There are some draw-backs using the 5000 system with active speakers like the penta's.
The beomaster will basically replace the amp you use now.
The 5000 series has never been designed for active speakers and has no powerlink or speakerlink outputs.
You can however connect your penta's through the line-out plugs of the amp.
Or connecting them through the 3pin speaker connections should work as well
There have been several models of the penta's and you should check which connections they have (You can check on this website)
In all cases the display on the pentas will likely not work.
Yes you can extend the number of speakers with an MCL82 link. (NOT MCL2!!!) The commands of MCL82 are not compatible with the later MCL2.
You will need an white box with an ir-receiver in each room. All of them connected to the Speaker2 plugs of the Beomaster 5000.
The amp in your beomaster will power these boxes and also power the passive speakers connected to them...works a treat....
I still suggest you still into the later 6500 series as they make it easy to hook up your penta's with either powerlink or speakerlink....
Yes there are a lot of 5000 series systems being offered out there, hence the low prices. Do not forget the 5000 series also requires its own type of remote (Only MCP5000 or terminal 5000) and are often hard to find in working condition. (especially on ebay!!!)
FYI : I have been planning to sell my full beosystem5000 for sale, fully reconditioned and upgraded, also 1xMC82 extra room kit and a terminal5000 remote.
For Ipod : there is a simple cable you can buy. Works ok. Not my favourite way to listen to music.
There is also ways to modify an existing ipod dock so you can control it with the beomasters remote (http://home.swipnet.se/ridax/ipod.htm)
For connection your computer : either a headphone plug to tape2 input cable (easy and cheap)
Or if you play music from computer alot and want a bit more control http://home.swipnet.se/ridax/beopc.htm
It's a mix of a special cable with special software.
I use a dedicated mac mini with itunes and I can easily flip playlists and skip songs etc. with this setup.
Personally the computer solution is better (I don't use an ipod that much) as it holds all my music (now over 200 GB) in lossless format.
Later you can add an extra usb dac to that setup in order to get the best digital sound available..... and that will rock those Penta's ;-)
All itunes files are compressed (MP3 codec) and some detail has been lost. What detail is lost cannot be recovered.
Though itunes do now offer higher quality downloads, the rule is simple : the better the quality, the larger the file will be. Best is to rip in a lossless type of file which will give you full cd quality.
