● Employ 4×4.5-inch full-range speaker units, providing uniform 360-degree sound coverage for enhanced performance.
● Indoor sound field uniformity: The difference between the maximum and minimum steady-state sound pressure levels measured at various student seating points within the indoor environment should be within a range of 4dB.
● Speech transmission index for public address systems ((STIPA): ≤0.7.
● Rated output power of the built-in amplifier: 4×15W.
● Support Bluetooth function: It is equipped with a built-in Bluetooth module of version 5.1, enabling wireless audio reception and convenient sharing of audio from mobile devices. It also allows for the modification of the Bluetooth username and password to prevent unauthorized connections.
● Wireless microphone teaching function: It includes a built-in 2.4G wireless microphone signal receiver module, enabling the use of a paired wireless microphone for local sound amplification. It supports one-teacher-one-microphone usage, PPT page-turning, and laser pointer functions.
● WeChat mini program function: The speaker supports connection via the WeChat mini program, allowing independent volume adjustment for the sound units in all four directions (front, back, left, and right). It also enables individual volume control for different audio sources, including AUX IN line input, wireless microphone (MIC), Bluetooth, and network audio sources, as well as the ability to modify the audio source priority. Additionally, it provides the option to turn on/off or modify the speaker’s color light effects.
● Audio source priority function: It supports flexible adjustment between three modes: network audio source priority, local audio source (Bluetooth, wireless microphone) priority, or a mixed mode combining both network and local sources.
● Support standard SIP protocol, allowing integration with SIP phone systems to enable paging and voice broadcasting via SIP phones or mobile phones.
● With 1 mono local line input and 1 stereo local line input for connecting a local integrated system or other audio source devices to expand program sources.
● With 1 stereo local line output for expanding local power output.
● Support remote web access to the speaker’s web interface, with options to set password protection for the web interface and switch between Chinese and English. Once logged in, users can modify the speaker’s IP address, SIP parameters, priority settings, and speaker channel parameters.
● Feature a built-in full-color working status indicator light strip, making the speaker’s working status clearly visible from a distance. The device can display different lighting effects to indicate network playback, idle status, or offline status, and it offers ≥10 effects such as breathing light, flowing light, and gradient color light, with adjustable speed (high, medium, low).
● Include a built-in clock display screen to show the system time and device status. With a remote control, users can adjust the volume for local line input and network audio sources, as well as view or modify network parameters such as the device’s IP address.
