BEFORE YOU START
BI-WIRING YOUR LOUDSPEAKERS
Bi-wiring  improves the  sound of your system because it  divides  the 
high and low frequency signal currents  into separate speaker cables. 
This avoids signal distortions arising from the high and low frequency 
currents  interacting  with  one  another  within  a  single  cable,  as  in 
conventionally wired systems.
You will need:
Speakers – with  four  input  terminals each:  these will be marked HF 
(High Frequency + and –) and LF (Low Frequency + and –).
Loudspeaker  cables  –  two  pairs  of  cables  per  loudspeaker  (which 
may be joined at the amplifier end if your amplifier has only one pair 
of output terminals per channel, as is the case with P7). Or, a suitably 
terminated cable set (a loom, probably prepared by your dealer and 
capable of being used for bi-wiring in one length).
How to bi-wire loudspeakers
1.  Remove the terminal links on the rear of your loudspeakers.
NOTE:    If  you  do  not  remove  the  shorting  links  from  the 
speaker terminals, the speakers will still be single-wired!
2.  Connect the cables as  shown  in  the  diagram below,  ensuring 
correct polarity at all times.
WARNING: Do not make any connections to your amplifier while 
it is switched on or connected to the mains supply. 
Before switching on please check all connections thoroughly, making 
sure bare wires or cables are not touching the amplifier in the wrong 
places (which  could  cause short circuits)  and  you have connected 
positive (+) to positive and negative (–) to negative.
Always ensure that  the volume control on your amplifier is  set  to 
minimum before starting these procedures.
BI-AMPING YOUR SYSTEM
The performance of your system can be further enhanced over that 
achieved with bi-wiring, by extending the principle one stage further 
to include separate amplification for the low and high frequency drive 
units in each loudspeaker enclosure.
To bi-amplify your speakers, connect the speaker terminals from one 
module  to  one  pair  of  terminals  on  the  speaker.  Connect  another 
module,  or  one  channel  of  a  separate  power  amp,  to  the  other 
pair of terminals  on the  speaker,  so  that  two  amplifier channels  are 
connected to that speaker; one for low frequencies and one for high 
frequencies.
Ensure  that  in  all  cases,  the  positive  terminals  on  the  speakers  are 
connected to the positive (red) terminals on the amplifier, and similarly 
for the negative (black) terminals.
NOTE: In order to bi-amplify your speakers, your speakers will need 
to be bi-wirable, and have positive and negative terminals for both high 
frequency (HF) and  low frequency (LF)  information.  If  your speakers 
are bi-wirable, ensure that the links between the HF and LF terminals 
are removed.
How to set up a bi-amped system
1.  Remove the terminal links on the rear of your loudspeakers.
WARNING: This step is essential or damage to your amplifier 
may result which is not covered under warranty.
2.  Connect the cables as  shown  in  the  diagram below,  ensuring 
correct polarity at all times.
3.  Use interconnect cables to connect the OUT socket of the first 
channel to the corresponding IN socket of the adjacent channel 
of the power amplifier.
