In the audio sound dilatation system design, device matching is also a very important link.

If there is a problem with a certain or several equipment, or if there is a problem with the grade, quality, selection, and matching, it will form a "bottleneck" or "conflict".

Because most of the equipment of the audio system work in series, the output of individual devices (such as tuning tables, system processors, etc.) controls the entire system or transmits signals of the entire system (such as network system equipment, etc.).

Even if many top -level single audio equipment is selected, there is no accurate, reliable, reasonable, and practical control, just like combining several world's precious musical instruments and performance masters, not to give the Canadian command; If the equipment selection is different, the high and low, the low -level and inferior equipment drag the hind legs, some of the high -level equipment cannot restore the beautiful sound.

Therefore, from the perspective of selecting the device, first consider the applicability of the system and the consistency of the equipment, to meet the needs of various functional and system signal processing, and reserve the space for upgrades.
