Amp Impedance with a Speaker Switch Box (1 Viewer)

[Newch]

Hi,

I have a Yamaha amp Model RX-V365 that has 6 Ohm minimum per speaker.

I have a Speaker Switch box from Dick Smith Model CN2547 that has a "Protecting circuit switch". It has 4 Zones. (4 sets of speakers). In the manual for the switch box is states "The protection switch can be turned ON to prevent the impedance to your amplifier from dropping below 5 Ohms, regardless of the number and impedance ratings of your speakers."

The speakers I am looking at are 4 Ohms. So my understanding is that if I connect 4 sets of these to this switch box it would drop the impedance quite low but if I then turn on the "Protecting circuit switch" it would keep it at 5 Ohms but that would still be below the minimum of 6 Ohm of the amp.

If I run it like that at say 3/4 volume would it still run OK?

If not is there some other way I can add an extra 1 ohm to this setup?

Do I need to look at different Ohm Speakers?

I would think I would have probably only 2 zones on at a time in reality.

Thanks in advance.

Your best - and safest - bet would be to use 8-ohm speakers.
