Audio Conference System
Full automatic high speed feedback suppressor for conference system, conference wire and wireless microphone, complete simplex operation, no need to adjust, simple interface, only input, output, power interface. Easy to use, you can increase the microphone gain by 8-10db without creating a loud noise. Because of the use of floating point DSP digital algorithm, the effect is much more stable than analog frequency shift effect, will not be affected by ambient temperature, humidity, dust and other external effects of frequency shift effect, without debugging, automatically adapt to the acoustic environment. No matter how many microphones are opened, the effect is still excellent, high fidelity, easy reproduction of original sound, intelligent mixing, seamless high-speed conversion.
  • Main functions:
  • Supports 4-channel 6.35 unbalanced input and 1-channel balanced signal input. The 5-channel signal input is suitable for all kinds of signal level input, which greatly increases the flexibility and convenience of using
  • Support the adjustment of signal input volume gain size to facilitate the matching of input of different device levels
  • Support 4-way output, 2-way balanced output and 2-way 6.35 unbalanced output
  • With optional output gain, it is convenient for the device to select input before the mixer or output after the mixer
  • The output is provided with adjustable control keys for high pitch promotion and attenuation, which can well match the speaker to make the human voice better and more prominent
  • Support intelligent air-cooled heat dissipation, increase the air-cooled heat dissipation system for the purpose of making the function run steadily for a long time, effectively guarantee the long-term working stability of the equipment, and avoid the phenomenon of engine crash
  • The control panel of the whole machine is simple and intuitive, with only one key to select the switch between straight signal and anti-scream processing signal, greatly simplifying the system debugging process
  • Completely fool operation, built-in advanced floating point DSP digital algorithm processor automatic tracking to eliminate the noise frequency point
