We are a Sherwood Newcaslte Dealer who is seeing repeated problems and issues with ALMOST NEW m#/ R-772 surround sound rec'rs. Looking to see if any other dealers are seeing the same issues. Our rep says we are the only dealer complaining of so much trouble with Sherwood surround rec'rs.
Most of the problems we are seeing are with the m#/R-772 which goes into shutdown (protection) after 20 minutes of running with with both the surround sound turned on and zone 2 at the same time. If 1 or the other zone is turned on with out the other, the rec'r seams to play fine. We have had 3 units do this to the point that we had to remove them from the custom's homes. And we have had 4TH 772 do this twice but seems to work ok right now and was left at the cutomer's house.
1 of the 772s; zone2 (room2) is loaded up with 5 ultra match volume controls which have either 4 or 8 ohm loads on the controls, another has zone2 (room2) is loaded up with 2 ultra match volume controls which have 8 ohm loads on the controls and the 3rd did not have any speakers connected to zone2 (room2) because a seperate amp was feeding the load in zone2 (room2) via the R-772 zone2 (room2) line level out.
We also have 2 customer's with 1 year old #/R-771 whos systems worked fine on zone 2 until recently and are now going into shut down at low volumes.
IS ANYBODY ELSE OUT THERE SEEING TROUBLE WITH SHERWOOD NEWCASTLE SURROUND REC'RS?????????

No manufacturer has EVER had a common problem. You are always the only one with this problem. Don't know why this is, probably a law of nature cuz the reps never lie.

With that said, have you investigated the other possible source of trouble-the volume controls? I would suggest you hook zone 2 up to a single speaker pair w/o vc and try it. I have had an ongoing problem with the Jamo slider vc's shorting on 1 channel periodically.

I think your problem is....



...It's a Sherwood!

The only problem I have ever had like that was with a Denon, but I had the zone 2 volume almost all the way up. Turned down to about 2/3 everything is still working like a champ for years. I use Newcastle with no problems.

Actually that's not at all the case Stanley. Stepped in it nice and deep with that remark, you did.

You have any idea on how much stuff they OEM?



Sounds a lot more like installer error.....

I've used Sherwood "Newcastle" extensively with no more issues, and probably quite a bit less, as a rule, than many other brands.

Trunk-Slammers,
I'm sorry! I DO apologize! I was just flippin' ya a little crap. I sell Sherwood also, and it is a great value for the money! My apologies to you, Sherwood, and all Sherwood dealers here. It is, I repeat---a solid product and at a reasonable price!!!

Today, one of techs reported to me that 1 of the 772 was reinstalled this past saturday with a 6way Jamo speaker switch; with 1 switch feeding each volume control [total = 5]. The problem was worse even though we believed that the switch box would add additional load resistance and hopefully solve any shut downs caused by low impeadance. Even though the unit shut down more often, the switch box was left in the system over the weekendand the customer was told to advise us how often it shut down until we returned on Monday. Customer reported not only did his 772 shut down after 20 minutes of playing, it also came on by itself 3 times after shuting down and cooling of about 30 min later.
Our next step is to try an outboard amp for zone 2 to see ifthis makes a differance. I have also been considering purchasing an impeadance meter. Any of you guys use 1 on a regular basis and found it worth the investment?

There's something thing you can try that may take care of the problem.


Check the jumper settings on those Russound VC's, then turn ALL the remote room VC's to max level, then slowly ramp up the zone 2 volume level on the 772 until you reach a decent listening level.

Do not give the client the ability to adjust the 772 zone 2 output level....





That fails (it really shouldn't) you can do this by using line level, from the 772, connected to a seperate amp to power all those other speakers (yes, this WILL absolutely correct the problem).

Thanks for all your input. I am happy to report that the R772 that is connected to the 5 Vol. controls is working fine after my "right hand man" tracked out all the feed lines to the volume controls (running under the house in a dark crawl space) and found 2 staples that were going thru the 4 conductor and not around it! After removal of the staples the unit is reported as playing fine for 4 days straight.

Staple the guy's "tool": to the side of his van. Release the emergency brake.
