Block Size (Windows only). Sets the buffer size. From this menu, you can set the buffer size from 64 to
8,192 samples. Lowering the buffer size will lower latency, which is the amount of time it takes for your
audio to go from Revelator io44 to the computer and back to your ears; however, this will also increase
performance demands on your computer. In general, you will want to set the buffer size as low as your
system can safely support. If you begin to hear pops, clicks, or distortion in your audio path, try raising
the buffer size. When adjusting the block size, the Safe mode will automatically change to provide the
best performance.
块大小（仅限 Windows）。设置缓冲区的大小。从这个菜单中，你可以设置64到8192个样本的缓冲区
大小。降低缓冲区大小会降低延迟，也就是你的音频从 Revelator io44 到电脑再到你的耳朵所需的时间；
但是，这也会增加对电脑性能的需求。一般来说，你想把缓冲区的大小设置到你的系统可以安全支持的
最低限度。如果你开始听到音频路径中的爆音、咔嗒声或失真，请尝试提高缓冲区大小。当调整块大小
时，安全模式将自动改变，以提供最佳性能。
Power User Tip: Your Revelator io44 features built-in zero-latency monitoring so you can leave your Block Size
high and the performance demands on your computer low. In general, you can use the default block size, but if
you're using an older computer that is having trouble keeping up, go ahead and raise this setting. Experiment to
find what works best for you!
用户提示：你的 Revelator io44 具有内置的零延迟监听功能，所以你可以让你的块大小保持在较高的水平，而
对你的计算机的性能要求较低。一般来说，你可以使用默认的区块大小，但如果你使用的是一台老式计算机，
恐怕难以跟上，请继续提高这一设置。尝试一下，找到最适合你的方法。
Device Mode (macOS only). By default, your Revelator io44 presents itself as a single audio interface
with 8 inputs and 6 outputs. But when you're ready to use the Loopback audio streams to record or route
audio to multiple applications at the same time (like the output of a Skype call to the audio input of your
Facebook Live stream), that's where Multi Mode comes in. In this mode, your Revelator io44 will show up
as 3 different devices on your computer: Revelator IO 44, Revelator IO 44 Stream Mix A, and Revelator
IO 44 Stream Mix B. Each of these devices has 2 inputs and 2 outputs. This is great for applications like
Skype that only allow you to use the first two inputs and outputs of any audio interface. PreSonus recom-
mends that you use Multi mode for the best experience. Note that in Multi mode, sample rate options are
limited to 44.1 kHz or 48 kHz. For more information on how loopback audio works and how to use it for
your podcasts, streams, and more, see the
设备模式（仅限MacOS）。默认情况下，你的 Revelator io44 呈现为一个具有8个输入和6个输出的单一
音频接口。但是，当你准备使用 Loopback 音频流来录制或将音频同时发送到多个应用程序（如Skype
通话的输出到Facebook直播流的音频输入），这就是多模式的作用。在这种模式下，你的 Revelator
io44 将在你的电脑上显示为三个不同的设备。Revelator io44, Revelator io44 Stream Mix A, 和
Revelator io44 Stream Mix B。这些设备中的每一个都有2个输入和2个输出。这对于像Skype，只允许你
使用任意音频接口的前两个输入和输出的应用程序是非常好的。PreSonus 建议你使用Multi模式以获得
最佳体验。请注意，在多重模式下，采样率选项被限制在 44.1kHz或48kHz。关于回环音频如何工作以
及如何将其用于播客、流媒体等方面的更多信息，请参见混合和回环音频部分。
