The wiring system and piping construction method of the broadcasting system are the same as that of the electric power engineering wiring.
2, broadcast system equipment installation(1) Pay attention to the shielding of the piping and wiring of the broadcasting system, and use the shielded cable in the middle to prohibit the joint.
(2) When connecting the equipment and connectors with shielded cables, pay attention to the connection of the shielding layer. When connecting, use welding. Do not use twisting and winding. Welding is firm, beautiful and reliable.
(3) When wiring the system, each terminal should be numbered, and the number can be written on the plastic conduit with a number pen. At the end of each output line, a sign shall be attached to indicate the direction of the wire and the line number.
Surface mounted wall-mounted speakers are pre-configured with expansion bolts or buried pendants according to the height and angular position required by the design.
(4) Set the embedded speaker in the ceiling, connect the lead terminal with the wire inside the box, hold the speaker with the speaker to make it close to the ceiling, and fix the speaker to the ceiling bracket with screws. When using a spring to fix the horn, attach the horn to the ceiling and connect the spring, hook the horn cover and use it to fit on the ceiling and position it.
(5) When the large cabinet adopts the channel steel foundation, first check whether the channel foundation is straight and its size meets the cabinet size.
(6) When a combination audio system such as amplifying, recording, or laser recording is provided, the equipment should be installed into the cabinet one by one according to the technical requirements of the manufacturer of the equipment, and the bolts should be fixed and leveled.
(7) Connect the equipment with special wires, the wire ends of each branch are crimped, and the equipment and shielding wires should be crimped to the protective ground wire.
(8) After the equipment is installed, the power supply should be placed in the disconnection position before commissioning. After each equipment is tested and tested, the whole system will be adjusted. After the commissioning, the relevant personnel will be accepted and delivered.
3. Broadcast system control system debugging(1) System commissioning should be carried out after the system equipment is installed and the power is on.
(2) Sound quality audition should be performed for each broadcast speaker, and debugging should be performed based on the results of the audition.
