To make connecting up of the P12-300SB-PR 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 P12-300SB-PR 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 P12-300SB-PR 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 P12-300SB-PR 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
Auto / On - Signal Detect
Tthe P12-300SB-PR is equipped with an auto switch on function, When you first switch on
the power switch the subwoofer will immediately be on and the red LED will illuminate. If
no signal is received for 10 minutes then the subwoofer will automatically go into stand-by
will switch back on once it receives a signal on one of its inputs
