When designing and installing a set of conference audio equipment, it is inevitable to encounter the matching problem of conference audio and power amplifier. In terms of timbre, we will pay attention to whether the matching is suitable and moderate. From the technical point of view, the elements of conference power amplifier and audio are: power matching, impedance matching, and damping coefficient matching. If we recognize the above points when matching, the performance of all equipment can be fully and greatly displayed.
1. Power matching
The power between the conference speaker and the power amplifier must be matched. The comprehensive sound quality of the reproduced sound depends not only on the characteristics of the sound, but also on the output and load characteristics of the power amplifier. If the sound is not ideal, don't just think that there is a problem with the sound, but first consider whether there is a problem with the power amplifier connected to it.
Second, impedance matching
It refers to the rated output impedance of the power amplifier, which should be consistent with the rated impedance of the conference speaker. At this time, the power amplifier is in a better designed load line state, so larger undistorted power can be given. If the rated impedance of the audio is greater than the rated output impedance of the power amplifier, the actual output power of the power amplifier will be less than the rated output power. If the rated impedance of the speaker is less than the rated output impedance of the power amplifier, the conference audio system can work, but the power amplifier is in danger of overload, and the power amplifier is required to have complete over-current protection measures to solve it.
Third, the matching of damping factors
The basic conditions to ensure good sound playback's steady-state characteristics and transient characteristics. Pay attention to the coordination of the equivalent mechanical quality factor (Qm) of the sound and the damping coefficient (KD) of the power amplifier. This kind of cooperation requires the sound feeder to be used as the overall sound system Part of it to consider. The equivalent resistance of the feeder of the conference speaker should be small enough to be negligible compared with the rated impedance of the speaker. In fact, the power loss of the conference audio feeder should be less than 0.5dB (about 12%) to achieve this coordination.
