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.
