| Set the gain on the Microphone input connector. The gain should be adjusted to suit the output level of the connected audio source. The gain can be tuned in steps of 1 dB. If the gain is set too high, the audio signal will be clipped. If the gain is set too low, the audio signal-to-noise ratio will be degraded; however, this is usually preferable to clipping. Note that unprocessed speech signals typically contain significant level variations, making it very important to allow for sufficient signal headroom. The maximum input level with 0 dB gain depends on the product: -18 dBu (Room Bar, Room Kit, Codec Plus, Room 55, Room 70, Room 55 Dual), 24 dBu (Codec Pro, Room 70 G2). Example: If your microphone has a maximum output level of -44 dBu, and it is connected to a Codec Pro, then you should set the gain to 24 dBu - (-44 dBu) = 68 dB. | 用于设置麦克风输入接口的增益值。增益等级需根据所连接音频源的输出电平进行适配调整，调节步长为 1 dB。若增益设置过高，音频信号会出现削波失真；若增益设置过低，会导致音频信噪比下降，但这种情况通常比削波失真更易接受。需注意，未经处理的语音信号电平波动通常较大，因此预留充足的信号余量至关重要。0 dB 增益下的最大输入电平因产品型号而异：- 部分型号：-18 dBu（Room Bar、Room Kit、Codec Plus、Room 55、Room 70、Room 55 Dual）- 部分型号：24 dBu（Codec Pro、Room 70 G2）示例：若麦克风的最大输出电平为 -44 dBu，且接入 Codec Pro 设备，则增益应设置为 24 dBu - (-44 dBu) = 68 dB。 |

| This command is mainly used for the Presenter and Audience room setup. It's mainly used from Control Hub when setting up the feature. During setup we recommend you add information whether the microphone is facing the stage (presenter) or the audience. This information allows for more accurate automatic switching between the local, remote, and hybrid presenter modes. | 该指令主要用于演讲者 - 听众会议室场景的配置，通常在控制中心（Control Hub）中进行功能设置。配置时建议标注麦克风的朝向（面向演讲台 / 演讲者，或面向听众），该信息可帮助系统更精准地在本地、远程、混合演讲模式之间自动切换。 |
技术细节补充
核心参数说明
增益等级（Level）：步长 1 dB，范围 0-24，本质是对麦克风输入信号的放大倍数。需平衡 “信号强度” 与 “失真风险”，优先避免削波失真（信号过载导致的音质损坏）。
拾音区域（Zone）：1-3 共 3 个分区，用于会议室的声源定位管理，搭配演讲者 / 听众的场景标注，可优化混合会议模式下的音频聚焦效果。
设备专属说明
上述型号中，麦克风 1 默认是内置麦克风，无需额外接线；麦克风 2 及后续接口为外接麦克风接口，需手动配置增益和拾音区域。
