integra 80.1

thanks blindjim,

i was always using separates, the onkyo receiver was only used as a pre amp tho. this allowed me to select 4 ohms in tbe onkyo and run my jbl amp @190 wpc in 4 ohm.

now, with the exception of the new processor, all the components/speakers are the same. the only difference is that the amp must now run @ 125 wpc in 8 ohms ( no ohm switch in 80.1.)

my concern is the unmatched ohm rating my 4 ohm rated m&k s125 speakers which are now being fed power from the 8 ohm rating.
i think the 8 ohm 125 wpc will be enough but i just wanted to double check if the mismatched ohm ratings are a problem.

sorry if i seem a bit confused, im not an experienced audiophile.

thanks so much for your help

The only JBL multi-channel amps I could find are the S5125,and the S7125.Both of those state do not use less than 8 ohm speakers on the back of the unit.8 ohms is the home theater standard like mentioned above.Its odd that M&K who seamed to focus on home theater to stray away to 4 ohms.I had their first(I think)sub woofer from the 80s.Running those speakers on one of these JBL amps can be risky for the amp.If your amp is a different model,double check the back of the amp,and owners manual.On my earlier post,I said the processor normally doesn't have an impedance switch.The reason for that is,I was told in the 90s there was a couple of them that had the switch in the processor.They weren't the normal.They only worked with their own equipment,and had a special 25 pin plus cord that connected to their own brand of gear.I can't remember the brand,but it wasn't Onkyo,or JBL.Like mentioned above,if your using Rca or balanced connection,the impedance can *not* be switched by processor.Some Onkyo amps have the ohm selector on the back of them.The majority of the amps say what they can run on the back of the amp.4 ohms is twice the load of a 8 ohm load.Harman Kardon may have a suggestion for you.Some of their processors are Lexicon,but I don't know who made the amps.If I don't post,its because my internet is having intermittent problems.Link for those amps I mentioned.[http://www.jblsynthesis.com/Uploads/Files/Site/JBL/S7165-S5165-S820%20OM%20hires.pdf]
