1、This series of products is a karaoke effector with the function of speaker processor, each part of the function can be adjusted independently.

2、This machine adopts high-efficiency toroidal transformer power supply to ensure that the sound is thick and mellow.

3, MUSIC input channel is equipped with 15-band parametric equalization, with high and low-pass adjustment, a variety of slopes can be selected, variable tuning function, input left and right channel parametric equalization can choose to adjust independently or jointly.

4, 2 groups of MIC input, MIC1 for group A, MIC2 for group B, before and after the microphone each 15-band parametric EQ independent adjustment, each group has a high, low-pass adjustment, a variety of slopes can be selected, open microphone noise gate, the user can freely choose, microphone channel has a variable tuning function.

5, the main output, rear output, auxiliary output 1, auxiliary output 2, are equipped with 10-band parametric equalization, and high and low pass can be adjusted arbitrarily, a variety of slopes can be selected, the main output and rear output of the left and right channels of the parametric equalization can be selected to adjust independently or jointly adjusted. Auxiliary output 1 and auxiliary output 2 can be used as ultra-low, not subject to the high and low pass control of the music input channel.

6, the main output, rear output, auxiliary output 1, auxiliary output 2 can be arbitrarily set to: singing, hot dance or automatic mode

7, reverb and echo are equipped with 5-band parametric equalization.

8, each channel output is equipped with 0 to 50ms delay.

9, the microphone has 8 levels of feedback suppression.

10, the main output, rear output, auxiliary output 1, auxiliary output 2 are equipped with limiting function, limiting the signal in the large dynamic input, very good protection of the sound system, and will not affect the sound quality, easy to use.

11, can store 13 modes. 14,15,16 three modes for the factory mode, can only call, can not be saved.

Every time you turn on the machine is mode 1, call mode, all parameters together.

12, the machine is equipped with all-round function menu, can also be set through the PC interface, the machine can be connected to the computer through the data line or WIFI connection.

13, the machine PC interface installation-free, driver-free

14, the machine has a 3-layer engineering lock and PC connectivity password lock function, when the machine panel lock, PC interface connectivity must enter the key lock password to connect to the machine.

15, CK4620 + music and microphone AD input using PCM1804, 6-channel output DA using PCM1798, and 6-channel output using a true balanced output, the entire sound field dynamics.

16, the machine uses 56-bit DSP chip, 48KHz sampling frequency, 24bitADC/DAC converter.

17, delay adjustment minimum 0.1 milliseconds of adjustment step, so that the adjustment is more accurate.

18, crossover filter types include: Butterworth (Butterworth), Bessel (Bessel), Linkwitz-Riley (Linkwitz-Riley), the slope of the maximum support for 24dB/Oct

19, you can set the running time of the device.

20, option type lock setting, support for external central control protocol.

21, the machine comes with a USB sound card function, you can play the music in the computer through the machine's USB cable.

22, each output channel of the machine has a spectrum display, can better monitor the status of the machine when used, and can change the type of spectrum display.

23, music IN2 for the XLR balanced port input, small distortion, anti-interference ability.
