1.后面板连接dbx DriveRack PA后面板如图1所示。其主要功能如下。(1)电源连接器:工作电压范围为100~120 V/50~60 Hz,包括一根IEC电源线。(2)输出1~6:输出部分提供6个电子平衡的XLR连接器。(3)输入1~2:输入部分提供2个电子平衡的XLR连接器。(4)+4/-10 dB开关:开关改变的电平范围,或者是+4 dBv,或者是-10 dBv。(5)接地脱开开关:接地脱开开关使两个输入XLR
1. Back Panel Connections The dbx DriveRack PA back panel is shown in Figure 1. Its main function is as follows. (1) Power Connector: The working voltage range is 100 ~ 120 V / 50 ~ 60 Hz, including one IEC power cord. (2) Output 1 ~ 6: The output section provides 6 electronically balanced XLR connectors. (3) Input 1 ~ 2: The input section provides two electronically balanced XLR connectors. (4) + 4 / -10 dB switch: The level at which the switch changes, either +4 dBv or -10 dBv. (5) Ground disconnect switch: The ground disconnect switch allows two inputs to the XLR
