2. Audio: input: 5 groups of XLR balanced audio input, support LINE and MIC mode, and each with 48V phantom power switch, 5 groups of RCA(R, L) stereo input, 5 groups of SDI, HDMI digital audio add unembedded input;  Output: 2 groups of XLR balanced audio output, 1 group of RCA(R, L) stereo output, 3.5mm audio monitor output;  

4. Monitoring system: 6 independent 1920×1080 hd screens, 2 9-inch screens and 4 4-inch screens, one of which is a 9-inch screen display PGM live window, the other is a 9-inch screen display PVW preview window, 4 4-inch screens respectively display input signals;  Provide display selection button, with 10 screen segmentation display output, display 8 input signals and 2 output signals respectively;  

5. Internal call system: The eight-channel hardware guide call system and eight-channel guide prompt system TALLY provide eight groups of call selection buttons for individual calls, all calls, and mute calls in each channel.  

6. Audio processing:  Built-in digital mixer, analog mixer and audio delay, audio embedded and unembedded, realize the mixing of digital audio and analog audio, 5 groups of SDI, HDMI digital plus unembedded audio, 5 groups of XLR professional microphone or balanced audio, with 5 groups of 48V illusion power supply and 5 groups of RCA (R, L) stereo audio hardware mixing mixer,  The mixer has voice playback and audio processing, 7 groups of volume adjustment fuser to control the volume of digital audio, analog audio and main output audio respectively, 2 groups of XLR balanced output, 1 group of RCA (R, L) stereo output, 2 groups of HDMI digital audio embedded output and 2 groups of SDI digital audio embedded output, built-in audio hardware delay system,  Adjust the speed of audio by the hardware knob to achieve accurate synchronization of sound and painting; 

7. Camera PTZ control system:  Built-in THREE-DIMENSIONAL rocker, respectively control the push, pull, roll, pitch, and zoom of each camera, provide 9 groups of shortcut key prefabricated buttons and 2 groups of prefabricated setting buttons, each machine can realize 100 prefabricated positions, provide hardware rotary encoder to control the selection of camera address, provide camera manual and automatic precision control system,  You can set the camera white balance, focus, aperture, color, brightness, etc., to meet indoor and outdoor shooting needs;  

8. Recording system: built-in 4:2:0 coding recording system, to achieve constant frame and constant code recording, hardware recording system provides microSD /TF Card, USB and other storage interfaces, support TF Card, U disk and mobile hard disk recording, recording file format is MP4, can be directly imported into the nonlinear editing system;  

9, built-in Wifi: WLAN main specifications, PHY: support 2.4 band and 5G band 2X2;  MAC: Supports IEEE 802.11d /e/h/ I /k/w;  Supports the coexistence of 20M, 40M, and 80M.  Support IEEE 802.11b /g/n/ AC;  Transmission power: 11B@16dbm;  11 g @ DBM;  11 n @ 13 DBM;  MCS9 @ 13 DBM;  2.4g Receiving sensitivity (40MHz) : -80dbm @rate MCS 0;  -68dbm @rate MCS 5;  -64dbm @mcs7, 5G reception sensitivity (40MHz) : -80dbm @rate MCS 0;  -68dbm @rate MCS 5;  - 64 DBM @ MCS7;  

10, built-in audio and video coding system: video coding H.264, audio coding AAC, coding delay ≤67ms, video coding rate 256Kbps ~ 25Mbps adjustable, audio coding rate 32Kbps ~ 512Kbps, AAC coding 64Kbps;  

11. Live broadcast and release transmission protocol: support FMS live broadcast and release, provide RTMP push and RTMP service, and provide APP live broadcast setting system, which can remotely set the release address, push bit rate and resolution, etc.  

12, transmission and control: support standard 3G/HD-SDI input, interface BNC type, BNC interface with power supply and power supply protection, and control integrated connection, to achieve a 75-ω coaxial cable control and transmission of five signals, they are Camera full HD 3G/HD-SDI video signal + camera and XLR audio signal + camera power supply + camera PTZ control + guide warning signal TALLY. All signals, control, communication, and power transmission between camera and guide host can be completed in just one cable, which is the maximum solution to the wiring problem of mobile shooting.
