Extron DA AV EQ 系列为高性能分配放大器，用于在长距离电缆传输过程中，分配并传输复合视频、S- 视频及音频信号，同时维持信号源的质量与强度。该系列置于耐用且结构紧凑的半机架金属机箱内，很容易与新的或现有的视听系统集成。
Extron DA AV EQ 系列包括七个复合视频* 与音频信号分配放大器。八个型号拥有150 MHz (-3dB) 的满载视频信号带宽，其增益调整功能用于补偿在长距离电缆传输过程中产生的信号衰减，均衡调节功能则补偿高频损耗。所有视频型号与NTSC、PAL 和SECAM 视频信号兼容，传输电缆长度为180 米至300 米甚至更远。输入环通能力让用户能添加更多放大器，以创建更大的 DA 系统或驱动本地监视器。
