Page 27: Audio Input Module
2.2 Audio input module The interface can display 8 channels at most, which can be switched by pressing key; click the channel to switch the above functional module display box. See 2.1.2.3 for the channel information. Different colors of the channel represent different types of input channels. For example, the 14-16 channel shown in the figure above represents the simulated input channel of the device, 17-18 channel represents the USB playback channel, and 1-3 channel represents the Dante input channel The input channel supports grouping function, and multiple channels can set to a group.
Page 28: Input Source
2.2.1 Input source The sensitivity of MIC input and line input can be selected. High sensitivity indicates high acoustic-electric conversion efficiency of the MIC, and sensitive reflection of weak voice signal; Allow call: allow the access of panel signal to the channel. Down indicates access, and up indicates access is not allowed.
Page 29: Exp/Gate
2.2.2 Exp/Gate The expander will add dynamic range to the input according to needs of the user. When the signal input is less than “threshold”, the expander amplifies and outputs the signal input by the “ratio” set. Level output = threshold – (threshold – level input)/ratio; when the signal input is more than “threshold”, it is output by 1:1.
Page 30 2.2.3 EQ The equalizer is used to compensate and modify the frequency characteristics, so that it can achieve the characteristic of relatively flat frequency response Different models of equalizers are of different types, and the specific type shall be subject to the actual model of the device. 5 band paragraph EQ The equalizer is to compensate and correct the frequency characteristics to make it reach a true and straight frequency response characteristic.
Page 31: Compress
2.2.4 Compress The compressor is to compress the signal by the preset ratio when input signal level more than threshold. When the input level is more than the preset threshold, the output level is compressed by the ratio set. Signal Output = Threshold + (Signal Input - Threshold) / Ratio; if the input level is less than preset threshold, the signal will be directly output.
Page 32: Agc
2.2.5 AGC First, the function of AGC is described. For example, when the user speaks facing towards the microphone, the distance between the mouth and the microphone will fluctuate, causing fluctuating volume output. Though setting the threshold, AGC outputs the signal input by 1:1 if the level less than threshold while the level over the threshold will be directly raised by ratio.
Page 33: Auto Mixer
2.3 Auto Mixer In the meeting room, 10 microphones, if 10 microphones are open and have the same level, and only one person in the speech cause the remaining 9 microphones will pick up the room noise, reverberation sound, affect the audio quality. Secondly, because of these standby microphones, the effective acoustic components of the maximum gain before the sound feedback would relatively decline and cause volume inadequacy.
Page 34: Gating Automixer
Channel mute and fader are automatic gain type, i.e., no matter how you act; there is no effect on automatic mixer. It means that a particular channel is silent, if the high level signal on the channel is present, the remaining channels’ level would also reduce. In order to mute a signal and prevent the signal effect automatic mixing, please open the mute and turn “AUTO”...
Page 35 speech signal exceeds the threshold, the channel gates on and the signal passes. If the background noise floor changes, the threshold updates in real time. 1) channel control Indicator light: When the channel is selected by auto mix and turned on, the indicator light is on.
Page 36 higher gain. The difference between the channels is one difference per unit, and the gain is different by 2dB (assuming the priority step value is set at 2.0). For example, the priority of channel 1 is set to 6 and the priority of channel 2 is set to 3. When the two channels receive the same level of signal, the gain of channel 1 is higher than the gain of channel 2 by 6dB.
Page 37: Feedback Canceller
2.4 Feedback Canceller AFC Feedback Canceller can auto-detect and suppress sound’ s feedback. It can distinguish voice and feedback clearly. When the feedback is detected, the module will add a notch filter and reduce the feedback frequency. Filter Oct: there are four kind of mode in the list, they are “Conference 1”, “Conference 2”, “Music 1”and“Music 2”...
Page 38: Aec
2.5 AEC Set the echo to be processed through the feedback canceller, and the signal processed can be output in "from" of the output part. Proximal end input: the signal input from local MIC and requiring echo processing. Remote input: reference signal.
Page 39: Audio Output Module
2.6 Audio output module The interface can display 8 channels at most, which can be switched by pressing key; click the channel to switch the above functional module display box. See 2.1.2.3 for the channel information. According to the different colors of the channel, different types of the output channel are respectively represented.
Page 40: From
2.6.1 From Select the input signal from which the output channel signal are taken. If more than one signals are selected, then the signal are superimposed for output. 2.6.2 Speaker Manager (1) EQ There are 8 bands for output parameter equalizer and each band can individually adjust center frequency, gain and Q value (bandwidth) to reinforce or weaken the signal in some bands and accordingly to achieve different effects.
Page 41 Flatten All : restore all bands to the status at 0 dB. Band Bypass: after adjusting EQ, a user can cancel the bypass which has been set for some bands. A user can restore a band to the status at 0 dB by selecting the corresponding button to that band. Bypass can only affect the band and cannot affect others.
Page 42: Limiter
2.6.3 Limiter The limiter is to limit the signal more than threshold. When the signal input is more than threshold, the signal output is equal to threshold. When the signal input is less than threshold, the signal output is equal to the signal input. Bypass: The signal input is bypassed and not be processed.
