The equipment should not be overloaded, the shouting loudspeaker should
not exceed the power of the power amplifier, and the total power of the
other three loudspeakers should not exceed the power of the power
amplifier, so as not to damage the equipment or reduce the service life
of the equipment due to overload.
2. When the equipment is working normally, if the volume decreases too much when connecting any loudspeaker group, it means that the load is too heavy or there is a short circuit on the outside line. It should be checked immediately and turned on again after troubleshooting. If the fuse is burnt down, the cause should be clearly explained. After troubleshooting, the fuse with the same capacity should be replaced. Copper wire should not be used to replace the fuse, so as to avoid burning down the equipment.
3. The number of cable cores between remote control station and loudspeaker is not less than 1 mm2. The shielding net and shell should be connected reliably. The three lines of loudspeaker with volume adjustment should be connected in sequence.
4. The installation position of public broadcasting remote control station should avoid loudspeakers, so as to avoid screaming, especially when the loudspeakers with higher power can not be directed at the remote control station, and when the remote control is also operated by telephone, the telephone should avoid the installation of loudspeakers.
5. The AC voltage used in the system should be maintained within 198V~242V, and the DC voltage should be maintained within 192V~28V, and attention should be paid to the positive and negative polarity.
