T1812 IP network audio terminal

Product description
Detailed parameters
● In addition to the T1811 function, the T1812 also has an offline function, SD card local playback function, VFD display; optional program on-demand player to enable arbitrary listening to multiple sets of audio programs transmitted by the server.
● With dual port hub (HUB), it can directly access local area network (LAN) or wide area network (WAN), can play network audio, and can access and control servers and other IP network devices.
● Network fault self-diagnosis, network and server communication status display.
● Powerful network audio playback function, which can be used independently in the network, can directly play network audio signals from IP network audio matrix, IP network radio head or IP network CD.
● T1812 can control the control of the main control room server, control the sub-control point computer, and it can also directly control the internal communication intercom equipment such as network fire matrix, network paging microphone, etc., for paging intercom or fire protection. Emergency tasks are more responsive and more reliable.
● Audio channel selection listening function, users can choose any listening in multiple sets of audio channel programs transmitted at the same time. Audio channel programs can come from the server, or can be from audio matrix or IP network radio head and IP network CD.
●Optional program-on-demand device can realize arbitrary on-demand broadcasting of thousands of programs in the program library in the server. Users can use the first spelling letters to perform song query, which is extremely simple and convenient.
● The terminal is equipped with a MICRO SD card storage interface and comes standard with a 2G memory card.
● SD card local playback, support multiple song formats, high-fidelity sound quality decoding.
● Timed songs can be directly copied to the storage, or downloaded remotely through the server. All terminals in the same LAN can download at the same time.
● The timer program can be downloaded in batches through the server remotely. All terminals in the same LAN can download at the same time.
● Local timing can set priority. When set to priority, local timing will be executed first. When the local timing is not set to priority, the server timing is executed first. If a network failure is detected or the service is offline or a failure occurs, the local timing is automatically started to ensure that the timing task is foolproof.
● VFD display, with high-precision electronic clock, time display function, and the clock can be automatically synchronized with the server to ensure accurate execution of timing tasks.
● One line input, one line output, one microphone input, the microphone has a strong cut function.
● Line and microphone volume control, total volume control and high and low sound control.
● Built-in 2*15W stereo digital power amplifier, low temperature rise, safe and reliable, suitable for long hours of work.
● Automatically switch to standby mode when there is no signal, saving energy and environmental protection.
● Full-featured remote control (remote control and remote control components are optional).
