Stereo input
When using a two-channels pre-amplifier or an amplifier, equipped with
pre-out or preamp-out line outputs, the Sub Utopia Be must be connected
through RCA stereo inputs "line inputs Right/Left". Some High End amplifiers
or A/V receivers use Balanced XLR connections for immunity electromagnetic
interference.
LFE input
When using a multi-channel amplifier, the single LFE input of the Sub Utopia
Be should be connected to the mono "Subwoofer" RCA or XLR output of
the audio/video amplifier. In that precise case, the electronic crossover of
the Sub Utopia Be will be off. Considering the fact that the audio/video
amplifier already this feature, this configuration is recommended for home
theatre use only.
Dual stereo/Multi-channel connections
To configure the Sub Utopia Be for a dual system where you intend to play
both stereo two channel CD's and multi channel formats, follow first the
"stereo only" set-up.
The phase control acts on both pre-amplifier sections – that of the stereo
inputs and the LFE. It is easer to find the perfect position using the stereo
set-up procedure.
Once you are happy with the stereo set-up, follow the multi-channel set-up,
with the exception of the phase adjustment.
Once the set-up is complete you can enjoy the best of both worlds: whilst
listening to a music CD the Sub Utopia Be will compliment perfectly your
main loudspeakers usefully extending bass deeper. With multi-channel
formats the Sub Utopia Be will continue to extend the response of your
main loudspeakers, but in addition will in the extra information recorded
on the LFE channel.
