These are used to connect the subwoofer to the
line level signal from a pre-amplifier. Please note
that single ended (phono) or balanced (XLR)
connections are available however they must not
be used simultaneously. If only one set of line
outputs is available on your pre-amplifier use Y
connectors to split the L and R signals between
the pre-amplifier and the KEF Reference Series
209 subwoofer or use the Line level LFE input
described below.

This dedicated line level input is specifically for
LFE (Low Frequency Effects) output from a
surround sound processor. Please note that
single ended (phono) or balanced (XLR)
connections are available however they must not
be used simultaneously. The LFE input to the
subwoofer is not be affected by the frequency or
slope settings so there will be no conflict with
the bass management settings applied by the
external surround sound processor.
Microphone input.
Connect the supplied microphone with the XLR
cable to the microphone input and execute
the room correction setup. The microphone may
be removed after this set up has been
fully completed.
External IR input.
The Reference Series 209 subwoofer is only
controllable with the supplied remote control.
However the supplied external IR receiver can
be connected to this input enabling reception
from the remote control even if the subwoofer is
hidden out of site of the remote control and the
main listening position.
