RE: In-ceiling amplifiers

["Nikola Kasic" <nikola@xxxxxxx>]

Richard,
I was looking for the same for a quite a while, and couldn't find any
appropriate solution. Therefore, no Slimp, extreamer or anything similar
yet in my bedroom.
Ideally, I would like it to be thin enough so it can fit between
plasterboard and concrete wall at my flat, which is 1.5" (3.8 cm). I
think that's the standard in most newly built homes, because that's the
thickness of wooden joists.
Then I would like it to be safe to be put there, which means that it
doesn't generate excessive heat and will feel fine there with no
ventilation holes.
Also, you need to leave access to it, just in case you need to change
fuse or amp without diggin' the wall. Therefore, I would like it to be
able to place it behind the plasterboard (as described above) through
standard single drylining box.
Ideally it should fit in, but probably not possible, therefore if I can
use one of the existing drylining boxes (switches, sockets etc.) to
place amp behind plasterboard, it would be fine.
For the power, I think 30W should be enough. Going above would probably
generate too much heat, but generally speaking the higher power rating,
the better, as long as it doesn't compromise conditions mentioned above.
Supplying audio/power/IR over the single cable is always tricky. You
need to take care of interference between signals, neighbouring wires,
if any, and try to find a way how to reduce a risk of burning something
if you plug that cable accidentaly into network equipment. Maybe the
best practice would be not to use RJ45 connectors but something
different.
On the other side, how do you plan to sort power supply?
I would prefer transformer to be burried also behind the plaster, and
not to have wall wart.
Maybe the best way would be to cut hole for dry lining box next to
existing socket, place amplifier in the woid behind plaster through that
hole and then put the dry lining box. Then place transformer into dry
lining box and supply the power from the neighbouring socket.
You then put blanking plate over, and if needed make a few ventilation
holes on it.
Just some of my ideas...
Regards,
Nik

Simon,

we are thinking of building and marketing something like this, but using
CAT5 as a input to take audio/power/IR. How do you want to get signal
and
power to it? Tell me what would be ideal, and maybe we could make
something
in time. We have all the prototyping done, it's a question of exactly
what
in/outs, who wants it, and for what to determine the final shape &
flavours
it comes in. So it's good to here of some real-world needs.

Thanks,

Richard

I am putting together a whole house audio network using SlimP3 devices.
To
keep everything neat and tidy we will be installing ceiling speakers.

What I am looking for is a simple single input stereo amp to place in
the
ceiling void too.  It doesn't need to shake the earth or get too hot!

Any ideas?
