Description：

IP network speakers are suitable for places such as regular classrooms, multimedia classrooms, offices, meeting rooms, prisons, hospital departments, and subways. They are used to play reminder announcements or background music programs. Additionally, they can also be used for local broadcasting and amplification.

Features：

* The speaker adopts a professional integrated wall-mounted speaker design. The structure of the whole machine is very solid and the cabinet conforms to the design concept of sound resonance principle.

* It has 1-channel line (AUX) input interface, supports network volume adjustment, supports local sound amplification function when disconnected from the network, and supports background accompaniment preset function.

* The wireless audio module can be expanded to realize local sound amplification with wireless microphone. The Bluetooth receiver can be expanded to receive Bluetooth audio for local sound amplification.

* It has 1-channel short-circuit input interface. It supports software customization to realize alarm triggering media library music playback or volume adjustment function.

* The main speaker has a built-in 2×20W (MAX) dual-channel Class D digital power amplifier, and one channel is connected to the sub-speaker. The sound quality is delicate and the power is strong; it has network volume settings.

* Built-in network audio decoding module, supports mainstream audio formats such as MP3, WAV, FLAC, OGG, AAC, OPUS, etc., and is compatible with the full sampling rate of 8kHz-48kHz.

* Built-in DSP audio processing, supports ultra-low latency digital mixing, and 10-band EQ equalization configuration.

* Built-in 2-level priority settings: (1) Network alarm signals take priority over AUX and network background music signals. (2) Network background music signals and local audio input can be prioritized by the user as needed.

* Supports remote firmware upgrades and performs maintenance on terminal devices through the network, effectively reducing the workload of maintenance personnel.

* The system uses a data redundancy encoding and decoding algorithm and supports anti-packet loss recovery function. When the network packet loss rate is 37.5%, the audio playback is smooth.

* The end-to-end delay of the system playing collected audio is less than 5ms.
