LARK Wireless Microphone——S-Track S TRACK SCIENCE TECHNOLOGY CO., LTD

LARK Wireless Microphone

LARK wireless microphone, mainly oriented to the education industry, is used for sound reinforcement or recording and broadcasting scenarios when teachers are teaching. Based on 2.4G wireless transmission technology, it creates an interference-free lecture environment for teachers, and the device has high performance and stability. Built-in intelligent algorithms such as AFC, AGC, ANS and EQ. It allows the teacher to deliver every word clearly to every student without worrying about loud and soft voices. The microphone used in the program is very small and light to wear; compared to traditional handheld microphones, the microphone allows teachers to free their hands and give full play to body language; compared to far-field microphones, the microphone’s sound quality is better, allowing teachers to move around and pick up a wider range of sound.
A set of LARK microphones includes a charging compartment, a transmitter and a receiver. The charging compartment can quickly recharge the transmitter, and the receiver supports both USB Audio Card digital output and two analog outputs.

——

The LARK SPK6 system is a professional sound reinforcement speaker specially tuned for classroom, the main speaker promotes the sub-speaker, no need to add additional amplifier equipment. Amplifier module with independent volume adjustment, 3pin Phoenix terminal mono balanced input, RCA stereo input; built-in DSP optimization to ensure voice clarity; amplifier module contains overload protection, short circuit protection and other functions.
