DSP225NM Teaching Speaker

Features

● Based on the TCP/IP protocol, the network multifunctional decoding player can work across network segments.
● Support standard SIP protocol.
● Adopt RFID automatic frequency pairing technology, to realize automatic frequency pairing with the receiver at a certain distance without manual operation.
● Adopt 2.4G frequency pairing method to obtain a larger range and stronger anti-interference ability. After the receiver is paired with the transmitter, the pairing signal of the receiver will enter a silent state to avoid crosstalk of other devices nearby.
● Adopt anti-crosstalk voice encryption technology. When the device completes the frequency pairing to enter the voice transmission, the voice transmission between the devices will be under digital encrypted transmission, and other devices cannot communicate with the receiver.
● With three levels of adjustable voice receiving distance, to set three kinds of voice receiving distances, the largest for a space of about 15×8 meters, the middle for about 12×6 meters, and the smallest for about 9×6 meters.
● Multiple audio input: wireless MIC IN, MIC IN, 100V IN, AUX IN, network audio input.
● Support multiple audio formats: MP3, WAV, etc.
● Support one-key remote paging.
● With various control interfaces, such as I/O port and RS485 communication port.
● Can play the BGM, emergency paging and alarm signals from the host system.
● Can be controlled and played through the management software.
● Priority function: 100V IN/Network alarm>Wireless MIC/Local MIC>Network audio>AUX IN.
● Rated power 2×20W.
