Detailed : Features ◆ A public broadcast controller that integrates playback, intelligent timing control, audio matrix, partition control, and other functions. ◆ There are 5 sets of timing schemes, each with 500 timing points, which are 7-day cycles. Each timing point can control the partition's sound source selection, chime, internal MP3, built-in AM/FM, 2-way power supply, and 4 external peripheral sound sources (CD, tuner, cassette, MP3 program player). The 5 sets of timing schemes can be easily switched. ◆ Eight-way ordinary sound source input, built-in MP3, AM/FM radio, one local aviation microphone input (with first priority function), one alarm signal input (with second priority function), one remote paging microphone signal input (with third-level priority function), one telephone paging signal input (with fourth-level priority function), and a large audio matrix with 40 outputs. ◆ 40-way fire emergency input (short-circuit signal), one fire linkage output (short-circuit signal, used for expansion, can be connected to MP99/8815E, MP99/8823S, etc.). (Each emergency input can trigger a programmable partition, and can trigger any partition) ◆ Through the LAN interface, an external computer can be connected to control the host through software. (Realize the computer to remotely set the timing, fixed point, and fixed program to automatically broadcast) (This function requires the purchase of remote control software to achieve). ◆ Can expand the remote paging microphone through the 9-pin port. ◆ All timing programs can be easily intervened manually at any time. ◆ Can monitor each partition in real time, with volume adjustment function. (Digital volume adjustment). ◆ Adopt high-performance DSP processor, digital matrix, digital volume control, digital equalizer, 7-inch color screen + touch panel. ◆ There is a USB interface, and the USB port can copy the songs in the U disk directly to the host for playback. ◆ 100-meter range wireless remote control, with 12 programmable buttons, can be customized to open/close the partition, select the sound source, select the song, etc. with one button. ◆ With 3 types of bell signal output function (digital volume adjustment). ◆ With alarm signal output function (digital volume adjustment). ◆ With telephone zone paging function (digital volume adjustment, password modification, full zone paging, self-selected paging, group paging, etc.). ◆ Can control the playback status of external sound source at a fixed time. ◆ With touch screen touch point calibration function. ◆ 40-way zone output digital volume adjustment function, can be remotely controlled.
