* 2U Dual 31 rows 1/3 octave graphic equalizer* Built-in updated noise reduction circuit, low-noise output* 40Hz low-frequency cut filter* Complementary gain control circuit to make frequency point accurate, tone smooth and mellow.* Balanced XLR and 1/4 TRS input / output* To provide high-precision capacitance-frequency precise point* The independent high-pass filter, low pass filter cut extra frequency in order to reduce the loss of power. 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.
