If you have a BeoSystem 4 based BeoVision (like the Horizon) you will see the Shapes in the list of possible speakers,
that you can connect and configure into your tv speakers/multi channel setup.
Just like with any other BeoLab (and a combination of amp and passive speaker) you can choose and give the shapes a role - for example ‘surround speakers’.
Each amplifier module can drive 4 speaker (= 2 + 2) - the amp has a nomal RJ45/PL input which runs two channels.
Configuring the amp (with the Shapes speakers) as speakers should be as easy as with any other BL speaker.
Please notice - if you setup 2 plus two speakers in a R/L configuration with the space between, that you’d need for surround speakers,
you will have to run a longer cables from the amp to the further two speaker set.
If you like, you can mount as many tiles as you please.
Notice - there is no Band On The Wall effect involved here, the processing of the sound takes place in the sound system (True Image) of the BV’s.
Of cource you could also use 4 + 4 speakers - for this you’d need 2 amps.
If it fits into your needs and your room, you could make a Speakers Group of the Shapes speakers to use seperately for easy listening, radio or alike.
In short - a set of 2 + 2 Shapes and the amp can be used just like e. g. a set of 2 BeoLab 3’s.........otherweise there would be no need for these to be in the list of possible speakers on the BV’s!
