Front-Of-House 观众席 - PRESONUS StudioLive III Series Owner's Manual

13.7.1 Front-of-House 观众席
In small venues where the guitar amp and the drum kit can be clearly heard over the
Main Front-of-House system, an output delay can"move back" the Front-of-House
system to the backline. This will sharpen the attack of the instruments and prevent
phasing issues.
在小型场地中，吉他音箱和鼓组可以通过主前厅系统清楚地听到，输出延迟
可以将前厅系统 "移回 "到后线。这将加强乐器的攻击，防止相位问题。
In large venues that push the limits of the Front-of-House system's coverage, using
delay speakers distributed throughout the room, each delayed to the main system,
allows you to create listening zones for more even coverage and better intelligibility.
在大型场馆中，如果将前厅系统的覆盖范围推向极限，使用分布在整个房间的
延迟扬声器，每个延迟到主系统，可以让你创建聆听区域，以实现更均匀的覆
盖和更好的可懂性。
Sound travels at a rate of 1,130 feet per second (with some variation due to
temperature, humidity, and elevation). Therefore, it takes 1.1 ms for sound to travel
one foot. For example, it takes about 11 ms for sound to travel 10 feet. So if you are
aligning your Front-of-House system is 10 feet from your drum kit, you need to delay
the signal going to that system by 11 ms.
声音以每秒1130英尺的速度传播（由于温度、湿度和海拔的不同，会有一些
变化）。因此，声音传播一英尺需要1.1毫秒。例如，声音传播10英尺需要大
约11毫秒。如果你要把前厅系统对准离你的鼓组10英尺的地方，你需要把进
入该系统的信号延迟11毫秒。
There are professional software products that can calculate the exact alignment
times, but with a little math and little careful listening, this can be dialed in without
extra accessories.
有专业的软件产品可以计算出准确的对准时间，但只要稍加计算和仔细聆听
，就可以拨出这个时间，不需要额外的配件。
In a small venue with a relatively small stage, both the main speaker system and the
acoustic level of guitar amps and the drum kit on stage can be heard by listeners
in the audience. This can reduce the intelligibility of the speaker system because,
for example, the mic'd snare signal and the acoustic snare signal are arriving at the
listener's ear at different times. This is where output delays come in.
在一个舞台相对较小的场地，主扬声器系统和舞台上的吉他放大器和鼓组的声
学水平都可以被观众听到。这可能会降低扬声器系统的清晰度，因为，例如，
麦克风的小鼓信号和原声小鼓信号在不同的时间到达听众的耳朵。这就是输出
延时的作用。
The first thing you will need to do is to find the loudest instrument on the stage. In
general, this is the snare drum, but it could be the guitar amp, so let your ears do the
deciding.
你 需 要 做 的 第 一 件 事 是 找 到 舞 台 上 最 响 的 乐 器 。 一 般 来 说 ， 这 是 小 鼓
， 但 也 可 能 是 吉 他 音 箱 ， 所 以 让 你 的 耳 朵 来 决 定 。
1. Measure the distance from the snare drum to the mid-frequency drivers of your
main Front-of-House system and divide it by 1.1 (if measured in feet) or 0.34 (if
measured in meters).
测量从小鼓到主观众席系统的中频驱动器的距离，然后除以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 Main mix and set the Output delay to the
result of your calculation.
在StudioLive混音器上，选择主混音，将输出延迟设置为计算结果。
3. Bring up the level of the snare channel on your mixer to unity and have your
drummer play single hits on the snare, about one hit every second. Make sure he
or she plays at the level they will play during the performance.
将调音台上的小鼓通道的电平调到统一，让你的鼓手在小鼓上进行单击，
大约每秒钟击打一次。确保他或她的演奏水平，与他们在演出时的水平一
致。
