Powering nine home speakers
Can I ask what’s the risk if the impedance doesn’t match (ie using the current speaker selector and a second amp)? Harm to the equipment or just uneven sound?Not too many power amp can handle 2 ohms or less load, Some amp protection circuitry will lower the output or shut itself down, some will over heated and caused damage! That’s the reason for impedance protection circuitry. If you want to use the ATM7, wire the speakers close to 8 ohms: http://www.colomar.com/Shavano/4ps-spkr.gif |
Try connect 4 speakers as a group follow the wiring diagram, one group for right channel and one for left channel, leave the last speaker unconnected and see what’s the result. http://www.colomar.com/Shavano/4ps-spkr.gif https://www.amplifiedparts.com/tech-corner/speaker-impedance-power-handling-and-wiring Please refer to ’Example 4’ |
jj91709, Unfortunately, you seem to have no desire or interest in a good quality music reproduction system for your room and, as a result, I find I've lost interest in your system, myself. Just hire a company that installs background music systems in restaurants and businesses and be be done with it. You'll be listening to Yanni 24/7 via glorious mono in no time. Later, Tim |
