does anyone have any advice on building a headphone amp? seems to me there would be a better way than using splitters or spending $150 on an amp to get multiple headphone outputs. any adice would be greatly appreciated.
 
Maybe check PAIA. They might have a kit. Craig Anderton was associated with them on some level. Seems like I just saw something like that recently. Maybe an old PAIA catalog or an old magazine I have around here. If I come up with it I'll let you know.
 
Go to garage sales and pick up any old tape deck, stereo amp etc. that has a headphone out jack and RCA inputs.

I can get some junk every Saturday for about 5 to 10 bucks.

By stringing them together (Record in and Record out jacks....might be labeled "To tape deck and from tape deck")

You can have several headphone jacks with volume levels.

If you want to get fancy....take the units apart and eliminate all the motors pulleys etc. (Fool the Cassette switch so it will have a signal and record level for volume) Then put all the components in a Radio Shack project box.

I have headphone jacks every 4 feet along the wall in my studio. (Lot'a of boxes and wire). They look cool too!

I only have the headphone jacks on one wall in the sound room. I have never used them all, but often use three or four for vocalists....most of them have heads on their shoulders (though they are mostly empty!)

I just spaced them all out so that in any given setup there will be one near by.

I also installed 12 outlet boxes (24 plugs) so we wont have to run extention cords for amps and effects.

That's cool...a year or so ago I was working on what I called "The Haven Project"...and I'm still kind of working on it...without giving up details, I was planning on running patch bays in the walls all throughout the studios....like every six feet would be a 1/4" patch panel with maybe 10 or 12 ins & outs. When you plugged something in on one of the channels, a light would light up next to that channel on all the bays throughout the room (to avoid people accidentally plugging things into the wrong holes). A pretty simple idea and I worked with my hardware guy on it a little bit.

Basically the idea is that you can stick, for instance, a PA in the corner of a room and the speakers in opposite corners...but you don't have to run a cable all the way across the room for each speaker...you just plug the outputs of the PA and the speakers into the patch bay with short patch cables. Greatly reducing most wirey messes that tend to occure.

Oh man...I'm starting to get the itch for that again...anyone got $500,000 they can loan me? It'll pay off I promise!
