Thanks for the input guys I have the same situation right now with a 61 in Runco. My question is will audioplex stuff work with xantech?

Just to add to KDP's question (same job) the room is
large and has a game room to one side, there is another system in the game room and the light from the 61" Runco is affecting that room also, the VCR and DVD control seemed to work "ok" but the Denon Rec wont work at all, If I move the eye aroundthe corner it works fine, but is not in a convient location. I used
a dinky link,table top and micro link, all Xantech,
tried all the tape, paper, backward,speakergrill,and even moved it i front of the couch 20 feet away,under tge coffee table, still no luck. I guess I'll try the audioplex stuff.
By the way the picture on the Runco is unbelievable!
thanks

I've worked with the Audioplex sensor and it works very well hooked up to Xantech or Audioplex IR connecting blocks.

In most systems it is not necessary to use anything but the standard frequency model. Most (95%) remote controls in the North American market issue a 40khz carrier wave, the largest exception is RCA, who most frequently use a 56khz carrier. If your system includes european gear however, all bets are off. Many european component manufacturers utilize carrier frequencies that are far too high to be compatible with Xantech or Audioplex sensors of any type. Oyvind, you should check with the manufacturers you are using in this job. See if the remote control carrier frequency is between 32khz and 44khz.

An explanatory note on the Plasma problem: The reason we have so much conflicting advice here is that the interference is both EMI and Optical.

Metal shielding (and a good ground, guys!) can reduce EMI to nothing. Optical interference only occurs when the Plasma is ON, so simply telling your customer to avoid using a picture in their home theater... Whoops, I guess that wasn't as funny as I thougt. Anyway, optical interference can be beaten two ways. Simply make the opening of the sensor more opaque or smaller, that will reduce the amount of interference but will also lower the range. The other way is the way the Audioplex and the Xantech CFL sensor works. They have found that the plasmas output a ton of interference centered around 40khz. So the pulse pattern gets through the repeater system to the component and can be counted, but the component will not recognize the pulse pattern since the carrier frequency is jammed. Audioplex and Xantech strip the carrier, thus removing all of the interfering noise from the plasma, then generate an artificial carrier that looks fine to the av components.

The methods vary a little in terms of installation. The Xantech will only work at one frequency, but you can adjust the frequency on the sensor itself (thus on a job with both Sony 40khz and RCA56khz, you might be able to find an inbetween spot that works), Audioplex make fixed frequency versions so a mixed system you have to use two sensors.

I've used both Xantech and Niles Dinkylink sytles and Micro Link (tube) stiles, and found the microlink worked best next to the plasma screen. We did mount a dinkylink directly to the side of a Panasonic plasma once and even though it had a steady glo to the status light it seemed to work normal...We'll just have to wait and see...It sucks when the customer insists that you set something up that way. Save a buck on parts and pay a lot more on service calls in the long run...

The hiden link kit would be nice if it did work(out of site ,out of mind)but the wall the plasma is hung on is rock.we are waiting for the audioplex piece now will post back on the results

A little help here please? I've just received my account number and have questions for the Forum, but I can't figure out how to post a question. You'd never know I've been in the Electronics business for 32 years. I ffel like a real jerk.

Thanks,
George

George, at the top of the screen on the message board there is a link entitled "add a new thread" click on it and off you go
