Hi,to know what watts to use for marantz pm74d, first you will need to know the watts of marantz pm74d for you to be able to know the watts of the speaker you will want to use for marantz pm74d.

You make sure the watts of the marantz pm74d you want to use for the speakers are not bigger the watt of the marantz pm74d,

eg, marantz pm74d----150 watts
speakers depending on the numbers of speakers your using 60 watts.

So if you are using one speaker of 60 watts and your using more than one, add all speaker watts and divide the speaker watts by the marantz pm74d watts, the weight on the marantz pm74d will be too much to handle too much speakers.

Make sure the marantz pm74d watts is high enough to carry the speaker you want to use.It helps you determine the quality of sound you want to hear..

Thanks for using fixya........

Take a look at Marantz's ZS5300 6 ch amplifier. that'll give you 3 stereo zones. Good luck!

All transformers buzz though you cannot hear it normally. The big transformers on power lines like to buzz for all to hear. When a transformer in a stereo amp gets old and deteriorates or gets hot and  expands the coils, melts the coil varnish and epoxy coatings then rattles at 60 times per second.    You can ignore it or change the transformer. There are too many layers of windings to try to stick anything in there.  Disconnecting a transformer results in inductive kickback -that's not money. It's a big, whopping electrical gotcha! Be careful! Good luck, Steve Medley

Sounds like an internal prob within the reciever, since recievers have radio tuners in em, maybe a prob in the input switching in it. I assume you are running unbalanced rca cables out of the dvd player into the reciever as it probably doesn't have balanced input capability, unbalanced lines are susceptible to R.F.I. ( radio frequency interference ) but I doubt if that's the problem here unless maybe you are running very long cable lengths from the dvd player to the reciever. Try using a different input and see if the problems still there, can use any input other than phonograph really as they are all line level inputs.

Knot a known falt may be only run 2 zones at a time

Hi...

Try another GOOD speaker on your centre channel.
If the buzz ....buzzes off, it's a bad speaker.
If not , It's in the power amp section on the unit.

There is a fairly simple fix to this problem here: http://www.audiotoolers.com/ubbt/ubbthreads.php/topics/5316/Problems_with_Marantz_PM4000_A.html
