Hi,

I have a JVC HD750 that is ceiling mounted in my hallway, aiming through a hole in the wall to my lounge. The remote works ok at the moment by pointing it at the screen.

However, I am expecting the signal to be blocked when I fit my prismasonic lens. I was hoping that there would be a socket to plug an ir extender straight into the PJ but no such luck.

The plug in extenders I have seen are quite bulky, does anyone know of a neat and tidy solution to my problem.

Thanks,

Graham

about the smallest rf extender I have scene is the universal mrf260. you need to use this with a universal brand remote though.

Really you need an IR repeater. That gets hard wired, but then there is a very small emitter that sticks to the projector. Check out Xantech for instance...

Thanks for the replies.

I had a look at Xantechs site, :eek: so many choices. I will have a better look later to see if I can decide what to choose,

Sounds good. Are you using a universal remote? If not, there are some with RF/IR options that would also work.

An IR repeater requires a wire to be ran to the projector. I was assuming that since the projector was in a finished area that you would want to use a "wireless" solution. If you can get a wire to the projector then Jason is right and just use a simple connecting block. The negative to this method is that you also need to use an IR receiver in the room probably near the screen for ease of use. I personally like the wireless solutions better because they are MUCH easier to install and you don't have any devices in your theater that you have to look at.

Here is just an example of the many RF remotes with base stations.

Hi Chadly,

Wires won't be a problem. Between the PJ and my hole in the wall is a 'snoot' that I made. It looks good and cuts out stray light from coming through the hallway into the lounge. I found a small 'Marmitek' unit on amazon for £21.90 that looks like it would do the job.

I was considering mounting it on the underside of 'the hole in the wall' with the mains adaptor and ir sensor hidden inside the snoot box. The only visible part would be the receiver box.

Before the anamorphic lens got in the way of the PJ's sensor I used to aim the remote at the screen and bounce it back through the hole. If the Marmitek doesn't respond too well I could put the receiver just above the hole and aim it downwards. By holding the remote in front of my face it will point nicely at the receiver.

Thanks,

Graham

Hi Jason, I am using a Harmony One that I get on well with (Even the wife likes using it after about 6 months :D)


Thanks again,

Graham

I don't recall 100% but I do NOT believe that model has an RF option (only the higher end Harmony's do). This would limit you to replacing that remote or going with an IR repeater.
