Introduction
介绍
Thank you for purchasing the PreSonus® PRM1 RTA
Microphone. This omnidirectional microphone has been
designed to provide an accurate reproduction of a room's
sound characteristics for use with audio-analysis tools, such as
real-time analyzers and spectrographs. Delivering a flat
frequency response from 20 Hz to 20 kHz and featuring a ¼",
pre-polarized, electret condenser capsule, the PRM1 is an
excellent companion to the Virtual StudioLive™ Smaart® System
Check Wizards and other analysis systems. We appreciate the
support you have shown us through the purchase of this
product.
感谢你购买 PreSonus PRM1 RTA 麦克风。这种全向麦克风的设计是
为了准确再现房间的声音特性，以便与音频分析工具（如实时分析
仪和光谱仪）一起使用。PRM1 在20 Hz 到20kHz之间，提供平坦的
频率响应，并具有1/4英寸、预偏振、驻极体电容麦克风头，是
Virtual StudioLive™ Smaart®系统检查向导和其他分析系统的最佳伴
侣。我们感谢你，通过购买该产品对我们的支持。

About This Microphone
关于此款麦克风
The PRM1 is a condenser microphone with a flat frequency
response and an omnidirectional polar pattern. Let's briefly
define these terms.
PRM1是一个具有平坦频率响应和全指向高精度声学测试麦
克风。让我们简单地定义一下这些术语。
Condenser Microphones
电容式麦克风
Condenser microphones such as the PRM1 require a power
source, which can be provided by an external power supply or
using phantom power, which is usually provided by a mixer,
preamplifier, or direct box. Phantom power is sent over the
same mic cable that carries the audio signal; the term derives
from the fact that there is no visible power cable, and the
voltage is not perceptible in the audio path.
像PRM1这样的电容式麦克风需要一个电源，可以由外部电
源提供，也可以使用幻象电源，这通常由调音台、前置放大
器或引导盒提供。幻象电源是通过传输音频信号的同一根麦
克风电缆发送的；实际这个术语是，即没有可见的电源电缆，
而且电压在音频路径中，也是无法感知的。
PreSonus StudioLive-series mixers provide phantom power to
every mic input, including the talkback input utilized by the
Smaart System Check Wizards in VSL.
PreSonus StudioLive系列调音台为每个麦克风输入提供幻象
电源，包括VSL中 Smaart 系统检查向导所使用的对讲输入。
Flat Frequency Response
平坦的频率响应
A microphone with a flat frequency response captures all
frequencies equally within its specified response range, neither
boosting nor cutting frequencies, so it accurately reproduces
the incoming signal. While this makes it ideal for measuring
what a room or speaker is doing to the outgoing signal in a
sound system, it is not necessarily the best choice for recording
specific instruments.
具有平坦频率响应的传声器，在其指定的响应范围内平等地
捕捉所有频率，既不提升也不削减频率，因此它准确地再现
了传入信号。虽然这使它成为测量房间或扬声器，对音响系
统中传出信号的理想选择，但它不一定是录制特定乐器的最
佳选择。
Omnidirectional
全指向性
The PRM1 has an omnidirectional polar pattern, meaning it is
equally sensitive in all directions. This allows the microphone to
measure reflections, as well as direct signals, providing an
accurate depiction of the room.
PRM1有一个全向的极性模式，这意味着它在所有方向上都
同样敏感。这使传声器能够测量反射以及直接信号，提供一
个准确的房间描述。
