DSP225NM Teaching Speaker

Features

● Based on the TCP/IP protocol, the network multifunctional decoding player can work across network segments.
● Support SIP2.0 (RFC3261) and related RFC.
● Support narrowband coding: G.711a/u; broadband coding: G.722.
● Adopt RFID automatic frequency pairing technology, to realize automatic frequency pairing with the receiver at a certain distance without manual operation.
● 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.
● Can run independently from the network and the host.
