Installation and connection method of bar lighting and sound equipment

Installation method of bar lighting and sound equipment

1. Installation method of bar lighting and sound equipment. Firstly, the pipeline and hanger shall be embedded. This project needs to be started after it is confirmed. The embedded pipelines are mainly in the stage that has not been built or in the ground and wall without decoration. If they are not embedded in time, it is easy to affect the progress of the decoration project. At the same time, it must be paid attention that the outlet of the embedded pipeline must be handled in cooperation with the decoration Department. Otherwise, the beauty of the decoration may be affected due to improper handling.

2. The welding and installation of scaffold shall be carried out in a cross way with the decoration works as far as possible, because it is inevitable to open some holes and damage the existing decorations during the construction, which need the assistance of the decoration construction party.

3. Cable laying as the simplest process, cable laying should also be carried out carefully. Reasonable methods shall be mastered for laying cables. For example, when threading pipes, the steel wire and the cable to be threaded shall be tied firmly, the binding head shall reduce the resistance, and a small amount of lubricating oil shall be applied when necessary.

4. Installation procedure installation procedure of equipment - check the integrity of lighting and audio equipment when unpacking to see whether there is a lack of quantity. Install and debug the equipment one by one. The sound box should be placed in the small room and can be hung in the small room at the same time.

5. After the installation and commissioning of the equipment is completed, all equipment shall be inspected for the last time to see whether there is looseness or instability. Finally, carry out the final commissioning of all equipment, and call the customer for acceptance after confirming that there is no problem.

Key link points of bar lighting and sound equipment

1. Connection sequence of bass system equipment: mixer (1-2 marshalling) → equalizer → frequency divider → voltage limiter → bass power amplifier → bass speaker.

2. Connection sequence of auxiliary sound system equipment: mixer (3-4 marshalling) → equalizer → delay device (optional) → voltage limiter → auxiliary speaker power amplifier → auxiliary speaker.

3. Connection sequence of main audio equipment: mixer (L-R main channel) → equalizer → exciter (optional) → feedback suppressor (optional) → voltage limiter → main speaker power amplifier → main speaker.

4. Connection sequence of monitoring audio system equipment: mixer (AUX output) → equalizer → voltage limiter → monitoring speaker power amplifier → monitoring speaker.

Function of bar lighting and audio equipment link

The first connection mode can control the volume of bass separately, so that the volume of 1-2 groups of the mixer can be turned up when we shake slowly or Digo, and it can be turned down when the singer sings, which is very flexible;

The second connection method can also well control the sound of the auxiliary speaker;

For the ③ main speaker, of course, we are used to outputting the volume from the L-R total output of the mixer;

The ④ monitoring system outputs the volume from aux, which can flexibly adjust the volume of each channel of the mixer according to the requirements of the singer or band. However, in a smaller sound system, the monitoring signal can be taken directly from the main channel signal.

It should also be noted that since ① - ② and ③ - ④ groups have independently output signals from the corresponding output ports to the bass system and auxiliary system, ① - ② and ③ - ④ groups should not be output through the total volume of the mixer, that is, the switching switch from ① - ② and ③ - ④ groups to the total volume of the mixer should not be turned on.

Of course, we should flexibly arrange the order of equipment connection according to the needs and the number of equipment. The above order is only for reference.


Key points of audio equipment connection

The above briefly introduces the types, production and equipment connection sequence of various connecting wires. In the specific connection of equipment, in the face of various and a large number of equipment sockets, many sound engineers don't know how to start. In fact, it's very simple. Just remember the following points:

1. Balance mode: at present, the sockets on the rear panel of most audio equipment are balance ports. We just choose whether to connect the equipment with the balance line of XLR XLR connector or the balance line of TRS 6.35cm stereo connector.
