1. Sistema overview
En El news, Allí son always 5 microphones placed En front of El leaders. Este es no solo Para backup, pero también forms UN microphone array. Two más microphones son placed symmetrically En front of El sound source UN enhance directivity eliminate noise. Enhance reliability.
Based EN El characteristics y advantages of El microphone array, VISSONIC developed El SONIC series array microphone Sistema De Conferencias.
Microphone array technology integrated microphones proporcionar UN corridor-style feature, que ensures ese speakers can tener high-quality sound En UN wide range of activities. Within Este range, El speaker can move freely, stand, sit, turn su head, move forward without affecting El sound effect. Use El silent touch microphone button UN turn Ello EN o off.
2. Sistema advantages y features
-Keep El desktop clean y tidy, connect El microphone Con UN single line, usted can choose hiding underneath o from El rear of El unidad
-no gooseneck microphone, easy UN pick up, cooperar Con powerful DSP processing host UN prevent howling y realize local sound amplification
-Voice-activated speech, automatically within El pickup range, automatically turns EN El microphone cuando speaking, y automatic Conferencia logic algorithm UN ensure smooth speech y reasonable switching
-El ultra-long pickup distance of 80CM forms UN pickup capsule, que allows El speaker UN move freely flexibly use body language
-All-Digital Red core technology, using CAT5e wiring, profesional RJ45 connection, host Con DANTE protocol output, can ser used Con UN complete set of DANTE protocol audio Sistema debugging UN achieve ideal acoustic effects.
2.1.1 Microphone array
VISSONIC array microphones tener multiple pickup heads UN establish su own pickup channels y ranges. no matter quien es speaking, El sound pressure level remains unchanged, reducing environmental noise y ensuring El acoustic feasibility of local sound reinforcement.
2.1.2 Array microphone technology-corridor characteristics
Larger depth pickup range, no need UN adjust El direction of El gooseneck microphone; El speaking state es muy natural y relaxed, El speaker can turn su head, move closer UN o away from El microphone, stand up y sit down, bow o raise su head, while El sound quality remains basically unchanged.
2.1.3 Built-En DSP processing circuit
VISSONIC's all-Digital Sistema es equipped Con El latest DSP processing circuit, Con AEC, AGC, AFC functions.
AFC adaptive feedback cancellation—independent adaptive feedback cancellation, quickly eliminate howling frequency points
AEC echo cancellation technology—eliminates El echo of remote video Conferencia terminals y remote audio conferences
ANC automatic noise cancellation technology-can identify El noise gate through que human voices pass, y effectively eliminate environmental noise
Cada unidad tiene su own FPGA chip Con 16-band equalization y sensitivity adjustment.
2.1.4 Voice control speech
Automatically within El pickup range, El microphone es automatically turned EN cuando speaking. Different from ordinary threshold voice control, VISSONIC voice control speaks Con automatic Conferencia logic algorithm UN ensure smooth speech y reasonable switching.
2.1.5 IP-based audio Sistema, supporting DANTE protocol
VISSONIC Totalmente Digital Red core technology, UN Red cable connected UN El array microphone, Con POE power supply, y El host Con DANTE audio output, que can ser debugged Con El entire DANTE audio Sistema UN achieve ideal acoustic effects.
2.1.6 Mixed use of wired y wireless meetings
Para multifuncional cumpliendo rooms, training rooms, Conferencia halls, etc... ese often need UN ser changed, El unidad de presidente es generally UN limited fixed installation method. El audience seats below son temporarily increased o reduced according UN needs. EN Este time, El wired y wireless Sistema De Conferencias es mixed. Proporciona great convenience, El wireless unidad hace no need UN ser wired, y can ser placed directly as needed.
2.1.7 HD camera tracking
El Sistema controller tiene su own camera tracking function, que can send codes UN El camera y camera switcher y recorder o seamless matrix UN realize automatic tracking y recording of high-definition cameras.
