Question about Mackie SRM-450 System

1 Answer

My speaker made a very loud noise and stopped working. It might have been a reaction to mics under my acoustic to which it was pointed. The mics belong to a PR1 acoustic piano recorder which was in use at the time.

Hi, you probably have a situation whereby speaker amplifier chip may leaky or damage. You need to change it.

Take care

High frequency noise form my 7.1 surround sound system


Is the microphone live? If so, what you're getting is called "acoustic feedback". Any room sound gets in the mic, gets amplified, comes out the speakers, and then gets picked up by the mic again. Louder and louder until you get to the maximum your system can do.

The solution is to turn it down. . . until it stops.

My acoustic research hd510 has a loud humming noise


check your audio line in connection, either L or R signal line floating may also cause humming noise. Sub woofer usually very sensitive. If your audio input not connected, do you still hear humming noise? in actual you should not hear such noise, unless volume at max then it is possible to hear little.
