A-2係列產品是我司工程師經長期研發、實踐而開發的一款體積緊湊、高聲壓級、寬角度可變調整覆蓋角度號角的線性、矩陣相結合的高效（多形式）演出音箱，其最大的特點就是高音清晰明亮，中音飽滿圓潤，低音強勁有力，聲壓級高，人聲還原度高，滿足了對人聲高還原度，高聲壓級要求的環境場合使用。並可以作為線陣或矩陣音箱使用。

例如1、作為矩陣垂直使用時，根據箱體自身的角度可以並列2-4隻組合使用，根據箱體的特殊掛吊及配套矩陣吊架，可以吊裝使用及固定安裝使用（如大型禮堂、劇院的中置擴聲係統）。

2、作為小型活動使用時，可以根據音箱底部的支架底座使用音箱支架將音箱支起或固定在超低音箱的上麵即可。（減少了因其他音箱自身箱體過大、指向性、覆蓋角、現場固定安裝等無法解決的問題，可以按常規音箱操作使用）。

3、作為戶外線性演出音箱使用時，將號角旋轉90度，利用音箱自帶的線性吊掛件及配套吊掛的田子架組成4-8隻線性音箱使用。

此音箱適用於體育館,禮堂,劇院.DISCO.夜總會,戶外中小型演出等娛樂場所.

配合使用A-18.M-218等超低頻箱組合在一起使用,會有更好的音場效果.

            A - 2 series products are our engineer after long-term research and development, the practice and development of A compact volume, non-linearity, adjust the Angle of cover wide Angle variable linear matrix, and combine the horn efficient speakers (form) performance, its biggest characteristic is the high clear and bright, alto full fruity, bass strong, high sound pressure level, vocals, reductive degree is high, meets the voices of high degree of reduction, environmental situations required by the non-linearity.And can be used as a line array speaker or matrix.
 
            For example 1, vertical when used as matrix, according to the Angle of the body itself can be tied for 2-4 only combination, according to the special hung nooses and supporting matrix of casing hanger, can use lifting and fixed installation (such as the large hall, theatre sound reinforcement system of).
 
           2, when used as a small activity, can according to use speakers sound box at the bottom of the base bracket will sound box set up or fixed on the top of the ultra-low sound box.(reduced by other speakers own cabinet is too large, directivity, covering fixed Angle, field installation cannot solve the problem, can according to the conventional speakers operation).
 
          3, used as outdoor linear performance speakers, horn will rotate 90 degrees, use speakers with linear crane accessories and supporting way of hanging frame of four to eight linear speakers use only.
 
         This box is applicable to the gymnasium, auditorium, theater. DISCO. Nightclub, outdoor entertainment such as small and medium-sized performances.
 
          Used A-18. M - 218 such as ultra-low frequency box used together, can have a better sound effect.
