IP network speakers are suitable for playing recorded voice files or background music programs in ordinary classrooms, multimedia classrooms, offices, conference rooms, prisons, hospital departments, subways and other places, and also support local broadcast amplification.
* The speaker cabinet is designed with high-density wooden material, which has the advantages of shockproof, durability, exquisite appearance, etc.
* It has 1 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.
* The main speaker has a built-in 2× 20W (MAX) dual-channel Class D digital power amplifier, which is connected to the sub-speaker and adopts a high and low frequency division design; the sound quality is delicate and the power is strong; it has a network volume setting.
* Built-in network audio decoding module, supports mainstream audio formats such as MP3, WAV, FLAC, OGG, AAC, OPUS, etc., and is compatible with 8 kHz - 48 kHz full sampling rate.
* 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 equipment maintenance via the network to reduce staff workload.
* 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.
