.4 DSP module
4.1 Input Setting
The input signal can be an analog signal or a test signal generated inside the
device. If it is a network version with Dante, it can also be a network
digital signal;
The analog signal can be selected by adjusting the sensitivity to adjust the
input; from -60~0, every 3dB; Mute: the channel is muted when selected;
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;
4.2 Expander
The Expander is a dynamic range of input that increases according to the
user’s requirements. When the input signal is less than “threshold”, the
expander compresses the input signal according to the set “ratio”, output
level = threshold-(threshold-input level)/ratio; when the input signal is
greater than “threshold”, then According to 1:1 output, output level = input
level. Pass-through/Enable: Whether the extender is valid. Ratio: The number
of decibels that the expander input signal changes dynamically/the number of
decibels that the expander output signal changes dynamically. Start-up time:
the time required for an input signal less than the “threshold” of the
expander to enter the expanded state to output according to the set expansion
ratio. Recovery time: The time required for the input signal to return from
the expanded state to the original nonexpanded state.
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. For
peak stop, the threshold that needs to be stopped is just below the peak
level. Ratio: The compression ratio of input and output. Start-up time: Start
with the gain of the compressor to reduce the processing speed. The shorter
the startup time, the greater the instantaneous change of the signal, and the
short-term gain attenuation makes the hearing unsuitable. Release time: The
release time determines the gain change from moment to moment of the
compressor. The quick release time increases the subjective level, while the
slow release time is more useful to keep it under control. Output fader: The
fader can control the output gain of the module. If the compressor reduces the
signal level significantly, the output gain boost may need to maintain the
perceived volume.
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. Graphic equalization
The gain of the 31 band frequency points can be adjusted separately to achieve
the purpose of strengthening or weakening some frequency points and achieve
different effects. Pass-through/Enable: Enable and disable the equalizer.
Gain: The gain/attenuation of the frequency center point. Flat: Restore all
frequency band gains to 0dB state. Narrowband: A kind of bandwidth, the
bandwidth is lower than the ordinary bandwidth.
Normal: Common bandwidth. Broadband: The largest bandwidth.
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. Automatic gain is to set the threshold, output the
input signal below the threshold in a ratio of 1:1, and directly increase the
level above the threshold according to the ratio. After setting the target
level, the sound signal can be output stably. Threshold: When the signal level
is lower than the threshold, the input/output ratio is 1:1. When the signal
level is higher than the threshold, input/output = ratio. Set this threshold
level slightly higher than the noise ratio of your input signal. Target
threshold: the required output signal level. Automatic gain control is to
automatically control the amplitude of the gain by changing the input and
output compression ratio. When a weak signal is input, the signal is amplified
to ensure the strength of the output sound signal; when the input signal
strength reaches a certain level, the signal is compressed
to reduce the sound output amplitude. 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. If ten microphones are turned on at the same time,
only one person is talking, then the output effect is definitely not ideal,
because the other nine microphones pick up Sound insulation of the room,
reverberation, etc., will reduce the output effect of the entire system. Each
channel of the automatic mixer has an input, a gain level meter and an
automatic gain, channel fader, priority, and channel mute. Channel control
Each channel has an “auto” button, press to add this channel to the automatic
mixing. The channel mute and fader are both automatic gain type. To mute a
signal and prevent the signal from entering the automatic mixing, please turn
on “Mute” and cancel “Auto”. The channel fader controls the mixing level and
direct output level of the channel. Priority control PR: Allows channels with
higher priority to surpass channels with lower priority, thereby affecting the
automatic mixing algorithm. The control defines the priority with a value
between 0 (lowest priority) and 10 (highest priority), and the default value
is 5 (standard priority). If the priority of all channels is equal, set the
priority of all channels to 5.
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 ANC: Signal processed by
noise canceller 4.8 Delayer The time interval between the signal input to the
output processor.Generally used to produce reverberation or echo and other
effects, can also be used for the use of large auxiliary speaker processing.
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. Threshold: the starting level of the limiter. When the signal is higher than this limit value, the limiter processing module is started. Recovery time: When the input signal is lower than this setting value, the sound channel will not be closed immediately, and the closing time will be delayed according to this setting value. During this time, as long as there is a signal higher than the “threshold” limit value, the sound channel can continue to be turned on. Compression: The difference between the signal processed by the limiter and the input signal. 4.11 Output Setting You can set the output to mute and invert.
