Speaker control

Although the control method of the speaker has little impact on the sound quality, it is also a concern for both the manufacturer and the user because it relates to the comfort of the user interface.

The speaker control circuit generally has three major categories. One is a traditional control device fixed on the main speaker cabinet, and the other is a signal line control device. The last one is an independent remote control or remote control device.

The first control method is the most common, there are two kinds of knobs and buttons, but also the lowest cost, but due to the box, the operation is not very convenient, but also cause the problem of leakage of the box, so it is recommended The mid-range and above speakers selected do not use this mode of operation, especially multi-channel speakers, which will cause a lot of operational problems.

The second method is the signal line control device, which is to put the volume control and switch on the speaker signal input line, the cost will not increase a lot, but the manipulation is convenient, but this method has a new problem: the signal line due to the antenna effect , It is easy to be interfered by external interference sources, so this method is not the best choice.

The third and best control method is to use a dedicated digital control circuit to control the speaker's operation, and use an external independent remote control or remote control to control. For example, the innovative high-end speakers, Edifier paragraphs of high-end X.1 speakers, as well as Mai Lan, Lan Xin and other manufacturers of 5.1 speakers are using this design, this approach will not affect the sound quality. And more controllable features. In the case of ample funding, it should be given priority.
