1. For convenience, we often divide dynamic range into two more specific ranges: signal-to-noise ratio and headroom.
    为了方便，我们经常把动态范围分成两个更小的范围：信噪比和headroom。

2. \u0039\u0031\u0031\u67E5\u8BE2\u00B7\u82F1\u8BED\u5355\u8BCD

2. They are the ideal choice when high headroom and low distortion are needed, especially when reproducing the dynamic range and clarity of today''s digital recordings.
    他们是理想的选择空间和高时低失真是必需的，尤其是音响的动态范围和当今的数码录音清晰。

3. Full power – simple flexibilityFour state-of-the-art stereo amplifiers with separate LEVEL controls and displays give the POWERPLAY PRO plenty of dynamic headroom.
    功率强大，灵活简明POWERPLAY PRO 拥有 4 个最先进的立体声功放，配有独立的输出电平控制钮和电平显示，动态余量充裕。

4. The number and output power of power amplifier should be put to match the sound module and leave a certain dynamic headroom to avoid clipping to put the protection of the sound module and the other back-up unit should be deployed.
    功率放大器的数量和输出功率应和放音单元相匹配并留有一定动态余量，避免削波，以保护放音单元，另应配置一定的备用单元。
