HOLLYWOOD SOUND GOES INDIE
ZOOM又发布了一款影视制作用的录音机，这次直指独立电影，口号是HOLLYWOOD SOUND GOES INDIE-好莱坞声音走进独立片。
F4这款产品可以算是ZOOM F8的简化版，自F8去年10月上市以来，已经销售万台，可以说创造了影视录音产品销售历史的奇迹。同样，F4以低廉的价格，超高的性能来占领市场，正如官方所说：“电影制作从未像现在一样形成一种浪潮，感谢负担的起的技术及网络分销渠道的发展，我们正迎来一个新的时代，而这一切仅仅是开始”
下面我们来看看这款ZOOM F4的具体硬件配置。支持8轨道/6输入的现场录音和混音。它们的接口和我们所喜欢的F8的接口尺寸大小一样，但ZOOM F4与类似产品Nagra 7或Sound Devices 744T的性能更好，并且价格更低。
F8、F4的特点是非常低噪音的麦克前置放大器，增益输入在-127到+75分贝之间；线路电平输入是+4分贝。输入5和6可以作为一个监控，连接摄像机返送，同时可通过TONE来进行音量检查。
Zoom还增加可设置的板载限制器为所有四个通道的输入，这使得它的声音录制更加完美或有一个意想不到的尖叫（惊喜）也能保持完美。记录采用广播WAV格式（BWF），16位或24位Bit，采样率高达192千赫。也有MP3录音选项128，192，或320 kbps。在双通道记录模式下，您可以在输入1和2上创建备份安全轨道，它具有独立的水平，延迟，高通滤波，限制和相位反转的功能。
F4有两个平衡XLR的主输出和一个小三芯的子输出，一个大三芯监听接口可用专用的音量旋钮控制。
F4让你更惊讶的是什么，是你在这个价位所得到的最精准的时码器，即使同品质的单独时码器也需要这个价格。F4采用的Temperature Compensated Crystal Oscillator (TCXO)，可以在23.976ND, 24ND, 25ND, 29.97ND, 29.97D, 30ND and 30D上，具有0.2ppm的精准度。
重量大约为1kg（无电池），双SD卡插槽，支持多种录音模式。它们还额外添加了一个安全设置，F4在记录的时候可以定期保存文件。你可以拿出SD卡传输文件或使用USB端口来备份。当然，同F8一样，F4还可以作为一个6-in/4-out采样率高达96 kHz的USB音频接口。
