Product Overview
Wall-mounted IP network audio encoding and decoding terminal, built-in stereo constant resistance power amplifier, suitable for configuration in hotel rooms, classrooms, etc.
Features
- Standard wall-mounted design, aluminum alloy integrated structure, exquisite and beautiful, exquisite technology.
- The equipment adopts industrial dual-core processing chip (ARM + DSP), and the startup time is less than 1 S.
- Built-in network IP decoding module can play network music and call function in real time. The network delay time of the acquisition play and call functions is less than 30 mS.
- Built-in 2 × 20 W digital power amplifier, less heat, higher efficiency, CD level perfect sound quality.
- One microphone input, one line input, one line output, suitable for on-site local public address broadcast function.
- Priority function: network alarm is the highest priority. The local MIC and AUX are of the same level, their level is adjustable.
- Microphone reverberation adjustment potentiometer is installed inside, which can make the voice more full and elastic.
- Built-in 2.4G wireless microphone receiving interface, microphone volume can be adjusted independently.
- With a short circuit input and a short circuit output interface, it is convenient for users to expand.
- The terminal will automatically enters the sleep state when there isn't any signal input, and the power amplifier output has no noise.
- The terminal panel is equipped with power indicator, network connection indicator and audio signal output detection indicator, so that the working status of the terminal is clear at a glance.
- One 10/100MRJ45 network switch interface is standard, supporting LAN and Wan.
