扩声过程中,如何获得高保真,对扩声工作人员来讲,正确地了解它们间所接受、传递的阻抗、电平、动态线性等等,从而进行合理的设备匹配,是十分必要的。一、电平传输方式的匹配目前国内生产制造的各种扩声设备其电平传输方式共有两种:①平衡式,②单端式。见图1所示。
In the process of sound reinforcement, how to obtain high fidelity is very necessary for the sound reinforcement staff to correctly understand the impedance, level, dynamic linearity, etc. which are accepted among them, so as to perform reasonable equipment matching. First, the matching level transmission At present, the domestic production of a variety of sound reinforcement equipment, there are two levels of transmission: ① balanced, ② single-ended. See Figure 1 below.
