What Are The Differences Among Stereo, Parallel Input And Bridge Mono Modes - QSC DCA1222 User Manual

FEATURES & SETUP
What are the differences among Stereo, Parallel
Input, and Bridge Mono modes?
Stereo mode
This is the "normal" way of using the amplifi er, in which each channel is fully
independent. Separate signals connect at the inputs, the gain knobs control
their respective channels, and separate speakers connect to each output.
Examples:
• Two-channel (stereo) or multi-channel playback.
• Bi-amped operation, with the low frequencies in Channel 1 (or 3) and the
highs in Channel 2 (or 4).
Parallel input mode
This mode is just like Stereo mode, except that the inputs for Channels 1 and 2
or 3 and 4 are internally connected together. A signal into any input jack will
therefore drive both channels directly. Each channel's gain control still func-
tions as usual, and each channel feeds its own speaker load.
You can patch the input signal on to additional amplifi ers by using any of the
remaining input jacks.
Example:
• One surround channel signal driving both channels, with independent gain
control for each speaker system.
功能与设置
立体声、并行输入或桥式单声操作模式之间有
何区别？
立体声模式
这是使用放大器的"标准"方式，在该方式中每个声道都完全独
立。各种信号在输入端处连接，增益旋钮控制它们各自的声道，
各个扬声器连接至各个输出端。
示例：
• 双声道（立体声）或多声道播放。
• 双放大器操作，声道 1（或 3）使用低频，声道 2（或 4）使
用高频。
并行输入模式
此模式类似于立体声模式，但声道 1 和声道 2 或者声道 3 和 4
的输入端是内部相连。一个进入任何输入插孔的信号因此将直接
驱动两个声道。每个声道的增益控制器仍像往常一样工作，并且
每个声道输送其各自的扬声器负载。
您可以使用剩下输入插孔中的任一个，将输入信号添加到其他放
大器中。
示例：
• 一个环绕声道信号驱动两个声道，每个扬声器系统都具有独立
的增益控制器。
