Title: Public Address amplifier System
Post by: Sosonne Gontier on February 11, 2013, 06:52:22 am
Could somebody help ? If I have 2 set of 9 speakers (8 ohms 50 watts each) to be connected in parallel and series with Resultant impedance of 8 ohms each channel, what will be the power output of the amplifier with 2 chaennel when the volume gain will NEVER be set to half of it's capacity.?

As it says above, your displayed name must be your real full name so you first need to fix that.

But to answer your question, it depends.  How loud are you trying to get?  What is the speaker sensitivity?  What type of content?

And why have you determined in advance that the amplifier level controls will be at 50% or less?  Do you understand that the amplifier input level controls are typically just adjust the input signal level for the amplifier rather than the amplifier gain and also do not limit the amplifier's potential output, only change the input level required to get that output.
