How to connect the active speaker line array?

Update time : 2019-10-28 09:54:21

There are many types of audio system connections, and different systems and devices have different connection methods. Generally, the sound system is flexibly matched according to the use characteristics and customer requirements, but the effects of different connection methods of the same device are also different. Choose different speaker types and they will be connected differently. The most simple and practical audio system connection for active speaker connections.

Active speakers typically use power integrated circuits, built-in amplifiers, low price, simple design and has a complete protection. The connection is simple and easy to use, and the active speakers greatly simplify the connection of the sound system, using less audio cables and reducing the cost.

Taking the COX-5.4 line array as an example, the COX-5.4 is a mini 2-way active line array. Active speakers greatly simplify the interface of the sound system and are very simple to connect.

Connection method: audio source equipment--mixer--audio, chain connection between devices.

First, turn on the main power supply to ensure that other matching equipment is in power supply.
Second, refer to the figure below for connection.
1) Power input: The speaker power is turned on.
2) Power connection: The power between the individual speakers is turned on.
3) 4) Mixer signal output and speaker signal input: The connection between the mixer and the speaker connects the signal line of the mixer to the signal input of the speaker.
5) Turn on the speaker power switch.
A simple connection is fine, and you can debug it based on the sound you play.

Active speakers are often referred to as speakers with power amplifiers. With built-in amplifier circuits, these amplifiers are designed to drive horns inside the speakers. Thanks to the special matching design, these amplifiers can be used to push them well. Therefore, the user does not need to consider whether the power of the amplifier and the impedance match. It is also easy to drive directly with lower level audio signals.

Issues to be aware of when connecting devices:

1. Pay attention to the power supply: The audio equipment must have a dedicated power supply. It is crucial to connect the power supply of all audio equipment correctly and securely.

2. pay attention to choose the appropriate connection signal line: a sound device, try to use XLR card balance line to connect. When connecting devices, try to use shorter signal lines to save costs and reduce line resistance and interference. Under normal circumstances, the signal line using balanced transmission can be up to 300 meters, while the non-balanced line can not be transmitted over long distances.

3. pay attention to the signal inversion and short circuit: signal line short circuit often causes silent fault, it is very troublesome to check, unless a strip of signal line is removed and tested with a multimeter, so be careful when welding the line.
