Professional Sound System Solution for Conference Rooms D6643H D5830

2024 Guangzhou DSPPA Audio Co., Ltd.
System Solution Overview

With the expansion of the company scale and the need for business development, the frequency of conference room usage has been increasing. However, in large meetings or training events, the sound transmission effect in the conference room is not ideal, leading to participants being unable to clearly hear the speaker's remarks. Therefore, in order to improve the sound transmission effect in the conference room, we need to formulate a sound reinforcement solution.

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.

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.

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.

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.

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.
