To make connecting up of the XXLS400 as versatile as possible we have included two
separate inputs. One Neutrik Speakon socket and one pairs of gold plated RCA sockets.
This is to facilitate use with both Hi-Fi and AV surround systems.
The high level input, is an unbalanced dual channel (stereo) input that uses a professional
touch proof Neutrik Speakon connector. Signals for this input would normally be sourced
from the left and right speaker terminals of the main system amplifier. The advantage of
this method is that the XXLS400 receives exactly the same signal as being supplied to the
main speakers. This means that the character and tonal balance of the bass from the main
speakers is carried through to the sub bass.
The low level input is via one set of the gold plated RCA to RCA connectors marked as “IN”
on the front panel. Signals for the low level input are unbalanced and would normally be
sourced from the LFE output of an AC3 decoder. Alternatively the low level input can be
connected to a dedicated sub out of a processor (for single outputs connect to the input
marked “Mono”), or to stereo pre-amp output where available.
The XXLS400 comes fitted with four black M8 nylon screws that act as feet and help
prevent the base of the subwoofer from getting scratched. If you wish to take advantage of
the isolating spikes that come supplied with the XXLS400 then please follow the following
fitting instructions:-
First thread one nut per spike on each spike. Now remove the M8 nylon screws from the
bottom of the subwoofer and fit the four spikes. The cabinet can now be leveled by
screwing in or out each spike accordingly. When levelled tighten up each lock nut against
the base of the cabinet.
Caution: Take special care with the spikes as they are very sharp. DO NOT use on
delicate floor finishes
