Description:

It is widely applicated to classroom, multi-media classroom, office, conference room, prison, hospital office, metro, and other places, to broadcast background music, and to be used as local broadcast reinforcement.

Feature:

* Professional integration wall mounted design, sturdy structure, cabinet is conform to sound resonance principle design concept, with excellent appearance.

* Adopt embedded computer and DSP audio processing technology

* Built-in one channel network hardware audio decoding module, it supports TCP/IP and UDP protocol to realize the network transmission of 16-bit CD-quality audio signals.

* Built-in 2 x 20W digital amplifier, 1 channel to connect main speaker, the other connect assistant speaker to fulfill smooth and strong sound quality, with network volume setting.

* With 1 AUX input, independent volume potentiometer control, support offline local paging function. Support mute volume preset and background music preset function.

* Support connecting with Bluetooth receiver to receive Bluetooth audio for local sound reinforcement.

* Built-in 2.4G wireless audio module, transmission frequency: 2.40MHz-2.53MHz, high fidelity, good anti-interference, and realize 2.4G wireless microphone for local sound reinforcement. It is the industry's highest 64K @16bit×2, with HDCD sound quality effect and the best sound quality. Sound delay <0.5ms; response frequency: 80Hz-16KHz.

* Automatically enter the pairing state when it is turned on. After the pairing is successful, there will be a prompt sound and it will automatically switch to the receiving state.

* Automatic pairing connection distance between the controller and microphone is ≤ 3 meters, and the pairing connection time is ≤ 3 seconds.

* Realize encrypted transmission, the receiver supports automatic frequency sweep function to easily avoid interference.
