• Independent sound system suitable for conferences.

  III. Project Configuration

  IV. Product Highlight 1

  IV. Product Highlight 2

Operation Instructions

• Set the input threshold to -48dBFS, and the noise is lower than -48dBFS, which will be directly filtered.

• When the ratio is set to 2, the sound will be sharply reduced according to the ratio, thus suppressing the noise.

• Start time: set to 2ms; Recovery time: set to 2 ms.

  IV. Product Highlight 3

Operation Instructions

• When the low-frequency resonance of the environmental sound field is severe, adjust 120-180 to reduce 2-3dB to reduce the low-frequency sound input.

• Increase 1-2dB at 600-800 to supplement the mid-to-high frequencies of the sound.

• It reduces the turbidity caused by low frequencies and improves the clarity of human voices.

  IV. Product Highlight 4

Operation Instructions

• Set the input threshold to -45dBFS, which is greater than the noise threshold of -48dBFS.

• The target level is set to -15dBFS, that is, the sound is in the range of -45dBFS to -15dBFS, and the ratio is set to 2.

  The sound will be directly promoted according to the ratio, and the output will be stable.

• Startup time: set to 200ms; Recovery time: set to 300ms.

  IV. Product Highlight 5

Operation Instructions

• The automatic button "Auto" of input channels 1 - 5 is selected, indicating that the signal of this channel will be sent to the automatic mixer for processing.

• Priority: 0-10 level. When multiple microphones are turned on to speak at the same time, the microphone used by the leader can be set to have a higher priority, 

  thus giving priority to the sound output.

  V. System Advantages

Long Sound Pickup Distance

• With the support of automatic gain and automatic mixing technology, the microphone's pickup distance is 20-60CM, which can restore

  human voices and make them clear and easy to hear.

• It also ensures no howling, no noise, and no interference at a comfortable pickup distance.

Sleek & Stylish Product Design

• Metal texture, zinc alloy shell, tempered glass inlay, beautiful and durable.

• Specially designed shielded circuits and one-piece zinc alloy shell can effectively suppress various types of electromagnetic interference.
