专业音响系统中音量不足的情况检查顺序，一般情况下如果专业音响设备中出现音量不足的情况，就要及时检查功放和音箱的线路电平设置是否正确，其次还要了解音箱线连接是否牢固，还有就是功放与音箱的相位是否一致，均衡器衰减幅度是否在正常的范围，压限器的起控电平是否恰当。
In general, if there is insufficient volume in professional audio equipment, it is necessary to check in time whether the circuit level of amplifier and speaker is set correctly. Secondly, it is necessary to know whether the connection of speaker wire is firm, whether the phase of amplifier and speaker is consistent, whether the attenuation amplitude of equalizer is in the normal range, and whether the pressure is high. Whether the starting control level of the limiter is appropriate.
