[KAT5] Is this a sensible use of

<P class="MsoNormal"><TT><FONT face="Courier
New" size="2"><SPAN>I need a sense check here so
hopefully someone can comment on my
</SPAN></FONT></TT><FONT face="Courier New"
size="2"><SPAN><BR><TT><FONT
face="Courier New">proposal. First off let me explain my
setup:</FONT></TT><BR><BR><TT><FONT
face="Courier New">1.
Locations</FONT></TT><BR><TT><FONT
face="Courier New">Lounge - home to majority of AV kit at the
moment</FONT></TT><BR><TT><FONT
face="Courier New">Dining room and Sitting room - both have a
pair of speakers running
</FONT></TT><BR><TT><FONT face="Courier
New">from main AV amp (on a 1,2,1+2 switch
box)</FONT></TT><BR><TT><FONT face="Courier
New">Sitting room also h
as TV+VCR+DVD as a secondary viewing
location</FONT></TT><BR><TT><FONT
face="Courier New">Patio - has a pair of speakers running from
main AV amp (via another
</FONT></TT><BR><TT><FONT face="Courier
New">switch
box)</FONT></TT><BR><TT><FONT face="Courier
New">All rooms have plenty of CAT5 running back to a patch panel at
node </FONT></TT><BR><TT><FONT
face="Courier New">zero (office
upstairs).</FONT></TT><BR><BR><TT><FONT
face="Courier New">2. Main
amplifier</FONT></TT><BR><TT><FONT
face="Courier New">AV amp (Arcam Alpha 10 + 10P3) with 4 x
s-video in and 2 x s-video
</FONT></TT><BR><TT><FONT face="Courier
New">out (though one of each is VCR which can either be in our
out)</FONT></TT><BR><TT><FONT fac
e="Courier New">2 x 5 x speaker connections (though only
stereo used for second set
</FONT></TT><BR><TT><FONT face="Courier
New">of speaker points, fed through switches to speakers in other
rooms)</FONT></TT><BR><BR><TT><FONT
face="Courier New">3. Main sources and
connections</FONT></TT><BR><TT><FONT
face="Courier New">DVD --> s-video --> AV
amp</FONT></TT><BR><TT><FONT face="Courier
New">VCR --> s-video --> AV amp (VCR also connected to Tivo
for archiving)</FONT></TT><BR><TT><FONT
face="Courier New">Digibox --> rgb scart --> Tivo -->
RGB to s-video --> AV
amp</FONT></TT><BR><TT><FONT face="Courier
New">DDAR --> AV
amp</FONT></TT><BR><TT><FONT face="Courier
New">Tuner --> AV amp</FO
NT></TT><BR><BR><TT><FONT face="Courier
New">4. Main destinations and
connections</FONT></TT><BR><TT><FONT
face="Courier New">AV amp --> s-video --> Plasma
screen</FONT></TT><BR><TT><FONT
face="Courier New">AV amp --> s-video --> LCD
projector</FONT></TT><BR><BR><TT><FONT
face="Courier New">That is the current setup, it all works
although VCR has to be on AUX
</FONT></TT><BR><TT><FONT face="Courier
New">input to the amp which can be a little confusing. However
there is an </FONT></TT><BR><TT><FONT
face="Courier New">enormous quantity of cable behind the AV
rack that is almost </FONT></TT><BR><TT><FONT
face="Courier New">impossible to maintain (heavy biwired
speaker wire falling on s-video </FONT></TT>
<BR><TT><FONT face="Courier New">cables and
knocking them out etc). So I am considering something
</FONT></TT><BR><TT><FONT face="Courier
New">rather radical (for me anyway) and that is to move source and
'pre-</FONT></TT><BR><TT><FONT
face="Courier New">amp' to node zero with 'power-amp' and
speakers remaining in the
</FONT></TT><BR><TT><FONT face="Courier
New">lounge. There are a few complexities here and this is where I
need </FONT></TT><BR><TT><FONT
face="Courier New">some
advice.</FONT></TT><BR><BR><TT><FONT
face="Courier New">1. Sources that accept physical
media</FONT></TT><BR><TT><FONT
face="Courier New">VCR and DVD - I have a solution to the DVD,
and that is to buy a 400
</FONT></TT><BR><TT><FONT face=&q
uot;Courier New">capacity DVD player to put all my disks in at
once, thereby removing </FONT></TT><BR><TT><FONT
face="Courier New">the need (except for rentals) to access the
deck to change disks. </FONT></TT><BR><TT><FONT
face="Courier New">Then put the monster deck in node zero with
the other sources. But it
</FONT></TT><BR><TT><FONT face="Courier
New">really would not be practical to move the VCR to node zero, so
that </FONT></TT><BR><TT><FONT
face="Courier New">has to stay in the
lounge.</FONT></TT><BR><BR><TT><FONT
face="Courier New">2. Remote
control</FONT></TT><BR><TT><FONT
face="Courier New">Source selection, volume control, transport
control and so on will </FONT></TT><BR><TT><FONT
face="Courier New">have to be
performed from the lounge and affect equipment in node
</FONT></TT><BR><TT><FONT face="Courier
New">zero, so I need IR distribution. I know how to do this so it
is not a </FONT></TT><BR><TT><FONT
face="Courier New">major problem, the CAT5 is already in place
to carry the
signal.</FONT></TT><BR><BR><TT><FONT
face="Courier New">3. Power
amps</FONT></TT><BR><TT><FONT face="Courier
New">With the Arcam setup, the 10P3 power amp is used to control
the rear </FONT></TT><BR><TT><FONT
face="Courier New">and centre speakers, the integrated AV amp
controls the front </FONT></TT><BR><TT><FONT
face="Courier New">speakers. There is a pre<->power
connection between them. It is also
</FONT></TT><BR><TT><FONT face="Courier
New">possible
to attach another power amp to do the front speakers
</FONT></TT><BR><TT><FONT face="Courier
New">(usually for bi-amping) and I intend to buy another 10P power
amp so </FONT></TT><BR><TT><FONT
face="Courier New">that the integrated amp becomes just a
pre-amp.</FONT></TT><BR><BR><TT><FONT
face="Courier New">4. Connecting pre-amp to
power-amps</FONT></TT><BR><TT><FONT
face="Courier New">This is my first suggested use of KAT5, but
I am not sure how many </FONT></TT><BR><TT><FONT
face="Courier New">units will be required. I am assuming that
with 5 channels of </FONT></TT><BR><TT><FONT
face="Courier New">amplification I will need to 'transport' 5
line level signals but I
</FONT></TT><BR><TT><FONT face="Courier
New">don't know what t
hat means in terms of
modules.</FONT></TT><BR><BR><TT><FONT
face="Courier New">5. Connecting local sources to node
zero</FONT></TT><BR><TT><FONT face="Courier
New">This should only be the VCR, but the s-video signal and nicam
sound </FONT></TT><BR><TT><FONT
face="Courier New">need to get to the pre-amp. I will not
worry about the Tivo to VCR
</FONT></TT><BR><TT><FONT face="Courier
New">connection as I have never used it anyway and can probably do
</FONT></TT><BR><TT><FONT face="Courier
New">something in node zero if necessary. So this seems to be
normal use </FONT></TT><BR><TT><FONT
face="Courier New">of a KAT5
pair.</FONT></TT><BR><BR><TT><FONT
face="Courier New">6. Connecting video outputs to
destinations</FONT>&l
t;/TT><BR><TT><FONT face="Courier New">I
won't mention the switcher but I certainly have 2 x s-video output
</FONT></TT><BR><TT><FONT face="Courier
New">to s-video
destination.</FONT></TT><BR><BR><TT><FONT
face="Courier New">So, it seems that I have 5 line level audio
signals to get from node
</FONT></TT><BR><TT><FONT face="Courier
New">zero to the lounge. Two s-video signals to get from node zero
to the </FONT></TT><BR><TT><FONT
face="Courier New">lounge (though only 1 will be used at a
time). And one s-video +
</FONT></TT><BR><TT><FONT face="Courier
New">stereo to get from the lounge to node
zero.</FONT></TT><BR><BR><TT><FONT
face="Courier New">At present I think I have 2 x Rx and 3 x Tx
units, all are standard </FONT><
/TT><BR><TT><FONT face="Courier
New">versions. Please advise as to the best combination of units
(or </FONT></TT><BR><TT><FONT face="Courier
New">Keith, please advise on any custom units that might be
useful). The </FONT></TT><BR><TT><FONT
face="Courier New">end goal is to remove kit from the lounge
(high WAF) and to separate
</FONT></TT><BR><TT><FONT face="Courier
New">local 'heavy duty' speaker wiring from central 'sensitive'
</FONT></TT><BR><TT><FONT face="Courier
New">interconnects.</FONT></TT><BR><BR><TT><FONT
