Tendzone CLEAR K Series - Digital Signal Processor

CLEAR K series is Tendzone cost-effective network DSP. It could be created for conference audio system and suitable for conference rooms, churches, star hotels, auditoriums, conference centers, multi-functional rooms, digital courts and other application. With graphical user interface, clear signal route and multi-type control medias like wall panels and cell phones, K4 does not only presents high-quality sound, but also provides high customer experience with strong compatibility, flexible control and simple operations.

High performance & multi-channels

• Input：4 balanced microphone/line input, with 48V phantom power supply
• Output：4 balanced line output
• 24bit/48KHz outstanding sound quality
• GPIO control port，4 logic input，4 voltage input control（could be connected to potentiometer or CLEAR CV4）4 logic output

Automatic adjustment

• AFC，high-speed floating-point digital algorithm provides feedback suppression for each microphone to prevent the system from squealing
• AGC，Automatic gain control, to ensure smoothing output volume of the sound system and make sure the audiences won’t be affected by variations of the speaker’s distance from the microphone.
• AM，with threshold type and gain sharing type selectable
• AEC，rapid elimination of echo in video conference
• Optimized pre-process gain, with 0,6,30,36,42 dB multi-level adjustment, for MIC and LINE level
