一旦你定位延时系统，测量从左前方的扬声器到最近的延时扬声器（很可
能是左侧的延时扬声器）的距离。用这个距离除以1.1（如果以英尺计算
）或0.34（如果以米计算）。
2. On your StudioLive mixer, select the FlexMix driving the output connected to
your left side delay speaker and configure it as a Subgroup.
在StudioLive混音器上，选择驱动连接到左侧延迟扬声器输出的FlexMix，
并将其配置为子群。
3. Set the Output delay on your newly created subgroup to the result of
your calculation.
将新创建的subgroup 输出延迟设置为计算结果。
4. Repeat steps 1-3 with the right side of the system.
在系统的右边重复步骤1-3。
5. Once you have positioned and delayed your satellite system, use an SPL
meter to match the output of the main and delay systems at the measurement
point. For example, if you are standing 30 feet from the left side of the main
system and 10 feet from the left side of the delay system, and the output of the
main system is 85 dB, then the output of the delay system should also be 85 dB.
一旦你已经定位和延迟你的卫星系统，使用SPL计来匹配主系统和延迟系
统在测量点的输出。例如，如果你站在离主系统左侧30英尺，离延迟系统
左侧10英尺，主系统的输出是85分贝，那么延迟系统的输出也应该是85分
贝。
It should be noted that frequencies in the sub-bass range of a delay system do not
require distribution. In fact, a delay system's high pass filter should be rolled up as
high as 300 to 400 Hz to avoid sound going back toward the stage as low
frequencies become omnidirectional.
应该注意的是，延迟系统的次低音范围内的频率不需要分配。事实上，
延时系统的高通滤波器，应该卷起到300到400赫兹，以避免声音在低频
变得全向的时候，向舞台回流。
