amplify ir signal...

hello, i've been using a xantech 780-10 ir receiver for a year now in my living room. it has worked great, except that it does not have a lot of range reception. things are good as long as i keep good batteries in the remote, but it would be nice to pickup a few more feet of overall range.

does anyone know of any tweaks that i could make to the 780-10 to bump the reception range? is there a limiting resistor in the circuit that i could decrease the value of?

i'm on the verge of buying a 780-80 which boast >70' of range versus the 25' range of the 780-10. with this in mind, i'm not too worried about damaging the 780-10 with a tweak attempt.

aside from that, are there other in-wall ir recievers that would be better than a xantech 780-80?

btw - i don't have a plasma tv, so ir flooding isn't an issue.

just wondering if anyone had any ideas to improve ir reception without modding my remotes. currently i've got a range of ~18 feet pointing the remote straight into the xantech receiver which claims the range should be >22 feet. i am running a 3 wire setup on the receiver sending +/- voltage and returning a signal output.

the ir travels via cat5 wire (~50') to a xantech ir distribution system which does its own amplification and supports multiple ir transmitters and blasters.

my questions are...

1. could i build an amplifier the signal in between the receiver and the ouput line?

2. should i try a 2-wire setup for the 3 terminals (i've read about doing this on the buffalo devices).

3. should i just sell the xantech 780-10 (>22' range) and purchase a xantech 780-80 (>60' range) which is used to improve plasma/flourescent/daylight areas?

4. would a 780-80 give me much increased range even though my current eye is not greatly influenced by plasma/flourescent/daylight?

any ideas would be greatly appreciated. thanks!

what i meant by the two wire setup was that some people using buffalo equipment have claimed improvments by using two wires per terminal instead of one...

thanks for the link to the ir receivers. do you think that i could find the part number of the existing ir receiver on my unit? i'll try the xantech site to see if they publish any info on it...
