特点:
■ 标准机箱设计,2U铝合金面板;人性化的抽手设计,美观实用。
■ 2路线路(AUX1、2)输入,每一通道均可独立调节音量。
■ 1路线路输出可以接纯后级功放以扩展功率。
■ 3路话筒输入(MIC1、2、3);第一话筒(MIC1)具有最高优先,有强切入优先功能。每一通道均可独立调节音量。
■ 带默音调节旋钮,可调节默音深度。
■ MIC 2、3通道附设有线路信号辅助输入接口功能
■ 2路紧急输入线路具有二级优先,强行切入优先功能
■ 设有高音(TREBLE)和低音(BASS)独立调节。
■ 采用场效应管前级放大,传统的变压器三极管推挽线路,音色清秀、纯净。
■ 内置2级有源高通滤波和低通滤波器,自动消波还原信号;拥有完整的线路安全工作保证。
■ 机器异常工作保护警告功能:当输入信号过大、负载过重、线路短路时,对应的指示灯闪烁提示,有极高的可靠性。
■ 完善的温度保护:大电流高速风扇,工作噪音低,散热效果佳;当机器温度升高时,温度保护电路会启动风扇;风扇的转速随温度的升高而自动提高。
■ 2种功率输出方式:定压输出100V,70V;定阻输出4~16Ω。
可选配故障检测模块,实现故障检测短路信号输出,可扩展实现主备功放自动切换功能
