L8000 Contorl Block

Application:

Description:

▲Using digital technology as the core, built-in high-performance CPU, support discussion, video HDMI. ▲The audio signal is processed by 32bit high-speed floating-point DSP, with a bandwidth of 20Hz~20KHz, perfect and clear sound quality ▲High-performance switching power supply, long-distance transmission will not have any impact on sound quality ▲Anti-interference circuit design to prevent all mobile phone signal interference ▲Comes with 2.8-inch LCD screen, independent key operation ▲Two-way microphone connection, each way supports 50 units, can be connected to 100 units, supports 10 chairman units, and can be expanded to 512 conference units with an expander. The host output port has a traditional 8-core hand-in-hand interface and 4 RJ45 The network cable interface is used together. ▲With central control code RS-232 interface, can be connected to central control system ▲Multi-channel audio input and output interface, can be connected to sound reinforcement or recording equipment ▲The host computer and the computer can be connected and communicated locally by USB, and the system can be set up with PC software. You can also set the system directly on the host without a computer, and support online code update ▲Multiple conference modes: FIFO (first in first out mode), FREE (full open mode), C-ONLY (chairman mode)
