SP-600 is a four-microphone omnidirectional microphone speaker with intelligent DSP, with adaptive echo suppression (AEC) algorithm, which can process remote echo. The unique DRC technology can intelligently amplify the sound with low sensitivity in the distance by a maximum of about 10 times without affecting the performance of echo suppression. Even if the other party's sensitivity is high, the sound can be amplified by about 2 times to ensure both parties Listening effect. The 6-meter pickup radius is intelligently adjusted by the algorithm to achieve a sound pickup isobaric effect, which can easily cope with the pickup demand in an environment of about 120 square meters. In addition, the SP-600 also has adaptive algorithms such as voice enhancement, automatic gain control (AGC), and adaptive input gain (AGC), which can automatically adjust the pickup volume according to the preset maximum gain target value to ensure a stable sound Output.
