Save scene: Save the current running parameters to the selected scene. d. Save as: Save the currently running parameters to the PC in a scene. e. - Page 11 Invert: The signal phase is processed by 180 degrees. Phantom power supply: used for condenser microphone power supply, please do not turn on line input or non-condenser microphone to prevent burnt; Test signal: including sine, pink, and white noise. Enabling the test signal system will automatically shield the analog input signal;...
- Page 12 4.3 Compressor The compressor is used to reduce the dynamic range of the signal above a user-defined threshold. The signal level below the threshold remains unchanged. Threshold: When the signal level is higher than the threshold, the gain will be reduced. This point is the inflection point in the input/output curve.
- Page 13 4.4 Equalizer Parameter equalization Pass-through/enable: Whether the equalizer is valid. Band Pass-through/enable: Whether the section equalizer is valid. Center frequency: the center frequency that needs to be equalized. Gain: Gain/attenuation value at the frequency center point. Bandwidth: the influence range of this segment around the center frequency. The larger the value, the larger the bandwidth and the larger the influence range.
- Page 14 4.5 Auto gain The purpose of automatic gain control is to achieve the target level of signals with uncertain levels while maintaining the dynamic range of the volume. Typical usage scenarios: For example, when the user is speaking in front of the microphone, the distance between the mouth and the microphone may be too far and near, which causes the output volume to fluctuate and even feel intermittent in speech.
- Page 15 4.6 Auto Mixer The automatic mixer is mainly used to automatically control how the traditional mixer has a large amount of voice input to output the desired result. Consider a typical conference room scene. There are ten participants, each with a microphone.
- Page 16 4.7 Auto Mixing/AFC/AEC/ANC Feedback: Select the signal to be processed by the feedback canceller, and select the output channel of the processed signal in the mixer. Auto mix: Mix the signal of the selected input channel to the corresponding output channel. AM: Signal processed by the automatic mixer AFC: Signal processed by feedback canceller AEC: Signal processed by echo canceller...
- Page 17 4.9 Frequency Divider High frequency pass/enable: enable and disable the high pass filter. Low frequency pass/enable: enable and disable the low pass filter. High-pass frequency: the cut-off frequency of high-pass filtering. Low-pass frequency: the cut-off frequency of low-pass filtering. 4.10 Limiter Through/Enable: Enable or disable the limiter.
