Caution
Danger
Preparation Before Installation
●During transportation, handling, and installation of switchboard equipment, avoid collisions
between the switchgear equipment and doors, walls, shelves, etc.
●When the equipment is unpacked and transported, it is strictly forbidden to put it down and
drag it gently to avoid damage to the switchboard equipment.
●Do not place the switcher equipment in a flammable, explosive atmosphere or smoke
environment. Do not perform any operation in this environment.
●Operating equipment should be kept away from water and moisture. The water in the
switchgear or moisture will cause damage to the circuit of the switchgear equipment.
●A certain amount of heat will be generated during the operation of the switcher. Ensure that
the switchgear equipment is ventilated and the switcher device can operate normally.
●It is a fatal hazard that indirect contact with the power supply by wet objects is prohibited.
Unregulated, incorrect high-voltage operation can cause accidents such as fire or electric shock.
●It is forbidden to install and remove the switchgear equipment and power cord. When the power
cord is in contact with the conductor, an arc or spark may be generated, which may result in fire
or electric shock.

SWITCHER
High-definition video switcher adopts a portable integrated design, metal casing, small size and
light weight. Standard size: 236mm * 105mm * 47mm, which can be used for small-scale
out-of-field video effects switching requirements. The device integrates multiview processor,
special effect generator, audio processor, control keyboard and other common components of the
switcher.
Switcher supports 4 HDMI + 1 DP signal inputs, a total of 5 video signals. The external
preview signal can be output simultaneously. The switcher supports HDMI embedded audio +
external analog audio. After mixed processing, it can be embedded in the output HDMI signal or
output from the analog port. The resolution of all input signals is automatically adapted, and the
output signal resolution can be selected according to requirements, which is quite flexible. For the
needs of video switching such as radio and television, program production, live production of
interviews and lectures, outdoor sports events, and school courseware production, the functions of
the switcher can be fully met.

introduce you the panel and interface of the HD switcher to facilitate your subsequent use and operation.
The new high-strength characteristics of the new aluminum alloy with high-strength characteristics
improve the anti-drop, anti-shock and shock-proof capabilities of the whole machine, and effectively
protect the internal components of the equipment. Ultra-lightweight features make the unit easier to
transport and maintain without the need for additional equipment; it also offers unparalleled thermal
performance.
In addition to the innovation of the case, the HD switcher has also been completely optimized for the
interface connector. Environmentally friendly materials with new RoHS standards are More demanding in
terms of durability and environmental protection, to provide customers with more stable, more
environmentally friendly, more cost-effective products
