Audio Public Address Sound System.

Zoomup
Mornin' All,

                    I need some advice please.


Imagine a portable sound system as used by travelling musicians, rock guitarists or others with electric instruments. There will be a large mixing desk, and amplifier and speakers. All is well if the musicians with electric instruments only plug their 1/4 inch jack plugs into their instruments when the mixer sliders are down (off) so as not to cause a big pop or bang through the speakers. Sometimes though the jack plugs are unplugged from the instruments when the mixer sliders are up (on) and a terrible sound results from the speakers.


Is there a "magic box" that can be inserted in line with the audio leads from the instruments to the mixer that AUTOMATICALLY prevents this unwanted loud noise problem?


Thanks,


Z.

    I suspect that the answer is "no" and I doubt that you would have much success in training good working practice.


    An everyday example ...


    A 3 kW electric heater is plugged into a socket which you want to use. Do you:


    (a) switch off the heater, switch off the socket, and remove the plug?

    (b) switch off the heater and remove the plug?

    (c) just pull out the plug?
