Interactive operation interface instructions
The main interface 1 to 8 input channels and the main output channel, press“CH9-16”to switch to 9-16
channel, press “AUX”switch to the auxiliary output channel.
Input channel function:
1.INPUT EQ:4 band PEQ,BAND1 and BAND4 can be set between the shelf and clock shape.
Can adjust frequency, gain and Q value within the range.

3
Up and down drag frequency adjustment gain, Gain range:-15dB~15dB
Up and down drag frequency adjustment frequency, Frequency range: 20Hz~20KHz
Q value: Adjust audio curve slope.
HPF: High-pass filter, the high frequency signal can be normally passed, and lower than the
threshold value of low frequency signal is blocked, weakened.
LPF: low-pass filter, the low frequency signal can be normally passed, and higher than the
threshold value of low frequency signal is blocked, weakened.
Presets: Can use preset effects.
Reset : Reset parameter
Polarity: Phase inversion
2.PAN: L/R PAN adjustment, adjust the distribution of sound source in space, such as adjust to the
left, put the sound source to the left channel.
3.Gate and Compressor:
Gate:The system sets a level threshold, if higher threshold the level signal will be amplified, lower
threshold the level input signal level will be reduced. Usually use to eliminate background noise
when no music signal input.
Threshold: Set the value of the threshold (critical levels), -60 dB~0 dB.
Start: When the input signal exceeds the threshold value, the time require to open the compressor,
settable range:1ms-250ms
Recovery: when the input signal is lower than the threshold value, the time require to shut down the
compressor. settable range:20ms-250ms.

4
Compressor: It’s a kind of amplifier with the input signal level increase and its own
gain reduction.
Threshold: Set the compressor threshold value (critical level), -60 dB~0 dB.
Start: When the input signal exceeds the threshold value, the time require to open the
compressor, settable range: 1ms-250 ms.
Recovery: When the input signal is lower than the threshold value, the time require to shut
down the compressor. settable range:20ms-250ms .
Ratio: Compression ratio 1:1 to 1:10, the greater the compression ratio, the smaller the
compression margin, the smaller the compression ratio, the greater the compression
margin.
4.Matrix: By using the principle of the matrix, adjust the channel source to the aux output level..

5
5.Input channel fader: Adjustable range -60 dB~10 dB.
6.Mute: Mute switch, click the button to close the channel audio input.
7.Solo: monitor switch, click on this button, you can use headphones to hear the sound signal before
the channel fader
8.Channel name: click on this button, allows to edit name or select an image to identify the channel.
Group:Set 4 Mute Group and 4 Control Group.
Mute Group: After entering mute edit interface, as picture shows: after click“mute 1”select1,3,6,8
channel，and then click mute group“1”,so 1 ,3,6,8 channels are in the same mute group.

7
Control group: After entering control edit interface, as picture shows: after click
“control 1 ”,select 1,2,3,4 channel, and then select the simultaneous adjustment
function that you want, then click control group”1”, so that you can adjust the
parameters of 1,2,3,4 channel at the same time.

8
48V:Independently control 16 input channel’s 48V phantom power on/off. Which channel
requires 48V power supply, you lit the corresponding channel icon on.
CLEAN MUTE: Click on this button, after 2 seconds, all channel mute function is deleted.
CLEAN SOLO : Click on this button, after 2 seconds, all channel monitor function is deleted.

EFFECT：REVERB and ECHO
Effect (reverb): It’s function is to change the original sound waves, modulate or delay acoustic
phase, enhance harmonic properties, etc, to produce a variety of special sound effects. Apply
across the sound effect(effects, impacts).
Delay(1、2、3、4）：the time that the sound back to ear after reflection, range:30ms-100ms. 4
bands of delay group make the sound superposition effect more exquisite.
Reverb time: reverb effect lasting time, setting range: 0.1S~10S
LPF:low-pass filter, setting range is 20Hz~20000Hz.
Reverb with preset save function ，reset parameter function, input level, output level control
and mute switch function.

10
Delay(ECHO)：Delay is ECHO effects producer.
Delay Left: Control the interval time of the left channel echo, range is 10ms-1000ms.
Delay Right: Control the interval time of the right channel echo, range is 10ms-1000ms.
The longer the delay time is, the longer the duration of the echo is, until you can clearly hear
the sound of double or multiple.
Feedback amplitude: Feedback rate of ECHO effect, set the range (0%~100%), control ECHO
times, feedback rate is 0%, is actually the reverberation effect, feedback rate is 100%, will form
the endless ECHO effect. So ECHO effect is generally controlled at around 30%.

11
LPF：
Main output channel function:
1.Output EQ:
31-band GEQ, can adjust the frequency for compensating the defect of loudspeaker and
acoustic. Click “DRAW ”, so you can drag the frequency range ball-balancing effect of the
drawing you want to.

12
2. PAN: L/R PAN
3. Main output compressor:
You can set a level point, once the signal exceeds the critical point will be attenuated volume, so
that the overall volume stable, to avoid howling or overload loudspeakers.

13
Threshold: Set the compressor threshold value (critical level),-60 dB~0 dB.
Start: When the input signal exceeds the threshold value, the time require to open the
compressor, settable range: 1ms-250ms.
Recovery: when the input signal is lower than the threshold value, the time require to shut
down the compressor, settable range: 20ms-250ms .
Ratio: compression ratio 1:1 to 1:10, the greater the compression ratio, the smaller the margin
compression, the smaller the compression ratio, the greater the margin compression.
4.Main output channel fader: Adjustable range -60 dB~10 dB.
5.Mute: Mute switch for controlling main output
6.Channel name: click on this button, allows edit a name or select an image to identify the
channel.
