help with my audio setup please

I am almost done with gathering the equipment for my installation,

1> i need advise on the sending audio from my source to the 300metres away amplifier.

Also i would like to know

2>if i should keep my source and amplifier together and send several audio speaker cable 14awg to 300meters away distance just like that,
==or use step up and step up transformers,

or keeping the amplifier near the speakers and sending long audio signal to the amp in different zones, i need good quality and effective sound with not spending too much on cables for which i thought the following

==or use rane bb22 to covert unbalanced line signal to balanced and running through 1.5sq.mm double sheild braided pvc jacket mic cable. but cables will be very expensive.
==or using intelix balun and sending audio through CAT6 cable (and if the cable should be stranded or solid, plenum or general, shielded or unshielded)

Lastly if i want 3 keypads controlling one zone, can i just use one cat6 cable length and distribute data together in 3 or
do i need to run 3 different cat6 cable from source.
there is a function which can make all three work together but i need to know if i can use just single length of cat6 till the keypad area and distribut e ie.

---------------------------------------------------------------------
I have a multi zone setup at my farm, where i will be using 6 zones.

System:
Nuvo Grand Concerto with 9 Oled keypads
Source: nuvo ipod dock, 160gb nuvo m3 server, satellite radio, denon professional cd/mp3 player.
--------------------------------------------------------------------
Zone1: Drawing room,

Bose acoustimass 10 5.1 system with Bose sl2 for operating rear speakers wireless.
Yamaha rx-v2700 amplifier plugged into the preampout of the nuvo system

--------------------------------------------------------------------
Zone 2: Small Garden behind the drawing room

Speakercraft bb835 amplifier, 8 channel 35watts pr channel

2 Bose Freespace 251
2 Bose Freespace 51
1 Bose Freespace DS100SE
1 Klipsh 2 way rock speaker
1 TIC GS10 speaker
-------------------------------------------------------------------
Zone 3 Bedroom

2 ceiling speaker polk audio RC60i powered by nuvo inbuilt amplifier
40 watts per channel
--------------------------------------------------------------------

Zone 4 Fountain Garden Area (400meters away from source)

Cat 6 cable going to the keypad 400mts away
Rane MA6S 6 channel Amplifier 100watts per channel @ 8 ohm
Jensen 6 a/v distribution amp

4 Bose DS100SE 100watts contious @8ohm
2 Bose Frreespace 51 ground speaker
----------------------------------------------------------------------

Zone 5

Cat 6 cabling for 3 keypads?? individual possible?

Speakercraft BB1235 Amplifier ; 12 channel 35 watts pc @ 8ohm

4 Bose Ds100se speakers
4 Bose Freespace 51
1 Speakercraft 820 ROX speaker
1 TIC GS 10 Speaker
2 TIC GS5 Speaker

-----------------------------------------------------------------------

Zone 6

Cat 6 for 2 keypads

Knoll MR1250F Amplifier 12 channel 50watts 8ohm
Crown CP660 Amplifier 65watts 6 channel 8ohm
Kramer VM50AN audio distribution amp

6 Bose DS100SE
4 BOSE FREESPACE 51
2 ROCK SPEAKER
1 SOUNDTUBE XT850 GROUND SPEAKER
2 TIC GS10
3 TIC GS5

I would like to add something.

I just came accross so many different stereo audio baluns like

Cyan says 2000ft distance and around $150 so a pair is $300
Niles it says 2500ft and 110$ a pair
MuxLab send signals till 5000ft 130£ a pair
Intelix 2500ft distance and a pair cost around $150

It seems a bit confusing, as there are so many. and there specs says to use UTP Solid, but dont know if it should be plenum or non plenum?

Also is it a better to use baluns than a coaxial cables, i mean cat5e and cat6 are lot cheaper than coaxial, but any comments?

Hello sanchit.sood

Speak to your kit supplier/installer - they will have detailed experience of what does and doesn't work with your particular kit combination.

It can get dangerous making generalised assumptions about systems based on experience of other systems.

You may get more detailed answers in the Custom Install forum - there are a few Nuvo installers on the boards.

Agreed with Joe.

I can't comment on the balun based solutions, but the conventional signal solutions each have their own problems:

- Voltage drop over long speaker cables will be huge and you'll be losing a lot of power on the way to the speakers.

- Mic cable for 300m will cost ~£300 and unless you find some very low capacitance cable the HF drop will be quite significant.

How important is quality? Have you looked at doing a 100V installation?

I wonder if you might benefit from splitting the system in 2. One set of cables / amps etc. to deal with the house-based areas, and another set to deal with the long-range areas.

I thought of having 100v setup but then the amount of speaker cables would have gone up 7 times the present due to the current 8ohm multi channel amplifier.
I cannot afford to buy 100v amplifier at this stage as i need to drive around 10-18 speakers which will need high power, and amplifier will cost me a lot then.
signal cables is another solution but the cables are very expensive compared to cat6, I was thinking of using cat6 shielded solid core cables. with the baluns as these convert unbalanced signal to balanced and send it through cat5,5e,6 cables and twist in the cables keep distortion away. further shielding helps in the high voltage area and overall setup is quite cheap.
i was thinking of going to the professional installers but it seems that i really dont need much of their help. as i have people who can do conduiting and speakers install on the wall. i think i can do the connections and will get some step down coverters for 110 v amplifiers.

I was just little worries as i have never ever installed any such thing.
